Sonic Rivals

Sonic Rivals is a game in the Sonic series, developed by Backbone Entertainment exclusively for the PlayStation Portable. This is the first Sonic game to be developed by a Canadian company, and the first to be released on the PSP.

It features 2.5D gameplay, as players scramble to reach the end of a level before the other players do (whether they are computer-controlled or live opponents). It otherwise plays very much like the older titles in the series.

Coming in the holiday of 2007, Sonic Rivals 2 will be released for PSP, featuring Tails, Espio and Rouge, 150 more collectable cards, and new play modes.
