I decided I prefer non-AI generated art. When I look at much of the art that pre-exists, I enjoy them. I like that they're community created. I'd rather see people like Sael and Niharia whip up more stuff especially for shiny and/or alternate art. I like the eclectic mix of art styles. This is a non-commercial game and it feels odd to have commercial looking art floating around; might feel some expect the art standard to elevate to that; instead, I prefer the 'folky' level. However, I also have no problem whatsoever if AI art is included and shared. I'm stating a preference.
Edit: It might not even be 'AI' art and instead 'commercial looking' that I less prefer. If AI-created can be stylized in a less polished manner, perhaps it would feel right.
