Great over-the-top snowboarding!
I'll go by this point-by-point:
GRAPHICS: Decent graphics, nothing too amazing, not really a huge improvement when you compare it to SSX 3, though the game has some nice effects like a speed-blur when you are using turbo. It's logical that the graphics aren't super impressive, since they had to create a whole mountain for you to ski/snowboard down on.
SOUND: Great soundtrack which has something for everyone, you can create an own playlist by picking the songs that you like, eg only lounge-songs or only r&b-songs. The game has a nice variety between songs, they have everything, from great rock-songs to lounge-songs. Also a nice effect: when you have a nice high jump, the sound dimms and you hear the wind shooting by.
GAMEPLAY: Easy to pick up and play, easy to learn controls. However sometimes the controls seem a little too sluggish eg. when you try to grind a bar you often find yourself jumping past it or grinding it upsidedown (!).
REPLAY: The Tour-mode (career) is basicly the same whether you choose a skieer or a snowboarder, of course you can try and get every objective, but it's not really that rewarding since there is no big variety between them, basicly there are a few types of objectives like: Stay off the snow, get as many air as possible, win a trick-challenge, win a race and stuff like that. It really gets repetive easily.
OVERALL: This is a fun game that is worth buying, especially with EA dropping the price to 30 dollars.
