Epic Games CEO attacks Steam’s AI disclosure rules
Tim Sweeney, CEO of Epic Games, has intensified his criticism of Valve’s AI disclosure policies on Steam, labeling them "abhorrent" and "political statements" designed to be used against developers. Sweeney argued that forcing developers to disclose generative AI usage is "embarrassing" for Valve, positioning Epic as a vocal opponent of the transparency measures that Valve has implemented. This clash highlights the growing ideological divide between major platform holders regarding how to handle generative AI in games.
Steam Next Fest flooded with AI-generated "slop"
The October 2026 Steam Next Fest saw a massive influx of indie games utilizing generative AI, leading to community backlash and calls for a "No AI" filter. Players and critics have described the event as being plagued by low-quality "AI slop," with many demos lacking polish due to reliance on automated asset generation. Valve currently requires disclosure of AI content but has not implemented a hard filter, leaving users to navigate a flood of mixed-quality titles.
Japanese actors’ union issues AI voice guidelines
The Japan Actors Union has announced new guidelines addressing the unauthorized use of generative AI to replicate voice performances. The union emphasized that while technological advancements are inevitable, "living, breathing human expression" and respect for rights must remain central to the industry. This move aims to protect voice actors from having their likenesses and voices cloned without consent or compensation, setting a precedent for labor protections in the Asian gaming market.

miHoYo bets big on AI-driven development
Chinese gaming giant miHoYo is reportedly investing approximately 100 billion yuan (approx. $14 billion) into AI large models to reshape its game development pipeline. The company aims to integrate AI across art asset production, narrative design, and even NPC behavior, seeking to maintain its competitive edge in the global market. This massive capital commitment signals a strategic shift toward "AI-native" game creation, potentially lowering barriers to entry for competitors but also raising concerns about the homogenization of game content.
Local view
In Japan, the gaming press and industry observers are noting the impact of AI on reverse engineering communities. Game*Spark reported that a "legal" reverse engineering community is winding down activities due to the difficulty of preventing misuse of AI tools, despite acknowledging that AI can be beneficial if used correctly. This reflects a growing tension in Japan between technological adoption and the preservation of traditional development ethics and IP protections.
In China, discussions are focused on the "golden path" for small studios being blocked by AI. Industry commentary suggests that while AI lowers production costs, it also increases the visibility of large studios' resources, making it harder for small developers to break through with high-quality, unique experiences. The focus is shifting from "can we make it?" to "can we make it distinct enough to survive AI-generated content floods?"
Context & numbers
- AI Disclosure Rates: Approximately 36% of games participating in the recent Steam Next Fest carried a generative-AI disclosure, according to third-party tallies. However, Valve does not publish official aggregate data, and estimates vary, with some studies suggesting around 20% of new Steam releases overall now disclose AI usage.
- Industry Adoption: A GDC 2026 survey indicated that 52% of game studios use generative AI in production, primarily for research, brainstorming, and coding assistance.
- Sakurai’s Warning: Masahiro Sakurai, creator of Super Smash Bros., warned that the volume of Steam releases is expected to exceed 19,000 per year, with most AI-generated games likely to be unprofitable due to market saturation.
On the radar
- Steam "No AI" Filter: Community pressure is mounting for Valve to implement a dedicated "No AI" filter in the Steam store, similar to content warnings for violence or language.
- SAG-AFTRA Video Game Contract Implementation: While the strike ended in 2025, ongoing implementation of the new AI protections for voice actors continues to influence studio practices in the West.
- Epic vs. Valve Policy Divergence: Watch for further statements from Epic Games regarding their own platform's stance on AI, potentially positioning the Epic Games Store as a less restrictive alternative to Steam.
