Epic Games CEO Tim Sweeney has escalated his attack on Steam’s AI disclosure rules, calling Valve’s requirement that developers label generative AI content “a political act” in a run of posts on X between October 23 and October 26, 2026. He argued the labels exist mainly to fuel “cancel campaigns” against games. No public response from Valve had appeared by the time of writing.
The rule itself has not changed. Steam still asks developers to disclose AI-generated content that ships in a game or is generated while it runs. What is new is the tone: in June Sweeney called the policy irresponsible, and now he is framing it as politics.

What Tim Sweeney said about Steam’s AI disclosure
The thread started on October 23, when Sweeney replied to a post by Matt Workman that called the AI disclosure “ABSURD in 2026”. Sweeney wrote that “forcing developers to write a political statement to be used against them by the hate mob they’re helping organize is abhorrent.”
Later that day he rejected a comparison with age ratings. Those, he said, help parents make informed decisions, while “these AI statements are just as partisan as mandatory political essays or forcing developers to list their voting history.” In another reply he asked whether Valve should make developers list their political affiliation if many gamers disliked one party, and whether that would be “pro-consumer”.
The line that made headlines came late on October 25. Sweeney wrote that “the primary use of both categories of disclosures is to drive cancel campaigns against games and deprive them of revenue and livelihood,” adding: “Yes, blocking free choice to adopt productive technology is a political act.”
About an hour later, in a separate reply, he replied that “Epic has been extremely open with all developers and the general public about how we’re using AI,” pointing to Epic’s Unreal Fest talks in Chicago, Seoul and Shanghai. GamesIndustry.biz collected the posts on October 26.
What Steam’s AI disclosure rule actually requires
The “both categories” Sweeney mentions are the two parts of the generative AI section in Steam’s Content Survey, which every developer fills in before release:
| Category | What Valve asks for |
|---|---|
| Pre-Generated | Content made with AI tools during development that ships with the game, such as art, sound, narrative or localization |
| Live-Generated | Content AI creates while the game is running, plus a description of the guardrails that stop it generating illegal content |
| Not covered | AI-powered tools built into development environments. Valve says “efficiency gains” from them are “not the focus” |
Valve introduced the disclosure in 2024 and rewrote it in January 2026 to make clear that coding helpers and similar workflow tools don’t need to be listed. Whatever developers declare appears on the game’s store page under “AI Generated Content Disclosure”.

Why it matters for players and developers
This is not a new fight for Sweeney. In a June interview with PC Gamer, reported by VGC, he called the label a “Scarlet Letter” and said: “I think it’s really irresponsible of Valve.” His argument is that developers who use AI tools get punished by part of the audience, while those who avoid them fall behind competitors that don’t.
Supporters of the label see it the other way: it is often the only place a player can check how a game was made before buying. AI use is already a common cause of player backlash. Earlier this month SEGA pulled Total War: Shogun 2 Complete Edition from sale after complaints that included art players said was AI-upscaled. And the Moonlighter team delayed a public ReVamp playtest over fears of AI clones.
Epic, for its part, has been open about using AI itself, including on its new “vibe coded” Epic Games Launcher. Sweeney’s own June comments explain why Steam’s rules carry so much weight: to get a game “as widely publicized as possible,” he said, “you’ve got to put it on Steam so people can wish list it.”
What’s next
Nothing changes for players or developers unless Valve acts. The disclosure stays on Steam store pages, and Valve has kept it through criticism since 2024, adjusting only its scope. Watch for a Valve response or another revision of the Content Survey, which would show up on the Steamworks documentation page linked above.
