  25. As for the spinoffs, I don't think it's fair to compare them as the amount of content/replay value is entirely different. On enjoyable level though, they all fall around the same as Emerald, and I love all the ones I've played, including the Stadiums, Snap, Pinball, Mystery Dungeon and Puzzle Challenge.
