Does inventing my own universe count?
I have a universe I am creating for an elaborate story series. I've been working on this project for several years. It is called the Aelita universe and it is inhabited primarily by anthropomorphic canines and dragons and basically mixes the idealism of Star Trek with some more fantasy and less space. I realize this sounds pretty stupid, but that would be my place to exist. I just don't really want to be human.
If I have to chose someone else's universe though... it would be Solatorobo! That actually comes kind of close to Aelita and I still don't have to be human. :3 Also, I really love the whole hunter thing, making money just by doing random tasks that people lay out for you.
EDIT: Oh and speaking of Star Trek! I wouldn't mind being in that one either. I'd prefer to be an alien, but I wouldn't mind being a human from Earth. I think I'd fit in well in the future.
