Gamespot have posted a Hands-on for the upcoming GameCube Game, Whirl Tour. Here is a snippet of the Preview:

As Whirl Tour begins, a band named Flipside is sucked off the stage in the middle of a concert and disappears into the sky. Concerned for their well-being, Wasa B., the band's roadie, sets off on his scooter to rescue them from the depths of a dark castle. The version we were allowed to play had two levels unlocked and a race mode available. At the beginning of each level, you must choose a rider and a scooter, and at the game's outset, there are just one character and one scooter to choose from. But as you defeat boss characters in the game's race mode, new characters and tricks are unlocked.

Much like in other extreme sports games, the gameplay in Whirl Tour is predominantly combo-driven. Jumping is accomplished by pressing the A button, and the longer you hold it, the higher you'll jump. You can grind and slide on ledges using the Y button or perform aerial tricks with the X button. In this way, the controls are identical to those of Tony Hawk's Pro Skater 3. While on flat ground, you can also perform slides by holding the analog stick to one side and pressing the X button. If you're in midair and see that you're going to bail on a trick, you can press the A button to save your combo points. If you're having problems with the default control scheme, you can customize it to match your abilities.
