A great addition to the collections of Pokemon fans; buy it for the mayhem of multiplayer battles.
Naturally, the story isn't the best; the basic plot is the same as Pokemon Colosseum. But I still like this one better because I found it slightly less difficult and much funnier. A group of bad guys called the Hexagon Brothers have a silly enough theme song, but when they count each other wrong it's downright hilarious. I makes me laugh every time.
The graphics have improved tremendously over Colosseum, with the moves looking so incredible. Unfortunately, there isn't a single-player battle mode where you fight through the coloseums ala Pokemon Stadium. It more than makes up for it with what truly shines: the multiplayer mode.
For the first time, you can pick the arena you battle on instead of fighting on the same place over and over. Provided that you have a good bunch of friends who have Game Boy Advances and a GBA Pokemon game, you'll really get a kick out of battling your friends in single, double, or multi-battles.
Overall, Pokemon XD has a solid single player mode and an incredibly fun multiplayer mode. Pokemon fans ought to check it out, since its one of only two ways to add a Lugia to your team. How do you purify the mascot, Shadow Lugia? Its a secret, but purifying Shadow Pokemon a toying with the Purify Chamber is the key.
