Where would you live, if you can live in any fictional universe? Joel Meares of Wired posted this entertaining guide to living life in 10 fictional worlds, from the hellish pit of despair that is Sodor (from Thomas the Train - my 3 year old would heartily disagree with this choice) and the most habitable place of Catan.
I'd personally pick Risa, but sadly it's not listed.
"TV". You know, where one can live in Greenwich Village New York easily and cheap, in a rather spacious apartment.
The Star Trek Universe, but in the "developed" sectors.
Any number of apparently utopian futures, but with the dystopia removed (such as you must go to Carousel when you turn 30 in Logan's Run).
