This is in order, based on where I would like to actually live:
5. Earth, in The Dragon Ball Universe. The major disadvantage would be the constant threats to the planet (Saiyans, Frieza, etc.), and the fact that only 6 or 7 people only ever get to fight the badguys. But I could still train and take part in the World Martial Arts Tournament and stuff. And I could learn to Kemehameha and stuff. Hell yeah.
4. Hyrule. 'Nuff said.
3. Middle Earth. I put this (surprisingly) low on my list because living in Middle Earth is actually quite dangerous. And none of the races really have an advantage over the others: Elves are cursed with immortality, Dwarves are greedy and obsessed with treasure, Men are easily tempted and corrupted by the Ring and other evils - and are generally less awesome - and Hobbits are freaking short and don't adventure much. So if I wound up as a
good race, none would really have an advantage. However, living in Middle Earth would be awesome in any case, considering it's like Feudal times with less disease and corruption, and more awesomesauce battles, glory, and mythical stuffs. Wow, that was long.
1. The Star Wars Universe. No planet specifically - I'd probably travel across the galaxy doing Star Wars stuff. I likely wouldn't be Force adept (but would love it if I were), and in that case I could still be some badass scoundrel shooting first like Han Solo or something. Aw yiss.
1. Hoenn, in the Pokemon Universe (Hoenn's just my favorite, but no Mewtwo...
). I'm surprised myself that I put this so high, but it does tie with Star Wars. The major advantage to living in the Pokemon Universe - no one will kill you, as long as you have Pokemon by your side. And the majority of other people in the Pokemon Universe - especially most of the bad guys - are complete idiots. So I'd be pretty safe, and could battle freaking awesome Pokemon.
I spent way too much time on this post...
