I would live in Hoenn, or Sevii. Southern Island would be my first choice, while one of the islands, maybe 2 or 4 would be my second choice. I like to have a place that would be all to myself, difficult to find, isolated, and somewhat extravagant. Mt. Silver in Johto (aka Mt. Fuji in Japan) would also be pretty nice. All of the regions in Pokémon are real places in Japan. If you look at a map, you will see big similarities.
