Megastore: Tidy Up Together

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

AI tools were used to assist with some of the game’s translations and in the creation of two in-game textures. These textures were subsequently edited, refined, and carefully reviewed by a human before being included in the final game. We strictly rely on human creativity and craftsmanship throughout the game’s development.

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.
