Sonic Free Riders happened in 360.

sonic riders: free riders
Sonic riders, Sonic Riders: Zero Gravity and Sonic Free Riders already exist.
Sonic Free Riders is the third instalment.
Sonic Riders Extreme is an unconfirmed game at this stage.
Sonic Free Riders was created on 2010-11-04.
Maybe if sonic free riders gets good results sega will continue making the series.
There has already been a Sonic Riders 3. It's called Sonic Free Riders.
It is not known as of yet if there will be another game in the Sonic Riders series.
He's not in the original Sonic riders or the 2nd one, but he IS in Free Riders. I hope this helped!
