I am still waiting for a better snowboarding game...
I know a lot of snowboarding games for many platforms, but none of the others are so fun to play than 1080º for the N64!
It's fast, it responds to commands pretty well, the scenarios are beautiful, the interaction is great for a "go down the hill" game, the characters have personality, the tricks are simple to make, etc, etc, etc. There's a lot of good stuff in this game!
It may be a bit late for some, but for those who have the opportunity to play and to know this game, give it a try, and I guarantee there'll be fun for sure!
