Sonic Riders: Zero Gravity, while not nearly as good as the first game, is still very fun! Instead of drifting on your extreme gear, in this game you use the power of zero gravity to shift your direction and boost through the levels. In addition to this, boosting during certain sections will allow you to grind on certain flying objects, which is very fun to pull off! Zero Gravity is nowhere near the level of difficulty as the first game, which wouldn't really be a bad thing, if the game weren't also so short. If you enjoyed the original Sonic Riders, you may enjoy the improved graphics, more distinct skills for the character types, and even more playable characters than before, however you may also dislike how different some aspects of the racing are. I'd still recommend the game if you enjoyed Sonic Riders on GameCube!
