Anywhere but USA. I've had my fill of it for a while.
I would want to go to Japan to help the victims there, then to China to save a few thousand cats, Germany, Russia, France, England, Italy, Spain, Africa, India, basically a life long tour of Europe. I would like to spend some time in Canada or Panama, as well, though moving through Mexico doesn't sound to great, it's only good for the pretty water and ancient ruins in my opinion.
Real place: Japan: They keep all of the good games to themselves >: [ Fantasy: Springfield: I'd love to see Homer's antics, then laugh at him as he is insane.
I would go to...Japan (Learn Japanese), London (Learn French), Moon (To eat the cheese!), Mars (To steal some alien devices for my own "Purposes", and last, but not least HOME!
