I would live my early years 0-7 in Sinnoh then move to Unova from 7-21 and adventure then I would go to Hoenn for a job 21-50 constantly visiting Unova then settle down in Jhoto 50-Death with a vacation home in Kanto's Pallet Town.
Kanto would be fun, lots of Pokemon, lots of space, an old guy in the middle of the road, and Pikachu.
Unova would be fun too. Cilan <3, Big Cities with amusement parks, Zorua, and cute little Axews! But then again, that creepy Ghestis guy lives in Unova. And so does Natural. But I'll live in Unova as long as I am as far as possible from creepy guy in the snuggie and king oblivious.
