If you liked the old SSX games, you'd be crazy not to play this one.
What sticks out - good:
SSX is completely integrated with Xbox Live. Players can compete against each other on any of the game's 152 slopes real-time, which adds a nice deal of replay-ability. Also, the addition of gadgets to aid in traversing the many deadly descents makes for a very intense and fun time.
What sticks out - bad:
Simply two things. Lack of customization of your characters, and the annoying 'attachment physics' for grinding pipes - it's like your board has a super magnet on it.
I love SSX and this newest installment is one of the most fun games I've played in a long time. 9/10
