hmm....
kanto:
cerulean
it's warm ( i think), near water, has a gym, the bike, shop, bill is right down the street, and apparently ambellina is there! my first friend on pc.
johto:
azalea town.
it has a great history, and there's that kimono girl dance studio with all the eeveelutions.
hoenn:
sootopolis
it's secluded, beautiful, full of water, and wallace is there! sometimes. he's my favorite gym leader.
Sinnoh:
sunnyshore.
warm, water, energy efficient (gotta care for the environment.) and there's volkner...
fiore:
summerland
i'm sure you can see my reasoning. No? well, there's warm weather, the beach, the jungle, the temple, the rangers, and the capture challenge.
almia:
vientown/chicole village.
my partners would be right nearby and i would be near the beach, breeze hill, and the ranger school.
