How could this game get any better??? I mean, the original Sonic games were great, but this one tops them all.
What's neat is, you don't have to be sonic the whole game. Knuckles, Amy, and Tails are now playable. That's what got it one of the five stars.
Like Sonic Adventure and Sonic Adventure 2, you can take care of Chao in Chao gardens. This gives you something to do if you are stuck in adventure mode. There's the second star.
All you need is a link cable and some friends with a GBA to play some multiplayer. You're friends don't have to have Sonic Advance to play with you. Yep, the third star.
Sonic Advance gets it's fourth star because it can hook up to the Nintendo Gamecube game Sonic Adventure 2 Battle and trade Chao data and Chao themselvs.
The last star is for all-out game play. It's another running, jumping, spining, dashing, rolling, gliding, flying, hitting, smashing Sonic Game. How could you not like it???
