Of all the spin-off games I've played, I think they're all pretty okay-to-dreadful (I haven't tried Mystery Dungeon or Rescue Team, but I don't really intend to). However, there was one that I thought was great, at least when I first played it back when: PokéMon Snap!
Perhaps it's my growing interest in photography. Wouldn't it be great if Nintendo and Game Freak cranked out an excellent sequel to this game? It was so addicting and fun... I'd love to have a Generation-IV update for Wii. What do you all think? And is it a realistic fantasy, might they ever consider it? Or is there a way to at least submit a suggestion...?
