Good if you have diamond or pearl. Great online multiplayer.

If you have been reading reviews for this game, you'll notice that some are good and some are bad. There is really one factor that will completely decide if you like it or not. If you have Diamond or Pearl, it is fun. If you don't, it is completely lame. This came is really made to be compatible with D/P. It is possible to play it without D/P, but you can only use the 6 rental passes that you are provided with, and that gets boring really fast. On the other hand, if you do have the DS games, you get to use your pokemon from your DS to battle against gyms as well as real people online, which is quite fun. This game is not really comparable with pokemon stadium games for n64 though. It lacks all of the fun stuff like mini-games and gymleader castle. Plus you don't have the option to rent almost any pokemon you want for a battle. You're pretty much stuck with the ones you have. For this game, I would say if you are not a big fan of pokemon, or you don't have D/P, don't bother with this game. Otherwise, it may be worth your time.
