You've raced on the ground. You've raced on water and even in the air. You've even raced on huge raised tracks. RG-01 give you the chance to race over the surface of the outer hulls of vast space cruisers. Each cruiser has it's own theme, such as the vacation cruise, featuring theme parks, beach domes and artificial mountain ranges.
Despite hovering in a manner familiar to anyone who played WipeOut, your craft handles much more like a ground-based vehicle, making the learning curve much less steep thatn other anti-gravity racers.
