Well not to say it isnt fun, it is but dont play it for like 10 hours strait, it will get really old fast if you do it like that. Now you go through the 2 acts per borde and a boss battle( except for the carnvial borde it has no boss battle) you must race a rival to see if you can get to eggman first, why because you have something you want to ask him end nothing else matters. You comuncate in the cut scene whit is a still image whit a few words on the screen. While you race agianst a rival you will be able to get power ups. Each power up acts in a diffrent way, for example, if you are in the lead and you grab a ligthing bolt power up you will live coins behind that will shock your rival if he touches it. But if you are behind it will atomatchially shock him. Also each chachter has their on unique power up. Sonic has a sonic boom which gives him a huge boost of speed in a blue haze fassion. while Knuckles has a power punch, where in he punches the ground and leaves the other chachter stuned for a short time. Shadow slows down time for the other chachter whit chaos control. Silver messes up your rival's screen whit his ESP, And Meatal Sonic takes your oppentes power up. They have a 152 cards for you to collecet that will unlock suits and gloves and shoes for your chachters. They also have a nastigaial factor to them, they show all from when the game started. Its nice and better than your rock collection. (your rocks suck i just had to say it, they suck.) Overall its good but it has a low replay vaule. also i'd just like to say thanks SpaceEmporor.

What I find so interesting about this game is it's long ranged storyline starting from the old,"Sonic the Hedgehog." Another thing about it is its featurres.You can dish out battle on the PSP with your friends compeating for their collectable cards.And don't get me started on the graphics.They rock for a handheld. 4.5 is what it is. :) Tolston Jordan
