Zero Gravity provides no excitement whatsoever.
The plot opens up as shooting stars crash on the planet. The next day, Team Sonic heard about the news. Soon after, they were attacked by robots, but they just barely escaped. They later find out that the robots are after the meteorites that fell from the sky, now it is up to Sonic and friends to gather meteorites! Of course, the storyline evolves, but the plot develops into an even more lame and mediocre plot. Like the first game, after you beat the Hero Mode, a new mode becomes available. The "bad-guy" mode is called Babylon Mode where you play as the Babylon Rogues . . . hooray. It won't take you long to beat both of the modes. There isn't much to do after you beat them, other than the excepted unlockable characters.
We haven't even reached the bad part of the game. The controls are some of the worst controls for any racing game to hit the PlayStation Two and Wii today. They are sloppy and difficult to control. The game's AI can be very cheap, other times it can be very dumb. The game isn't balanced out too well, and it lacks the excitement its predecessor carries. Sonic Riders: Zero Gravity isn't worth your time or money. The only people who could possibly like this game are the ones that have a terrible taste in video games, or the ones that feel bad for Sonic, and force themselves to like it.
