I recently started experimenting with creating games using coding agents such as CC and Codex. What I found worked very well is if you take the pre-made assets (sprites, tilemaps, sounds) and then create a spec/harness together with game engine documentation, Codex (or CC) will do a great job in putting it all together - even play-testing the game for you.
Then I thought...why not take it even further? Create game assets as well!
And here my little project was born - "AI Game Studio". Currently it only supports sprite sheet creation, but I will evolve it into a full-fledged game studio.
I don't want to replace game designers - I've been following many for years and the art and craft to what they do is incredible. The idea here is simple - if you are a small indie developer, you could use a tool such as this to rapidly prototype some concepts before deciding on a direction. Or, you can create a basic/skeleton assets and enhance them manually.
The project uses Grok/xAI - simply because I tried over a dozen different models - from WAN to Seedance - local and API based - and Grok Imagine is the only one that was able to produce good quality results, consistently.
I would love for you to try this out, and leave comments and constructive feedback.
