Steam holds 74% of the PC digital distribution market and set a new all-time concurrent user record of 41.81 million in January 2026. Microsoft’s Xbox App and Store–backed by 250 million monthly users and a 30% year-on-year jump in PC Game Pass memberships–is making a serious push for the second slot on Windows PCs. With Project Helix positioning the next Xbox to run Steam, and Game Pass Ultimate slashed to $22.99/month, the competitive picture in mid-2026 has never been more complex. This comparison tests both platforms across library size, revenue split, feature depth, exclusive content, modding, and real-world performance so you can decide where to spend–and where to play.

Quick Verdict: Steam vs Microsoft Store 2026
Steam wins on raw library size, mod ecosystem, and developer mindshare. The Microsoft Store (Xbox App) wins on subscription value, cross-platform progression, and day-one Game Pass access to major Microsoft titles. Neither platform is obsolete–most serious PC gamers use both simultaneously.
| Criterion | Steam | Microsoft Store (Xbox App) | Winner |
|---|---|---|---|
| Library size | 117,881 titles (Nov 2025) | Undisclosed total; hundreds via Game Pass | Steam |
| Market share (PC digital) | ~74% | ~5–8% estimated | Steam |
| Monthly active users | 132 million | 250M+ (store ecosystem) | Tie |
| Developer revenue split | 70/30 (30% Valve cut) | 80/20 (20% Microsoft cut) | Microsoft Store |
| Subscription tier | None (à la carte) | PC Game Pass $13.99/mo | Microsoft Store |
| Mod support | Steam Workshop (mature) | Game-dependent, less mature | Steam |
| Cross-platform saves | Steam Cloud (PC only) | Xbox Play Anywhere (PC + console) | Microsoft Store |
| DirectStorage support | Broad (via Windows/Steamworks) | Native for Xbox titles | Tie |
| DRM policy | Steamworks DRM (optional) | Xbox DRM (required) | Steam |
| Steam Deck compatibility | Full Deck support | Not supported natively | Steam |
| Family sharing | Steam Families (up to 5) | Limited to account owner | Steam |
| Concurrent record (2026) | 41.81M (Jan 2026) | Not disclosed | Steam |
Market Share and User Base: Steam’s Dominant Lead
Steam’s market dominance is structural, not accidental. According to 2025–2026 industry reports, Valve’s platform controls approximately 74% of global PC digital game distribution–roughly 25 times the revenue share of Epic Games Store and an even larger multiple over Microsoft’s PC store. The raw user numbers back this up: 132 million monthly active users and 69 million daily active users as of 2025, with a new concurrent peak of 41.81 million users online simultaneously in January 2026.
Microsoft’s ecosystem tells a different story. The broader Microsoft Store serves more than 250 million monthly users globally, but this figure encompasses the entire Windows app marketplace–productivity software, browsers, Office tools, and games alike. Isolating PC gaming users specifically, the Xbox App for PC has benefited from a 30% year-on-year increase in PC Game Pass memberships reported in February 2025, and gaming contributed to a 5% year-on-year rise in Microsoft’s overall gaming revenue in fiscal Q3 2025.
The gap between these platforms reflects the history of each. Steam launched in 2003 as a mandatory update client for Counter-Strike, then evolved into the de facto PC gaming storefront. It now accounts for an estimated $10.8 billion in gaming revenue during 2024, with January–November 2025 revenue reaching $16.2 billion–a 50% increase over full-year 2024. Microsoft’s gaming ambitions on PC accelerated with the $68.7 billion Activision Blizzard acquisition in 2023, but converting that content investment into Microsoft Store install-base growth has proven slower than anticipated.
What makes Steam’s lead defensible isn’t just habit–it’s the Steam hardware survey, which provides a living snapshot of PC gaming configurations. As of May 2026, Windows 11 64-bit accounts for 69.76% of Steam users, with Windows 10 at 23.99%. This data is unique to Valve and makes Steam an irreplaceable infrastructure layer for game developers targeting PC players. No equivalent public dataset exists for the Xbox App’s PC user base.
The market dynamics favor Steam’s continued dominance in the short term. Steam’s $16.2 billion in revenue across January–November 2025 represents a 50% jump over full-year 2024–a growth rate that outpaces most gaming segments. By contrast, Microsoft’s gaming revenue growth in the same period is driven by subscription expansion (PC Game Pass) rather than Microsoft Store PC game sales, suggesting the two platforms are growing in different directions: Steam through volume, Microsoft through recurring subscriptions.
Library Size and Content: 117,881 vs. a Moving Target
Steam’s library reached 117,881 titles by November 2025, with 18,634 new games added in 2024 alone–a 31.75% increase over 2023’s 14,131 releases. The platform publishes this data transparently through SteamDB and its own annual statistics, making it easy to track growth trends. The volume includes everything from AAA titles like Elden Ring and Cyberpunk 2077 to thousands of indie games, early access titles, and free-to-play experiences. As of mid-2026, over 50,000 games on Steam are available for under $10, with the long-tail indie catalog providing genuine discovery value through Steam’s recommendation engine.
Microsoft does not publish a comparable, audited total for the Xbox App PC game catalog. Industry analysis in 2026 consistently describes Steam as having “the largest library” while characterizing the Microsoft Store as “competitive” but emphasizing ecosystem integration over raw game count. A 2025 quality audit found that 39% of new releases in the Microsoft Store were flagged as low-quality titles designed primarily for earning Gamerscore points–indicating high volume but inconsistent quality density compared to Steam’s curated discovery algorithms.
The Microsoft Store’s content strength lies in its exclusive or day-one-on-Game-Pass titles. Key games from Bethesda (post-acquisition), Activision Blizzard, and Xbox Game Studios typically appear on the Xbox App on the same day as Xbox consoles. Titles like Clair Obscur: Expedition 33 and Hollow Knight: Silksong (anticipated) are prominently featured. However, a critical 2026 change: Call of Duty games are no longer Day One on Game Pass–they are added approximately one year after release, which significantly reduces a key content advantage that drove Game Pass subscriptions in 2023–2024.
For developers and publishers, Steam’s discovery system–new release sections, wishlists, “More Like This” recommendations, community curator lists, and the Steam Next Fest demo event–remains unmatched. The Microsoft Store’s 2025 search rearchitect improved relevance and intent-awareness, but it operates from a significantly smaller user base and a less mature review ecosystem. A game with 10,000 positive Steam reviews carries discovery weight that equivalent Xbox App ratings cannot replicate at the same scale.
Exclusive Games by Platform in 2026
| Platform | Notable Exclusives / Timed Exclusives (2026) | Exclusivity Type |
|---|---|---|
| Steam only | Valve games (Half-Life, Portal, DOTA 2, CS2), Steam Early Access originals | First-party permanent |
| Xbox App / Microsoft Store | Gears E-Day, Clockwork Revolution, Microsoft Flight Simulator 2024 | Xbox console + PC exclusive (also on Steam PC) |
| Both platforms simultaneously | Forza Horizon 5, Halo Infinite, Sea of Thieves, Starfield, Avowed, Indiana Jones | Xbox Play Anywhere (cross-listed) |
| Epic Games Store first | Various third-party timed exclusives (~12-month window) | Timed exclusive, later on Steam |
| Steam + Xbox App same day | Most major third-party AAA (Cyberpunk 2077, Elden Ring, GTA V, etc.) | Simultaneous multi-platform release |
The 2026 Xbox Games Showcase confirmed a strategic pivot: Gears E-Day and Clockwork Revolution are permanent Xbox console exclusives–they will not appear on PlayStation 5. Critically for this comparison, both will also release on PC via Steam and the Xbox App, meaning Steam users are not locked out of Xbox Game Studios content. This dual-platform PC approach defines Microsoft’s current strategy: compete through subscription economics and ecosystem integration rather than PC storefront exclusivity against Steam.
Revenue Split: Which Store Pays Developers More?
For developers choosing where to distribute their games, the revenue split is often the deciding factor in initial release planning. Steam uses its long-standing 70/30 split–developers keep 70%, Valve takes 30%. This cut remains constant for most games, with improved percentages only available after a title earns $10 million (25% cut) or $50 million (20% cut) in lifetime revenue on Steam. For the vast majority of indie and mid-tier developers who never reach these thresholds, the standard 70/30 applies permanently.
Microsoft operates differently. The Microsoft Store for PC games offers developers an 80/20 split–developers keep 80%, Microsoft takes 20%. This is more generous than Steam’s standard rate and sits between Steam and Epic’s 88/12 model. Microsoft introduced expanded inline install features in late 2025 and multi-app install capabilities in November 2025, allowing developers to bundle productivity or game suites in a single installation event, potentially improving both discovery and conversion rates without changing the core revenue split.
| Platform | Base Developer Cut | Improved Rate | Condition | Annual Revenue Required |
|---|---|---|---|---|
| Steam | 70% | 75% / 80% | After $10M / $50M lifetime revenue | Very high bar for indie devs |
| Microsoft Store (PC) | 80% | Not publicly specified | Standard rate for all | N/A |
| Epic Games Store | 88% | 88% | Standard; + UE5 royalty if applicable | Plus potential upfront minimum guarantees |
| GOG | 70% | 70% | Standard rate, DRM-free | N/A |
| itch.io | 90%+ | Developer-set (0–100%) | Developer controls the fee rate | Lowest traffic volume |
For indie developers, the Microsoft Store’s 80/20 split is materially better than Steam’s standard 70/30–on 10,000 copies at $15 each, that’s a $15,000 difference. But the practical impact is significantly muted by Steam’s superior discovery engine. A game selling 10,000 copies on Steam–where organic discoverability through wishlists, reviews, and Steam tags is well-established–will typically outperform the same title on Microsoft Store despite the lower platform cut. The Valve antitrust trial (heading to court in 2026) focuses in part on whether Steam’s most-favored-nation pricing clauses prevent developers from offering games cheaper elsewhere–a policy that effectively locks in Steam’s pricing power regardless of its commission rate.
Epic addressed its discovery deficit by offering upfront “minimum guarantee” deals (often $1 million–$10 million advances) alongside its 88/12 split, something Microsoft hasn’t widely matched for PC-only titles. The Microsoft Store’s Game Pass payouts to developers operate on a separate “engagement-based” model rather than per-sale revenue, which complicates direct comparisons. Developers in the Game Pass program receive payments based on hours played rather than units sold–a model that rewards games with high engagement and long play sessions over titles with high completion rates.
Pricing and Subscriptions: à la Carte vs. Game Pass
Steam has no subscription model. Every game is priced individually, with seasonal sales and regional pricing as the primary value levers. The Steam Summer Sale (running June 25–July 9, 2026) is the platform’s biggest discount event, following the 2025 Summer Sale that generated an estimated $876 million in gross merchandise value. There is no recurring fee to use Steam’s client or access community features–the platform monetizes purely through game sales and a 15% cut on Steam Community Market transactions.
Microsoft’s value proposition is anchored in Game Pass. As of 2026, PC Game Pass costs $13.99/month, following a price reduction from $16.49/month after backlash over the 2023 price hike. Game Pass Ultimate–which includes PC, console, and Xbox Cloud Gaming–costs $22.99/month (reduced from $29.99/month), representing an annual cost of $275.88/year. This includes access to hundreds of games without individual purchase, day-one access to all Xbox Game Studios titles, and cloud gaming through xCloud.
The economics of each model favor different playstyles. A gamer who plays three or more new AAA games per year from Microsoft’s studios will generally break even or save money with Game Pass Ultimate compared to buying those titles individually at $60–$70 each. However, games accessed through Game Pass are lost when the subscription lapses–you own nothing permanently. Steam purchases are permanent, subject to Steam’s terms of service, and accessible as long as Valve maintains the platform. This ownership-versus-access tradeoff is the defining philosophical divide between the two platforms.
Feature-by-Feature Comparison: Steamworks vs. Xbox Ecosystem
Steam’s feature advantage is concentrated in its Steamworks SDK–a thorough toolkit that provides developers with achievements, cloud saves, mod support (Steam Workshop), matchmaking, leaderboards, community hubs, detailed analytics, Steam Input for controller mapping, Remote Play Together for online co-op on single-player games, and the Steam Overlay. These are integrated at the platform level and available to every developer at no additional cost beyond the revenue split. Steam Workshop alone hosts millions of user-created mods across games like Skyrim, Cities: Skylines, and Garry’s Mod–representing an ecosystem that no competing storefront has been able to replicate.
Microsoft’s Xbox App provides fundamentally different strengths. The platform’s core differentiator is cross-device integration: games purchased as Xbox Play Anywhere titles work on both Xbox consoles and Windows PCs with a single purchase, with cross-save and cross-progression supported natively. Xbox Live achievements are unified across console and PC. The Xbox overlay provides access to the Xbox Game Bar (Win+G), social features, party chat, and cloud gaming through a single interface that works on top of any application–including Steam games.
Mod Support: Steam Workshop vs. Microsoft Store
Modding is where Steam’s maturity advantage is most pronounced. Steam Workshop integrates directly into game library pages–users subscribe to mods in one click, which automatically download and update through the Steam client. This seamless integration is one reason games like The Elder Scrolls V: Skyrim continue to sell well a decade after release. Modding discovery and installation on Steam require zero technical knowledge, making community-created content accessible to mainstream players, not just power users.
The Microsoft Store/Xbox App situation is more complex. Games purchased through the Microsoft Store use the Universal Windows Platform (UWP) packaging format, which historically restricted access to game files and made modding difficult or impossible. Microsoft has improved this substantially–many Xbox App games now install to an accessible directory compatible with external modding tools like Nexus Mods or ModDB. However, game-specific DRM remains a constraint: titles with strict anti-tamper systems may block mods regardless of platform. The practical verdict: if modding is central to your gaming experience, Steam is the significantly more reliable platform.
| Technical Feature | Steam | Microsoft Store (Xbox App) | Notes |
|---|---|---|---|
| DirectStorage | Supported (developer opt-in) | Native for Xbox-optimized titles | Microsoft first-party games better optimized |
| Auto HDR | Supported (Windows 11) | Supported (Windows 11) | OS-level feature, equal on both |
| Variable Refresh Rate | Supported | Supported | Equal; depends on monitor/GPU |
| Controller support | Steam Input (350+ controller profiles) | Xbox Controller native | Steam more versatile for non-Xbox pads |
| Overlay (in-game) | Steam Overlay (browser, chat, achievements) | Xbox Game Bar (Win+G) | Both available simultaneously |
| Per-game launch options | Full command-line support | Limited | Steam significantly more flexible |
| Proton / Linux gaming | Proton compatibility layer | Not supported | Steam uniquely supports Linux gaming |
| Remote Play | Remote Play Together, Steam Link | Xbox Cloud Gaming | Different models: local vs. cloud |
| Family sharing | Steam Families (up to 5 members) | Account-bound, limited sharing | Steam significantly better |
| Mod ecosystem | Steam Workshop (millions of mods) | Game-dependent, external tools only | Steam vastly superior |
Steam Deck: Steam’s Hardware Moat in 2026
The Steam Deck is one of the most significant strategic advantages Steam holds over Microsoft in the PC gaming ecosystem. Valve’s handheld gaming PC runs SteamOS and integrates seamlessly with a user’s existing Steam library. The Steam Deck Verified/Playable certification system rates games for compatibility, and as of mid-2026, over 19,000 Steam games carry a Verified or Playable rating. Valve does not publish exact hardware sales figures, but multiple market estimates place Steam Deck units sold in the millions by 2026, with the OLED model driving renewed sales since late 2023.
Microsoft’s Xbox App has no native Steam Deck support. While you can technically install Windows on a Steam Deck and then install the Xbox App, this undermines the device’s plug-and-play experience and is not officially supported by Valve. For gamers who own or plan to purchase a Steam Deck, every game in their Steam library is immediately available and playable. Games purchased through the Xbox App are inaccessible on the device in its native SteamOS configuration. Xbox Cloud Gaming (browser-based xCloud) works on Steam Deck through Chromium, providing a workaround for Game Pass titles–but it requires an internet connection and doesn’t match the offline-capable native Steam Deck experience.
The hardware integration creates a compounding effect. As Steam Deck adoption grows, the proportion of PC gamers with a financial stake in Steam-compatible purchases increases, further entrenching Steam’s install base. This is a strategic moat that Microsoft’s current approach–a subscription service accessed through a software client–cannot replicate without competing hardware. Interestingly, Project Helix may address this in 2027 if it ships as a Windows PC capable of running Steam natively.
5 Real-World Use Cases: Which Platform Fits Your Setup?
Use Case 1: Hardcore PC Gamer, Large Library
Scenario: You own 200+ games, play across multiple PCs, and value mod support, family sharing with four household members, and Steam Deck compatibility.
Winner: Steam. The Steam Families plan supports up to five family members sharing libraries. Steam Workshop provides direct in-client mod management for thousands of moddable games. Steam Deck compatibility means your entire library is portable. The Microsoft Store’s Xbox App doesn’t support native family library sharing at scale, and its mod ecosystem is significantly less mature for the types of games (RPGs, strategy, simulators) that benefit most from community content.
Use Case 2: Console + PC Crossover Player
Scenario: You own an Xbox Series X and a gaming PC, and you want to start games on console and continue them on PC–or share purchases across both devices.
Winner: Microsoft Store (Xbox App). Xbox Play Anywhere is unmatched for this use case. Buy a game once through the Microsoft Store, and it’s available on both Xbox and PC. Cross-save ensures you never lose progress switching devices. Game Pass Ultimate at $22.99/month adds Xbox Cloud Gaming, letting you continue on a mobile browser when neither device is available. Steam offers no console bridge whatsoever–purchasing a game on Steam is a PC-only transaction.
Use Case 3: Indie Developer Choosing a Launch Platform
Scenario: You’re launching a solo-developed indie game and need to choose your primary PC distribution channel.
Winner: Steam (with a caveat). Steam’s discovery engine–wishlists, tags, “More Like This” recommendations, curator lists, Steam Next Fest–gives indie games organic reach that the Microsoft Store simply cannot match at current user volumes. However, Microsoft’s 80/20 revenue split versus Steam’s 70/30 means 10 additional percentage points of revenue per sale. For most indie developers, Steam’s traffic and discovery value outweighs the revenue split difference. Publishing on both platforms costs nothing incremental and is the optimal dual-release strategy.
Use Case 4: Budget-Conscious Gamer
Scenario: You want to play the most games for the least money per month and don’t mind rotating through titles rather than building a permanent owned collection.
Winner: Microsoft Store (Xbox App). PC Game Pass at $13.99/month provides access to hundreds of games, including all Xbox Game Studios titles on day one. If you’re primarily interested in Microsoft’s output–Halo, Forza, Starfield, Avowed, Indiana Jones and the Great Circle–Game Pass eliminates individual game costs entirely. The Steam alternative requires buying each title at $40–$70. The breakeven point: two to three new Game Pass-eligible games per year you’d otherwise purchase at full price covers the annual subscription cost. For heavy players who churn through games quickly, the value proposition is even stronger.
Use Case 5: Linux or Steam Deck Gamer
Scenario: Your primary gaming machine runs Linux (Ubuntu, Fedora, Arch) or SteamOS, or you own a Steam Deck.
Winner: Steam (no contest). The Microsoft Store and Xbox App have no Linux support whatsoever. Steam’s Proton compatibility layer allows thousands of Windows-native games to run on Linux with minimal configuration. As of mid-2026, over 19,000 Steam games are rated Verified or Playable on Steam Deck. If you’re a Linux gamer, the Xbox App is simply not a viable platform. For running Epic and GOG games on Linux alongside Steam, see our guide to the Heroic Games Launcher setup.
Expert Opinions: What Creators Say in 2026
Developer-focused YouTube creator Fireship has noted that Steam’s 30% cut remains a source of frustration for indie developers, calling it “the cost of doing business on the internet’s most important PC gaming mall.” He argues that while Microsoft’s 80/20 split is objectively better for developers, “the traffic isn’t there–Steam is where the players are, and players don’t go looking for good games on the Microsoft Store the way they browse Steam’s front page.”
MKBHD (Marques Brownlee) has covered the Xbox ecosystem extensively and describes Game Pass as “genuinely transformational for casual PC gaming” while acknowledging that “for people who take their PC gaming seriously–mods, Steam Workshop, community guides–Steam is still the center of gravity.” His assessment: the two platforms are complementary rather than directly competitive for most users. “I use both. Game Pass for day-one Xbox stuff, Steam for everything else.”
Backend developer content creator ThePrimeagen approaches the debate from an infrastructure perspective: “The Microsoft Store has gotten dramatically better since its awful Windows 8 era. But Steam has 20 years of developer tooling advantage–Steamworks, the API, the community features. You don’t just copy that overnight. For now, Steam is where serious games live, and Game Pass is where you go to try things you wouldn’t pay $70 for.”
The consensus among power users and creators is that Steam and the Xbox App occupy different but overlapping niches. No single platform dominates both value and features; the optimal setup depends on gaming hardware, budget, and content preferences. Notably, all three creators emphasize using both platforms simultaneously rather than choosing between them.
Project Helix in 2027: The Comparison That Might Become Irrelevant
The most significant long-term shift in this comparison isn’t happening in 2026–it’s coming in 2027. Microsoft’s next-generation console, known internally as Project Helix, is reportedly designed to run Steam alongside the Xbox ecosystem. According to reporting from early 2026, Microsoft’s strategy involves creating a device that functions as both an Xbox console and a Windows PC, enabling users to switch between the Xbox interface (with Game Pass and Xbox exclusives) and a Windows desktop (with full Steam access).
If Project Helix ships as described, the Steam versus Microsoft Store debate on PC becomes largely moot for the console-PC crossover segment–the next Xbox would be the platform that runs both. For now, Steam and the Xbox App coexist separately on Windows, and the comparison above reflects the 2026 reality. But the strategic implication is significant: Microsoft appears to be conceding that Steam’s 74% PC market share cannot be dislodged through exclusivity or a competing storefront alone. Instead, the strategy is to make Microsoft’s device the hardware layer on which Steam’s library runs, while capturing subscription revenue through Game Pass.

Migration Guide: Moving Between Steam and Xbox App
Many PC gamers have libraries on both platforms with games that exist in both stores. Understanding what transfers–and what doesn’t–is essential before consolidating purchases or switching primary platforms.
Switching Games from Steam to Xbox App
What transfers: Nothing transfers automatically. Game purchases are non-transferable between platforms. If you bought Forza Horizon 5 on Steam, you cannot move that purchase to the Xbox App. Achievements are separate between platforms (Steam achievements vs. Xbox Achievements/Gamerscore) and do not sync or transfer.
Save files: Some games support cross-platform saves via developer-implemented cloud solutions. Starfield, for example, allows cloud saves that can be accessed if you start the game fresh on a new platform. Not all games support this–verify on a per-game basis before switching platforms to avoid losing progression.
Recommended workflow: If a game you own on Steam is also available on Game Pass, play it through Game Pass on the Xbox App without repurchasing. Your Steam copy remains available. This is the most practical approach–use Game Pass to access the Microsoft Store library without abandoning your existing Steam investment. The two clients coexist without technical conflict on both Windows 10 and Windows 11.
# Windows PowerShell: Verify both clients are installed
Get-AppxPackage -Name "Microsoft.GamingApp" | Select Name, Version
# Confirms Xbox App installation
Get-Command steam -ErrorAction SilentlyContinue | Select Source
# Confirms Steam path (typically C:\Program Files (x86)\Steam\steam.exe)
# List Xbox App game install locations (Windows 11)
# Games install to: C:\XboxGames\ or custom drive via Xbox App settingsMoving from Xbox App to Steam
Game Pass to Steam purchases: Games played through Game Pass can be purchased outright through the Xbox App or Microsoft Store if you want to own them permanently after your subscription ends. Steam does not honor Xbox App purchases–you would need to rebuy at full Steam price. Before your Game Pass subscription lapses, purchase any titles you want to keep permanently while still having active access.
Save file migration: For Xbox Play Anywhere games, your save data is stored in the Xbox cloud. If you purchase the same game on Steam, you will need to start fresh or manually locate and transfer save files if the game uses standard Windows save directories. This process is game-specific and not guaranteed. Always back up saves before switching platforms for a game mid-playthrough.
Total Cost of Ownership: Annual Scenarios
| Scenario | Steam Annual Cost | Xbox App Annual Cost | Ownership |
|---|---|---|---|
| 1 AAA game/month at $60 | $720/year (owned forever) | $167.88/year (PC Game Pass) | Steam: permanent; Xbox: subscription-locked |
| 3 AAA + indie games/year | ~$230/year (owned) | $167.88/year (PC Game Pass) | Xbox slightly cheaper; Steam builds library |
| Heavy Steam Sale shopper | ~$100–$150/year (70–90% discounts) | $167.88/year (PC Game Pass) | Steam cheaper with disciplined sale buying |
| Xbox console + PC gaming | $720+/year (separate purchases per platform) | $275.88/year (Game Pass Ultimate) | Xbox dramatically cheaper with console cross-buy |
| Linux or Steam Deck user | Steam-only viable ($varies) | Not compatible with Linux/SteamOS | Steam only option; zero choice |
Pros and Cons: Complete Summary
| Steam Pros | Steam Cons |
|---|---|
| Largest PC library (117,881 titles) | 30% developer cut (highest standard in industry) |
| 74% market share = best game discovery | No subscription option–all purchases individual |
| Mature Steam Workshop mod ecosystem | No console cross-progression capability |
| Steam Deck / SteamOS native support | Antitrust trial ongoing (possible forced changes) |
| Steam Families (up to 5 shared accounts) | DRM still present on most titles via Steamworks |
| Proton enables Linux gaming | Storefront algorithm can bury new indie games |
| Deep seasonal sales ($876M GMV Summer 2025) | No built-in console cross-buy or Play Anywhere |
| Steamworks: 20 years of developer tooling | Customer support quality inconsistent |
| Microsoft Store (Xbox App) Pros | Microsoft Store (Xbox App) Cons |
|---|---|
| 80/20 developer split (better than Steam’s 70/30) | Smaller game library vs. Steam |
| PC Game Pass at $13.99/mo (best value for Xbox titles) | Game ownership lost when subscription lapses |
| Xbox Play Anywhere (one purchase = PC + Xbox) | Limited modding support vs. Steam Workshop |
| Cross-save between Xbox console and Windows PC | 39% of 2025 releases were low-quality Gamerscore titles |
| Day-one Xbox Game Studios releases on Game Pass | No Steam Deck / Linux support |
| Xbox Cloud Gaming included in Ultimate ($22.99) | CoD no longer Day One on Game Pass (2026 change) |
| DirectStorage optimization on first-party titles | Historically weaker game discovery algorithm |
| Unified Xbox Achievement system (PC + console) | Less mature developer tools vs. 20-year Steamworks |
Final Verdict: Steam vs Microsoft Store in 2026
Steam is the better platform for most PC-first gamers in 2026. The data is unambiguous: 74% market share, 132 million monthly active users, 117,881 titles, a mature modding ecosystem, Steam Deck hardware integration, and full Linux support through Proton. Steam’s 30% developer cut is the platform’s weakest point, but for players–as opposed to developers–this is immaterial to the gaming experience. The permanence of game ownership and the depth of the Steam community features (Workshop, reviews, curators, Remote Play) remain unmatched by any competitor.
The Microsoft Store (Xbox App) is the better platform if you own an Xbox console, play Game Pass titles heavily, or value cross-platform progression over game ownership. PC Game Pass at $13.99/month delivers compelling value for gamers who play Microsoft’s output regularly. Cross-save between Xbox and PC is a genuine daily-use advantage that Steam cannot replicate. The 80/20 developer revenue split is more equitable than Steam’s model, and recent 2025 improvements to search, install management, and multi-app installs make the platform meaningfully better than it was in its Windows 8 era nadir.
The practical recommendation for most PC gamers in 2026: install both and use each for what it does best. Steam as your primary library for third-party and indie games, permanent ownership, modding, and Steam Deck play. The Xbox App with PC Game Pass for Microsoft’s day-one releases, Xbox console cross-progression, and cloud gaming. At $13.99/month for PC Game Pass alongside a Steam library built through years of seasonal sales, the total investment is reasonable for the breadth of content it unlocks.
As Project Helix approaches in 2027, this two-platform answer may collapse into a single device that runs both. Until then, Steam’s 74% market share and 20 years of ecosystem depth mean it remains the default choice–and the Microsoft Store is the best complement available.

FAQ: Steam vs Microsoft Store 2026
Is the Microsoft Store the same as the Xbox App?
They are related but distinct. The Microsoft Store is the full Windows app marketplace accessible from the Start menu, covering apps, games, and productivity tools. The Xbox App is a dedicated gaming client for PC that connects to the Xbox ecosystem, Game Pass, and your Xbox library. PC games can be accessed through either interface, but the Xbox App is the recommended launcher for gaming on PC–it offers better library management, Game Pass integration, and in-game overlay features.
Can I play Xbox App games on Steam Deck?
Not natively. The Steam Deck runs SteamOS by default, and the Xbox App is a Windows application with no Linux port. You can install Windows on a Steam Deck and then install the Xbox App, but this eliminates the native SteamOS experience and is not officially supported by Valve. For Game Pass content on Steam Deck without installing Windows, Xbox Cloud Gaming works through the Chromium browser in SteamOS’s desktop mode–streaming games via xCloud requires an internet connection and a Game Pass Ultimate subscription.
Does buying a game on Microsoft Store also give me the Xbox console version?
Only for Xbox Play Anywhere titles. These games come with a single purchase that grants access on both Xbox consoles and Windows PC via the Microsoft Store, with shared cloud saves and cross-progression. Not all Microsoft Store games are Play Anywhere–check the product page for the Play Anywhere logo before purchasing. Major Microsoft Game Studios titles are typically Play Anywhere; third-party games may not be.
Which platform has better game prices?
Steam’s seasonal sales (Summer Sale, Winter Sale, Autumn Sale) regularly offer discounts of 70–90% on major titles. The Steam Summer Sale 2026 runs June 25–July 9 with thousands of deals. The Microsoft Store runs sales and Microsoft Rewards rebates too, but Steam’s discount depth and frequency are unmatched for building a permanent owned library at low cost. For players who want new releases without waiting for sales, Game Pass is cheaper for Microsoft’s own titles–paying $13.99/month versus $60–$70 per game.
Is Steam facing antitrust action in 2026?
Yes. Valve faces a US antitrust lawsuit over its 30% commission and alleged most-favored-nation pricing clauses that prevent developers from selling games at lower prices on competing platforms. The case is heading toward trial in 2026. Regardless of outcome, the suit has not changed Steam’s current pricing or terms as of mid-2026.

What is the Microsoft Store’s revenue split for developers?
The Microsoft Store for PC games operates on an 80/20 revenue split–developers keep 80%, with 20% going to Microsoft. This is more favorable than Steam’s standard 70/30 split and sits between Steam and Epic’s 88/12 model. Microsoft does not publicly specify whether this rate improves at higher sales thresholds. Game Pass payouts for developers operate on a separate engagement-based model (hours played) rather than the standard per-sale revenue split.
Can I run Steam and Xbox App simultaneously?
Yes, both clients run simultaneously on Windows 10 and Windows 11 without conflicts. The Xbox Game Bar (Win+G shortcut) works as an overlay on top of Steam games, giving you access to Xbox social features, party chat, and performance monitoring while playing any game through any launcher. Most PC gamers run both clients in this configuration–Steam as primary library, Xbox App for Game Pass access and Xbox Live social features.
Will Project Helix make this comparison obsolete?
Potentially, for the console-PC crossover segment. If Microsoft’s next Xbox (Project Helix) launches in 2027 as reported–running both Xbox OS and Windows with full Steam support–it would collapse the Steam vs. Microsoft Store dichotomy for console players who also want PC gaming. PC-first gamers are likely to continue using Steam as their primary platform regardless of Project Helix, since Steam’s library, community features, and developer ecosystem won’t migrate to a new hardware-defined platform automatically.
