This game compiles the best features of the classic Sonic games, its fast, its fun, and they even brought back the pinball night zone

But this game has some other nice features to make up for the lack of levels, there are time trials, and a Virtual Pet game called Chaos Garden, the point of the game is to raise an animal named Chao by taking care of there basic needs

And i think one of the coolest features is the tiny chao garden where you raise your chao by feeding it, playing mini games with it, and if you have gamecube you can hook up your GBA to it and transfer the chao in each game to the other system and raise it

This is a great feature in Sonic Advance

Sonic Advance is pure Genesis-esque 2-D fast paced side scroller action that will keep you playing it for quite a while, even after you beat the game due to some great added features.

Many different moves and a very cool feature called the "Tiny Chao Garden
