what about mother/earthbound?
that game is basically south park the rpg, minus the crass humor, plus tons of heart.
(ie its about 4 normal kids who uses yo-yo's and baseball bats etc to ward off weird goings on after a ufo crashes in their small town, they get money from their parents to buy new gear from the local stores, fight neighborhood bullies, deal with new threats like ghosts and zombies, learn magic from an alien, etc etc)
