'Because people want to play as themselves, you stupid fuck'

Actually, this isn't even true, IMO. I don't think I'm that unique in not caring much about what I'm playing as as long as it's a game that I like. I've played countless games with main characters that are people, animals, aliens, gods, vehicles, objects, plants, robots, whatever. I don't care.

But if a game has a character creator, I'm just going to make myself. I'm not that interested in "being" someone/something else.
