Query: great!!

this game is great if you already have diamond or pearl. but if you don`t it`s pretty hard to get around losing.you would like it if you like battles, thats all you do. it has great graphics but gets a little boring if your are not upgrading your pokemon or beat it but wifi match`s are always fun. i think they need a spectator or something. you need a strategy (because they are real peaple.)
