Dark Summit

The Good
The different challenges are varied and (almost always) nicely balanced. The physics on the different things you can trash (snowmen, crates, barrels, signs) are great! Everything rolls and tumbles down the mountain.

The Bad
All the challenges are easy to find except for the last one. It's ridicilously well hidden. Took me hours to find! Annoying last challenge. When you complete it once you unlock a lot of characters, and when you play the game with those almost nothing changes.

The Bottom Line
You are a snowboarder who's trying to uncover the secret of Mt. Garrick. You do this by accepting different challenges, like grind this, jump that, pull this trick off. But also weird, yet fun, challenges, like destroy 20 cows, grind the turkey, and such. It's tony hawk on a snowboard, with one huge level. Addictive and fun.
