Four teams have been invited to enter the contest, each with its own ulterior motive.

Eggman, set up in a rather poor disguise, is holding a second EX World Grand Prix tournament where the winner gets plenty of cash and treasure for his efforts. The plot for the game is a little different than what was seen in the previous games in the series.

Can Sonic's racer pull off an amazing racing experience, or is it still a mediocre title with a shiny new control scheme? This suddenly makes a once-mediocre racing title more intriguing. Sonic Free Riders acts as a sequel to the second hoverboard racing game, Sonic Riders: Zero Gravity, but this time, it does so without a traditional controller. It is the first time, however, that Sonic is being used on the Kinect for a racing experience.

It also isn't the first time Sonic has jumped on a hoverboard, as evidenced by Sonic Riders, which was released in the previous generation of consoles. He's done so on foot in Sonic R and Sonic Rivals (and the sequel), and he jumped into a go-kart against fellow Sega icons in Sonic & Sega All-Stars Racing. This isn't the first time Sonic has gone racing.
