I have it:
Pros:
Got the Target Limited which has an extra Mountain
Mountains are Huge
Good combination of natural and man-made features
Cons:
Not enough pipe terrain. I like the mad sessions you can put together in a pipe.
Some challenges
require multi-player and you can't do the best challenges until you've medal'd in all of them
It's a little too challenging. Maybe I suck but I scratch my head at some of the scores you have to get to achieve 4 medals.
My board, bindings, and boots are not in the game

Storyline is lame and unfun
The single player is a waste of time if you ask me. The multi-player is really where it's at but none of my snowboarding friends are big gamers and my gaming friends are not big snowboarders. Should've rented it first.
