You are right! We just rushed to bring the game to market as soon as possible.
In the meantime I created capsule art based on in-game snapshots + Canva for text. I also re-did the survey and I am now not using AI for the art at all. Still using AI for internal tools, queries about Unreal Engine, small tasks in the dev process, but this is excluded by the survey on Steam or Epic. For the 3d models I buy the models or creating them myself. AI for real models still has a lot of way to go IMHO.
