Very fun game, especially for a handheld
Graphics: Strong point of game. They are awesome. The in-game movies are dvd quality and the in-game graphics would stand up against the best looking Ps1 titles.
Sound: Not overly impressive, but not bad either.
Tilt: Just a lot of fun to play. I really like playing all the different modes of play against bots, they are almost as good as playing people.
Don't listen to other people who say the single players stinks, it is actually pretty darn fun and I would recommend this title to any ds owner, with wifi or not.
