I think, i can understand why a dev wants to use AI generated things. Some are just not good at drawing or creating characters or environments.
But it should be stated.
I sometimes have a hard time to actually know, if something is AI.
There are so many games and try to find out i get nowhere.
To me, the biggest problem is consistency. AI tends to imagine a lot of things and you may not get always the same character or environment. Perhaps this is possible, i don't know. I am very bad with AI myself.
