I think I'll have to throw my lot in with the other people saying 'pokemon', simply because it's pretty equal opportunity lorewise. No special powers? Not a member of the elite? No problem! You don't need to be either. Pretty much everybody in that world interacts with pokemon daily, and it's a comparatively nice world to live in.
I'd be a bit more up for that were it not for the fact that the OP specifies that you personally won't change. The MLP universe has a lot going for it in terms of comfort, opportunity, and general livability, but that presumes that you'd be one of the existing races for that world (pony, gryphon, zebra, minotaur, dragon, buffalo...). Given the premise that I'd be reborn as one of those, it'd be a pretty nice deal, but the idea of being human in a world where humans otherwise don't seem to exist...that's significantly more iffy.Katherine Kerensky said:Sue me, but I'd pick Equestria from MLP:FiM. Relatively peaceful, no tyranids, no giant monsters, peaceful neighbours that don't want to eat me. Could just do my gardening in peace and isolation. Like living out in the Styx on Earth, but less likely to have a serial killer or thief come knocking.
