Sonic's appearance on the Nintendo GameCube can be considered to be an unbelievable milestone of epic proportions. But the GameCube version of Sonic Adventure 2 is very real and is currently being shown at Nintendo's Space World 2001 event. Sonic Team has been tightlipped regarding the enhancements planned for the GameCube version, but any additions should only improve a game that is already packed with a variety of gameplay options. Sonic Adventure 2 will be released on the GameCube this fall in Japan. A North American release should follow shortly.
