It's been mentioned a couple of times, but my first choice would be the Pokémon universe. Think about it: very rarely is the entire world/universe/human race threatened, and it's entirely possible for a regular person to live a regular life. Also, Pokémon. 'Nuff said.
Failing that, and because it also hasn't been mentioned, but, if could be a capsuleer, the EVE Online universe would be quite awesome. The only problem would be the chance of not being a capsuleer, in which case it'd barely be different to regular existence...
