This is one of the worsts games I ever had played on the nintendo wii. It has good graphics, but is not the best game.
Let's start with the good things. This game has excellent graphics in each stage. Is one of the best pokemon games that has very good graphics. Is also the first game with the wi-fi system. You can exchange your pokemon''s from diamond and pearl and translate them to this game. Thats the only way to have your own pokemon, but you could use the pokemon that this game have.
Now let's talk about the bad things. First of all, this games doesn't have a common storyline like the previous games, Pokemon Colosseum and Pokemon XD Gale of Darkness had. The battle system is also very difficult. To beat a stadium or colosseum you need to have very good tactics and very good pokemon so u can manage to beat them. Without a storyline, it makes the game very bored.
I think this game is not the best in the wii system. This game could have been better if a storyline was added. Everything is difficult, opponents, colosseums, stadiums, etc. I really didn't liked it, I don't recommend to anyone, unless your a wi-fi fan. I will give a 3.5 of 10. Is not the best game.
