Ah, I've always dreamed and had random counter-productive thoughts of creating a grand and epic pokemon hack. But alas, I'm too lazy and/or too concentrated on school work, studies and my out-of-my-room life. :-P
But anyways, In my idea for a hack, your trainer would be an adult and the region would be modeled after St. Louis County and City. (much like how Kanto and Johto are modeled after Japanese prefectures, Hoenn after Kyushu and Sinnoh is modeled after Hokkaido)
