The Sonic and Tails levels are a blast,and Knuckles levels are okay, but, bigs levels are boring.
Big's levels are fishing level you heard right all you do the fish for Froggy nice name for a frog don't you think? His story is very short which is a good thing because his levels aren't that fun. Amy runs from a robot named Zero not mega man zero because the robot is trying to get the emerald the bird is carrying. As Super Sonic you go one on one with the boss of the game you may need to try a few times but, it isn't that hard for the last boss. The Chao mode is fun you can raise blue creatures that evolve based on what type of power up you give them. There are fly type, swim type. power time, and stamina type Chao. If you are a Sonic fan like a am you may want to add this game to your collection.
