I'm a Pokemon Trainer, I don't live anywhere. lolz.
Well, actually, for Johto, I'd live in.. Cinnabar Island, cause I love Blaine, and fire type Pokemon. For Kanto, I'd live in.. well.. I'm not sure actually. I don't really remember the other cities from the newer games, due to lack of attention span, but I'll take a look now that you've mentioned it.
