I don't know what this game is like for the other two platforms, but on Xbox, it's a tad confusing.  The game gets away with this by giving you control of three characters at once and dividing the characters up into four different teams--Team Sonic, Team Dark, Team Rose, and Team Chaotix. Each team member has his or her own strengths, and your abilities as a team change depending on which character you have set as the team leader.  The inclusion of the four different teams, however, seems a bit pointless since the game is virtually identical for all four of the teams, save for some different story elements in between levels. To be blunt, no one cares about these peripheral characters that Sonic Team seems hell-bent on pushing on gamers. People play Sonic games to play as Sonic the Hedgehog.
Unfortunately, the game suffers from a problematic, finicky camera, occasionally spastic controls, and some bad clipping.  The level designs are pretty straightforward, though you'll occasionally find portions that aren't entirely intuitive. Moreover, it's likely that you'll find yourself plummeting into a bottomless nothing without any idea of what you did wrong more than once.  This is a rental, for sure.
