Not really the whole world, but I'd love to live in Keterburg from Tales of the Abyss. The snowy world and stuff is pretty. Plus there's a casino and I got really, really good at the poker game. Seriously I wasted a lot of time in the casino in the game. That whole world is nice though. I could see myself sightseeing in Grand Chokmah or playing the balloon game in Batical.
