From Planet Gamecube:
Sonic Adventure DX
Sonic Adventure was Sonic the Hedgehog's first 3D game on Dreamcast, a pretty major event. Combining speedy platform gaming with exploration with characater-interaction, Sonic Adventure allowed you to play as Sonic and his many friends in a game that was simply huge. As of yet, there are no details on if/how much the game will be updated for the GameCube.
