It's too hard and there's not enough to do.
Since I'm usually not so criticial of games I thought I'd tell you a bit about it. There's about 8 boarders and 8 levels, you start with 4 characters and 1 level. There's a free race, trick level thing, and a world circuit. I personally hate the trick level part the most because I can not land a trick for god knows what. The racing isn't that bad, but every once in a while your jump isn't big enough and you land face first one foot ahead of you. I'm not a big fan of the gameplay. Technically the game does great though. It had really good graphics for a playstation 2 launch title, although it does have the most boring menu screen ever...and the sound is alright too although the announcer gets annoying.
If you like really challenging games, or snowboarding I think you should buy this, but if not then stay away from it. Even if it is for cheap.
