Square Enix Details In-House 3D Generative AI at CEDEC 2026
At the CEDEC 2026 conference (held July 22–24, reported September 1), Square Enix engineers presented "Full Scratch 3D Generation AI," a system trained exclusively on the company’s proprietary assets rather than public datasets. This approach aims to mitigate copyright risks and ensure style consistency with existing IPs like Final Fantasy and Dragon Quest. The disclosure highlights a growing trend among major publishers to build closed-loop AI pipelines for asset generation.
Steam AI Disclosure Rates Accelerate to 40% in Weekly Cohorts
New analysis from Tech-Insider (published late August/early September) indicates that while the cumulative AI disclosure rate on Steam sits around 20%, the rate for new weekly releases is significantly higher. Data cited from PCGuia shows that 40% of games launched on a single week in June 2026 disclosed generative AI use. This suggests that indie and mid-tier developers are adopting AI tools much faster than the historical average of the entire Steam catalog.
Hollywood Voice Actors Clash Over AI Clones Ahead of Game Contracts
The Los Angeles Times reported on August 27 that Hollywood voice actors are intensifying their conflict with studios over AI voice cloning. While the SAG-AFTRA video game strike ended in July 2025 with new protections, this renewed focus on "voice clones" in broader media threatens to spill over into game development negotiations. Studios are increasingly testing AI-generated voices for NPC barks and background chatter, raising concerns about contract loopholes.
Local view
Japan: CEDEC 2026 Highlights Practical AI Integration Japanese industry outlet GameBusiness.jp focused heavily on the practical applications of AI shown at CEDEC 2026. Beyond Square Enix’s 3D tools, sessions covered how generative AI is being used to streamline design documents and code assistance. The local narrative emphasizes "efficiency" and "internal asset safety" over the disruptive "AI-generated content" narratives seen in Western media.
China: World Models and "AI-Native" Games Phoenix Tech (ifeng.com) profiled a startup that raised 3 billion RMB to develop "world models" capable of generating playable game worlds from natural language prompts. The article quotes developers stating that "without 3D native intelligence, true world models are impossible," reflecting China’s aggressive push into high-end generative game tech despite regulatory scrutiny.
Context & numbers
- Disclosure Volume: By the end of 2025, 4,311 Steam games carried AI disclosures. Analysts project this number will exceed 7,000 by the end of 2026.
- Developer Sentiment: The GDC 2026 State of the Game Industry report notes that 36% of professionals use personal generative AI tools, but 30% now view it as a net negative for the industry, a 12-point increase in negativity compared to previous years.
- Release Pace: Over 13,359 new titles launched on Steam by mid-July 2026, suggesting the total count for 2026 will significantly outpace 2025's 21,382, driven partly by lower barriers to entry via AI tools.
On the radar
- SIE State of Play Japan: Sony Interactive Entertainment will host a "State of Play" followed by a "Japan Day" broadcast on September 3, 2026. Watch for announcements regarding AI usage in upcoming Japanese titles, particularly from Square Enix and Capcom.
- Epic Games Policy Shift: With Epic Games Store still lacking an equivalent to Steam’s mandatory AI disclosure rule, rumors persist that they may introduce a voluntary badge system later this year to compete with Valve’s transparency standard.
