It's an orgasm for the ears
I have a line-in going from my TV to my computer, and HUGE headphones. I play the game with said headphones on and...wow. It's fucking awesome.
Gameplay doesn't differ too much at the core from Tricky, but there are a few new modes--including "Super Pipe", a HUGE half pipe. There's a TON of replay value (Perhaps TOO much) in unlocking every peice of clothing for every rider in the game, getting all of the collectible items and getting a gold medal in every competition.
Buy. Seriously. I just rented and I'm gonna cry when it goes back
