You mold your character. You play with them in their own world etc. You have to eat, get your hair cut, tatoos, bling, clothes etc. If you dont see the correlation then i dont know what to tell you to get you to understand.
I mean do you really think a little white/asian or w/e kid besides a black one knows the physics of an afro or even what it feels like? To them its just kool to give their character a fro for the looks and because its something they dont have any idea about. Like a tomagachi, you dont really know wtf it is, nor do you live in its universe so its just kool to customize your character etc.
Perhaps im not being clear but its just a thought that had came to mind at the time.
