Argh, Sonic died after it hit the Gamecube. I loving loved the version for the Dreamcast, which I'm pissed I can't find either one of them (Dreamcast or the game ;-;).
Heck no.
On the gamecube, they had Sonic Adventure 2 Battle and Sonic Adventure DX, re-releases of the two versions, with the graphics polished a little and some new functionality.
I remember using the Chao garden and the gamecube - Game boy advance cable to get the tiny chao garden on my GBA, so i could take care of my chao while i was away :D
Personally Sonic went noticably downhill after Sonic Heroes and Shadow the Hedgehog :(
