Heh, I suppose I could throw Gem a bone since we threadjacked his thread.
Honestly, mine are silly. I'd love to go to Narnia (from the original C.S. Lewis books). Talking animals. Goddamn talking animals! I want a talking animal as my best friend, and it would even be cool to meet Jesus Lion (especially if he still sounded like Liam Neeson!) But I'd also want to be there during the "golden age", when the four Children of Adam and Daughters of Eve rule peacefully and everyone is happy. Because there's no way I'd survive that nonsense with the White Witch. I'd be a statue for sure.
Also, I'd love to move to Xanth. The books went from interesting to progressively silly, and yes, I'm aware that Anthony got increasingly pervy as the years went on, and I'm also (now) aware of some problematic stuff in his early books that I didn't pick up as a teen boy. But all that aside, I loved Xanth. It was super dangerous, yes, but it was just so quirky and funny, and I'd love to have a random (not super powerful, just interesting) magic talent. Obviously, I'd be a Xanth native, not a mundane.
Hmm, where else? Videogame settings we've already talked about, but though I love those settings, I wouldn't actually want to live there, because in one, Reapers are about to destroy the entire galaxy, and in the other, I'd probably get murdered in my home by some Dark Brotherhood jerk who wanted to steal all my cabbages. I adored the setting from Final Fantasy 6 (steampunk magitech!) but again, it's kind a horrific world to live in, especially after Kefka blows it up.
Oh! I'd love to live in the world of Avatar: The Last Airbender. Assuming I avoided that whole pesky genocide thing, I'd totally be an Airbender, because I prefer not to hurt people if I can, and Aang makes it look so amazingly fun.
EDIT: And to Lanko ... yup, I think the Indoctrination theory was cool. But it's too dark for me. I want my Shepherd to save the galaxy at a high price (and that is, indeed, what happened, despite the Star Child nonsense).
