There is no "I" in Team, like there is no "good voice acting" in this game.

At first glance at this game, I was amazed of how easy the gameplay is and how simple it is to pull of a team move like the Triangle Dive (why is it called 'dive' when they use it to go up?). You play as 4 teams, Team Sonic which has fast gameplay and has a 'normal' setting for average players who can play as Sonic, the annoying Tails, and the cocky Knuckles. Team Dark, which is meant for expert players, has Rouge who stumbles on Shadow who is suffering amnesia and the revenge-seeking robot, Omega. Team Rose, who is the most annoying of all the teams, has Amy, Cream, and Big looking for Froggy (oh course) and Cream's missing sidekick, Cheese, while Amy is looking for someone, who is blue and hates her guts. Finally, we have the three detectives called Team Chaotix, who would be the coolest team if they got rid of the high-pitched-voiced Charmy, who hands out with their leader, Vector, and the stealthy ninja, Espio. This game would be good, but was shot down by very few enemy models (you fight the same looking robot in every level!) and also, it would be more interesting with better voice acting. The graphics are . . . decent, but the gameplay and the music suit the game's somewhat childish features. The Chaos Emeralds are the big idea in this game, but what ripped away the enjoyment of playing in the Special Zone is the horribly designed gameplay and the most annoying controls ever that only change when you fail the mission to catch a Chaos Emerald with wings, which is about impossible with these two features. Other than all those flaws, the game itself is greatly planned and developed and the teams' ending themes are great, from the happy, childish tune for Team Rose to the dark rock-and-roll hit for Team Dark. The multiplayer on a scale of 1 to 10 is a 4. The different challenges like "Collect the Rings" and "Battle" can be annoying for both you and your friend. The three types of races (Speed Race, Intermediate Race, and Expert Race) are only different from their lengths. What really killed this game is the jet car that the team pilots. The controls on the car are sloppy and jumping only slows you down which means you are unable to make the goaled time. Personally, make the multiplayer a lot more interesting and fix everything else.
