1930: Farm Manager Demo

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

Generative AI was used as a supporting tool during solo development, mainly to find technical information faster, compare possible solutions, check code, organize notes, and explore early ideas. It saves a lot of time that would otherwise be spent searching through browser tabs and documentation. I also use it to help with translations. The game’s design, development decisions, implementation, and final content remain entirely under my control.. The game does not generate AI content during gameplay.

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.
