I played 1080 and well, I was impressed(despite low expetations), but I think SSX3 is way better. Especialy if you have friends to play with or a PS2 online adapter(for the ps2 version). But SSX, has awesome levels.
If you like halpipe it has that. Trick runs, it has it. Racing it has it. Backcountry, it has it(remember untracked form ssx and ssx tricky?, this has even better ones). Plus it rocks!!! So many collectibles, but I don't want to spoil it. It rocks!!!!!!!!
