01What happened

The story, straight

More than 300 games launched on Steam in the week prior to June 15, 2026, and 120 of them — roughly 40% — included AI disclosures, according to PC Gamer's weekly Steam roundup. The disclosures are part of Valve's policy requiring developers to flag AI-generated content. One example cited: a visual novel released May 11 for $100 that disclosed 'all images used in the game were AI-generated.'

Steam dropped over 300 games last week and 120 of them — about 40% — had AI disclosures. Valve's been requiring devs to flag AI-generated content since 2024. One $100 visual novel from May 11 straight up said every image in the game was AI-generated.

  • Valve requires developers to disclose AI-generated content on Steam.
Disputed
  • The exact breakdown of which categories (visual novels, indie, etc.) accounted for the majority of AI disclosures.
  • Whether the 40% disclosure rate represents a sustained trend or a weekly spike.

05Why it matters

The editorial take

The data point — nearly half of a week's Steam releases disclosing AI use — signals how normalized generative AI has become in game development. It raises ongoing questions about quality thresholds, consumer transparency, and whether platform disclosure policies are keeping pace with adoption rates. For developers and players, the volume suggests AI tools are no longer edge cases but a mainstream part of the indie and mid-tier pipeline.

Almost half the games on Steam last week used AI and said so. The disclosure policy was supposed to help players make informed choices, but at this volume it's starting to feel like background noise. The real question is whether anyone's actually reading these flags before they hit 'add to cart.'
