Sega's blue mascot is back - this time on the Dreamcast. The import version of Sonic Adventure received a 9.3 on videogames.com, and there's no reason to think that the US version won't be at least as fun. Speed is the key to this 3D platformer, and the graphics were stunning. Gameplay consists of a combination of exploration and platform running and jumping and you get to play as both Sonic and Knuckles. Minigames abounds as well. This is a Dreamcast launch title and will be out on September 9, 1999.
