Sonic Riders: Zero Gravity tries to inject fresh energy into the extreme racing formula with its gravity-bending mechanics. You'll race on tracks that twist and turn, using gravity shifts to navigate walls and ceilings. While the concept is promising, the execution falls short. The controls often feel imprecise, the courses sometimes lack visual clarity, and the overall sense of speed is underwhelming. Still, there's some fleeting fun to be found in mastering gravity tricks and shortcuts, but ultimately it's a niche experience in the Sonic racing repertoire.
