>>31951113GoD refined near everything. There was a greater variance in Pokemon available, straight up more Shadow Pokemon available, purifying is piss-easy now, each purified Pokemon gets exclusive event moves, a whole bunch of minigames, and the Johto starters. And more colosseums in the story.
The only thing Colosseum has that GoD doesn't is the GBA link Mt. Battle challenge, which is a damn shame because it's a ton of fun. Oh, and the Under, but eh.
