Epic CEO Sweeney Slams Steam's Mandatory AI Disclosure Tags

Epic Games CEO Tim Sweeney has taken another shot at Valve’s Steam platform, this time strongly condemning its mandatory artificial intelligence disclosure rules. In a recent interview with PC Gamer, the Fortnite boss called the policy "irresponsible" and a major threat to modern game developers. Sweeney argued that forcing studios to slap an AI label on their storefront pages acts as a modern-day "Scarlet Letter," instantly inviting toxic backlash and review-bombing from players that can utterly ruin a game's chance at commercial success.

"I think it's really irresponsible of Valve," Sweeney told PC Gamer while discussing the mandatory disclosures. "They shouldn't do it, because it makes it much, much, much harder for a game developer to have a chance of success." He went on to explain that these labels create a "hater community trying to kill the game," effectively punishing developers who rely on these tools to survive in a highly competitive market.

Because Steam remains the undisputed king of PC gaming storefronts, developers have no real choice but to list their games there to gain visibility. However, complying with the AI label comes at a steep cost. Recent research by Game Oracle reveals that titles carrying Steam's mandatory AI disclosure warning suffer up to 53% fewer user reviews compared to games without the label, indicating a massive drop in estimated units sold. This analysis also noted that the community backlash hits established, larger studios even harder, heavily impacting bottom lines across the entire industry.

A Redundant "Productivity Tool" for Indie Developers

However, Valve clarified that AI tools used purely for internal development efficiency, such as code helpers, do not require disclosure, framing the rule as a neutral, pro-consumer move. This is not the first time Sweeney has called out Valve over this issue. Back in 2025, he argued that Steam's AI labels were pointless because almost every game would eventually need one, making the disclosure completely redundant. 

Sweeney views AI as a crucial "productivity tool" and equalizer that allows smaller startup teams and indie studios to compete against massive, billion-dollar live-service games. He believes Valve's requirements make it nearly impossible for smaller developers to compete with industry incumbents, as per GameRant. 

During his recent interview, Sweeney was pressed on gamers' concerns that AI tools are frequently trained on other people's art and creative work without permission. He acknowledged that some AI models have been trained using unethical methods, but argued that developers are under immense pressure to find more efficient ways to make games. He further suggested that much of asset development could be optimized with AI, stating that only a fraction of that time is spent with the artist "really injecting the creativity."

Unreal Engine 6 Integration and Backlash

Epic Games is backing up Sweeney's stance by actively integrating AI into its upcoming Unreal Engine 6, but the company is already facing backlash. In a recent YouTube video showcasing how Epic uses generative AI to create in-game assets, an artist demonstrated using tools like Nano Banana to refine renders of original artwork. 

The AI noticeably altered several aspects of the final output on its own. Tools like Nano Banana have faced accusations of being trained on copyrighted material, which appears to conflict with Sweeney's criticism of AI models that rely on unethical training methods.

This clash highlights a massive divide over the future of game development as the technology becomes an industry standard. With AI firmly rooted in the production pipeline, the industry is no longer debating if the tech will be used, but whether storefront transparency tags serve as helpful consumer facts or unfair marketing penalties. 

While the response from many consumers regarding Steam's AI disclosure requirements has been largely positive, with players arguing they have a right to know what they are buying, Sweeney's recent comments make it highly unlikely that the Epic Games Store will adopt a similar policy anytime soon.
