Sonic Adventure 2 Dreamcast

While the first Sonic Adventure encouraged lots of role-playing and exploration, this sequel features a stronger focus on the high-speed action that is a cornerstone of the Sonic games. There are still important opportunities for character development and interaction, however. Sonic gets advice from little robot ~chaos found in different places around the levels. He gains bonus points for performing particularly impressive tricks and these can be used to unlock special secrets.

The hurried hedgehog is joined by some of his old friends in Sonic Adventure 2. Knuckles shows up to offer his spunky brand of action and attitude. The nefarious and enduring Dr. Robotnik makes an appearance too, but the real villain in this adventure may be its newest character; a dark, mysterious hedgehog whose speed and abilities might even rival those of Sonic himself. ~ T.J.
