Steam games that disclose generative AI usage sell up to 53% fewer copies than comparable titles that don’t, according to data analyzed by TechPowerUp.
The sales penalty varies by how AI is used:
- AI-generated text content — 53% fewer sales, the steepest drop
- AI-generated art/visual assets — roughly 34% fewer sales
- AI used during development (as a tool, not for final assets) — smaller but still measurable penalty
These numbers come from Steam’s disclosure system, which Valve introduced in 2024 requiring developers to label AI-generated content in their games. The dataset compares disclosed-AI titles against non-AI titles controlling for genre, price, and other factors.
The pattern is clear: players treat the AI label as a quality signal — and not a positive one. Text takes the hardest hit, likely because AI-generated writing is the easiest for players to spot and the most associated with low-effort asset flips. Art sits in the middle. Even “AI as a dev tool” carries a penalty, suggesting the stigma extends beyond the final product to the process itself.
This matters for indie developers weighing whether to use AI tools for asset generation. The cost savings from AI art or AI writing may not offset the sales hit from disclosure — and skipping disclosure risks a Valve policy violation.
NOTE
Steam’s AI disclosure is mandatory. Developers who fail to disclose face potential delisting. The sales penalty is specifically tied to disclosed AI usage — there’s no clean data on undisclosed AI use, by definition.
The practical math is brutal for small studios. A 34-53% sales reduction on a game that might sell 5,000-10,000 copies turns a marginal project into a loss. Developers using AI tools for prototyping or internal workflows should weigh whether that usage triggers Steam’s disclosure requirements — and price the sales penalty into their projections if it does.
