Cue me rummaging around for my copy of arguably the DC's best looking 'boarding sim - Sega Extreme Sports. I know it's not technically a proper bonafide snowboarding game, what with all the hang-gliding and mountain biking going on, but the boarding sections are super cool (sorry), and miles better than Snow Surfers and that bit in Sonic Adventure where you have to outrun that avalanche.
Anyway, enough waffling. Here's the vid. Enjoy.
