Been playing the beta for a bit (you can just get it from Steam right now). It's .. OK I think. It's great how much of the mountain is accessible but something about the riding feels a bit off. It doesn't really feel like snowboarding, to be honest. The snow feels kind of sticky and it's not as fluid as in real life. Just general stuff as well .. you start rotations and flips after you pop, no prewind at all. You can ride in for a back 5 and change it into a barrel roll at the last second, feels kind of weird.
If they improve on that (and we get more than 2 grabs...) it could be really cool.
