That’s a cool idea.
I don’t know how to upload self made characters but if there was a sort of like “customize character” workshop option where game makers could mix and match pre-made head shapes, skin color, hair style/color, clothing, etc. for there own character that would open up possibilities for many more characters. Millions of different combinations. \(^O^)
Yeah, that would be cool at some point in life… (^_^)
