Pioneer 2, as mentioned before, of Phantasy Star Online would be nice, because you could have dangerous action and in case you'd die, there would always be a respawn on your Pioneer spaceship.
Even though I love Final Fantasy VII, i don't think i would enjoy the dystopian world. Just imagine you're living in the slums of Midgar!
Morrowind on the other side could be great fun. Mainly because in contrary to Oblivion you still have the ability to fly.
Other games i'd like to live in: Zelda (OoT more than WindWaker), Pokemon, Mario Kart (if i am allowed to actually drive), ToeJam and Earl, Pilotwings 64 (with a JetPac)
Other games i would not like to live in: Gears of War, Worms, Halo, Donkey Kong Country, Resident Evil/House of the Dead/most other zombiegames, Lemmings as a Lemming
bizarre-galaxy.de - My Browsergame, but sadly only in german :(
You can play as an octopus, though!
