It's really a let down compared to previous Stadium games.
What really annoys me about this game is that they have recycled the Pokémon animations and attacks from the N64 days and that there is no decent single player mode at all. Back on Stadium on the N64 you could at least battle all the gym leaders from R/B/Y ... I'd have loved to see that return, taking on the gym leaders of the previous games. Oh well.
Good enough to battle a friend - but the online mode is really weak too.
