Sonic Riders: Zero Gravity

Zero Gravity brings back Sonic the Hedgehog and friends to the world of high speed air board racing. The original saw a release towards the end of the GameCube's life, aiming to bring a little tingle to Sonic's world and despite introducing something new to the franchise it lacked refinement: control was loose, the learning curve incredibly sharp and computers cheating more than a student at a brothel. With the success of the Wii, and the continued strengths of Sony's Playstation 2, Sega decided to take another risk with a sequel.

The concept is simple: it's a racing game and you hurtle around a blend of futuristic, fantasy worlds on your hover board, performing snow-boarding-inspired tricks to earn boost points, collecting rings and trying to overcome your foes

 

Gravity also comes into play in some interesting ways to heat up the default racing styles. Players can defy physics by stopping in mid space to take sharp turns at 90 degrees, fly along certain walls for shortcuts and with the flick of the wrist (or shoulder button) can launch into an impressive-looking gravity boost that sends you literally flying high above others for a few moments
