I don't get SSX3. I recently bought it cheap for the Cube. I just want to race, but it won't let me.
It took me some hours to discover that I have to board around, looking for stuff to do... And some stuff will let me unlock more courses...
Also, I think the gameplay isn't half as good as in 1080° Avalanche. I keep bumping into stuff and even when I recover by button-mashing B, I still lose my speed. I can't figure out if holding A (jump) makes me go faster.
One thing that put a smile on my face is that it also has the song Good Times from Finger Eleven, just like Avalanche.
Edit: ketchup is amazing. I'm drinking my water from a Heinz Hot Ketchup bottle.
