I don't know if anyone else feels this way, but the mountain needs to be bigger, yes it's a little late to bring it up for sure but I can get to the bottom of the mountain in like 3 minutes, that's what like 1000 feet vertical? I'm probably off on that but the thing I enjoyed about ssx was that it took over 20 minutes to hit the bottom of the hill, sure it wasn't free roam, but if it was that would have been sick.
Think of all the hidden areas you could stash in that much space, hidden tree jibs or snow covered dh trails. You could stubble upon a back country jump and so on. I just feel that it is way too fast a transition to be out of the big mountain stuff and be in the park.
It's a lot of work but I would enjoy one face of a mountain that was insanely long over an entire mountain, maybe it's just me but I dislike respawning every couple of minutes.
