I reeeeeeeealy enjoyed SSX 3 (that's the one before the one with Mario in it right?). This one looks like it's got great potential. I wanna board down Everest and Kilimanjaro in races, trick modes, and the new "survival" mode with avalanches and stuff!
And the social aspects of online, like global events with up to 100,000 participents submitting runs, plus the Autolog-like feature they'll add. IDK, looks sweet.
