Steam just started selling VR GAMES that will not run on a gaming PC — and Valve says that is ALLOWED. Two titles that landed with Steam Frame on September 14, Fast Travel Games’ Action Hero and Halfbrick’s The Thrill of the Fight 2, list NO Windows, Mac, or Linux builds. They run in STANDALONE mode on the headset only.

That is a quieter POLICY SHIFT than the open-sourcing of Lepton, but it is the STOREFRONT consequence of the same ANDROID path. For two decades a Steam game meant a PC GAME. Valve has now put the opposite in writing.
What the Store Pages Say
Action Hero opens in capitals: “EXCLUSIVELY ON STEAM FRAME!” Its only VR requirement is Steam Frame. Steam’s API mirrors that — platforms for Windows/Mac/Linux are all FALSE, and the minimum line is simply “VR Support: Steam Frame.” US list price is $9.99 (launch discount to $7.99 as of this writing).

The Thrill of the Fight 2 is blunter for PC VR OWNERS. The Steam description states it is Steam Frame VERIFIED with “full crossplay with Meta Quest,” then warns: “SteamVR PCVR is not yet supported — Steam Frame standalone only.” Platforms are again all FALSE. List price $19.99 (about $16.99 on discount).

Valve: No PC Target Required
In a September 15 email interview with Automaton, Valve answered the APK-ONLY question DIRECTLY: “Partners who ship on Steam have the freedom to target any platforms they think make sense for their game and audience. There is NO REQUIREMENT that a game must have a PC target.”
Mixed-News (September 18) ties that QUOTE to the two LIVE store pages and to Valve’s APK upload docs, which tell studios to tick Android and note that an Android-only app edits the default depot. Those builds run through LEPTON, Valve’s Android-on-Linux compatibility layer for SteamOS on Frame.
Why Quest Ports Land First
Valve’s own developer notes, as cited by Mixed-News, ENCOURAGE studios that already SHIPPED a mobile-optimized Arm64 Quest build to run that VERSION on Frame’s Snapdragon 8 Gen 3. Both launch titles fit the PATTERN: Action Hero shipped on Meta Quest in December 2024, and Thrill of the Fight 2 advertises Quest crossplay on Steam.
Automaton’s Nobuaki Shibuya — speaking from his own prior VR work, not as Valve — estimates more than 90% of copies of the VR games he has worked on came from Quest and under 10% from Steam. That ECONOMICS story explains why an APK-first Steam SKU can make sense even when Index and PCVR Quest owners are left out.
Who Gets Locked Out
BUYERS with a Valve INDEX, or a Quest wired or streamed to a Windows PC, can SEE these pages in the Steam store like any other VR release — and then FAIL to LAUNCH them on a PC-connected HMD. Halfbrick’s “not yet supported” wording leaves a DOOR open for SteamVR LATER. Fast Travel’s page still markets Action Hero as Frame-exclusive.
The asymmetry runs ONE WAY. Steam Frame can still STREAM the full PC LIBRARY over the included wireless path. What it adds is a SECOND catalog: Android-class VR SKUs that live on Steam but never touch a tower. With purchase emails rolling this week and no public shipping date yet, those SKUs are Steam games almost no CURRENT Steam USER can PLAY.
