Space Tales

The developers describe how their game uses AI generated content like this:

All visual art, textures, and visual effects were created entirely by our human artists. All game code was written exclusively by our human Vietnamese development team. 90% of audio, including music and the majority of sound effects, was composed and produced by professional musicians and sound designers. AI tools were used to generate approximately 10% of supplementary ambient sound effects. 90% of voice acting was performed by professional voice actors. AI-generated voices were used for minor background NPCs with minimal dialogue, and for the in-game AI companion character - where an AI-generated voice was a deliberate narrative choice to represent an artificial intelligence within the game world.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
