I've played it a couple of hours now. Really feels like SSX3 to me which is a good thing. They give you two drops, one race and one trick. The game plays very fast which took some getting used to as I haven't played a game like this for years now. Still an absolute blast to build up speed and throw down a good combo. The online also sounds like it could be a lot of fun. But yeah, plays like SSX to me and I'm loving it. I'll be picking it up day one.
Sucks that the full game won't have splitscreen though.
