X2 Snowboarding is a fast-paced extreme sports simulation for the iPhone/iPod, combining console quality graphics & physics with arcade style game play.
It's a pretty cool game. I love the fact that the controls are so easy to get to grips with. My favourite feature though, is the fact that I can have whatever music I want in the background when I'm boarding down the ultimate slope :D.
I only wish I had an iPad because they are releasing a HD version for the iPad and iPhone soon.
I bought the base version initially to test it out, it was a bargain! Then I gave in and bought the full version later on.
