Hatching of Gods and Demons

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

This game includes pre-generated content made with the assistance of generative AI tools during development. AI tools were used to help create and iterate some static story illustrations, character and store-art references, voice and sound-effect materials, texture details, copy polishing, and localization drafts. All such content is selected, edited, assembled, and manually reviewed by the developer before shipping. The game does not connect to a live generative AI service during play and does not generate new player-facing AI content at runtime.

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.
