I know about Riding Star (though I haven't tried it so I don't know if it's any good), but it's korean and I imagine it requires a KSSN to register for it so unless theres some legal way around that, it's out of the question. It's basically exactly what I want though so I'm crossing my fingers that theres some way to play it (legally).

But, otherwise...

If anyone knows of any snowboarding games (even if I have to buy it) for the PC that have a decent multiplayer mode and enough people playing it, I would really appreciate your replies. :)

riding star are just the translated words from korean language. its actualy out in america and its called "project powder" and its out now!!!!!! play it now!!!!!!
