Update number 1: (3/5/2012) After playing it a few more days to continue my review, this game just keeps on giving me awesome replay value. First off, when -all- of your friends are offline, you can race their ghost and try to beat their high score, race time, and survive it meters.
My recommendation : Stick with 1 of your favorite snowboarders because you can get amazing experience points and everything with 1 person. If you skip around with different people, you won't level up for certain globe areas.
The best race option in my opinion is, is "survive it". It puts you on a corse where you have to survive it, huge jumps, big cliff drops, AVALANCHES, etc. Even on some you have to have oxygen tanks (Mt Fuji). There are different types of survive it, type 1 and 2. Type one is extremely fast paced in your normal 3rd person view. Type 2 is the hardest and it's set in a opposite facing panned out 3rd person view that's kind of wonky at first. But you definitely get used to it.
Will update later with more information, again, I wouldn't listen to the 1 star reviews, seem like trolls to me.
Bought the game yesterday and it's honestly the most fun game I have played on this current gen consoles. This is exactly what this generation was missing, an arcade-like, super fun snow boarding game.
You can customize everything, there are loads of maps to play on, there is online multiplayer, challenge friends scores, all sorts of goodies that everyone likes.
It's exceedingly easy to play, not one hiccup with controls, you can customize the controls to your liking. What I did was just made the controls similar to Tony Hawk style of controls so I could sort of already be used to the design.
My rating would easily be a 9+/10, it's just too fun not to rate otherwise. It seems like people need to do their research before they spend 60 dollars on a videogame, it's not really the games fault that you can't read, it's your fault.
