Where do you want to live?
Stargate
Serenity
Eureka [which, according to Greg, and I agree, is likely part of Stargate]
Potterverse [with magic because without would be where we all are now]
Shire
[I'm skipping Trigunverse and Hyrule because they aren't as universal to us all.]
Or more? Comment and I'll add them to the list.
