It's supposed to be better than the Tony Hawk Pro Skater series, with innovative controls that are based on a realistic physics engine. This means that you no longer simply mash buttons to get the tricks you want, but instead have to focus on physics in order to be successful. While this approach is more difficult to learn and master, it offers the player new ways to perform tricks. The graphics also look much better.

I'd get it myself, but I don't own a PS3 or an XBox360.
