RZ Review - Sonic Adventure 2 (DC & GC)

Two and a half years after the release of Sonic Adventure in Japan, its sequel was one of the last games created by Sega to come out on the then recently cancelled Dreamcast. Even though I don't think the original is a bad game, it has many problems that it suffers from, most notably a lack of focus and direction. Have any of them been addressed for Sonic Adventure 2? Which of the two titles do I feel is better? I hope this lengthy video provides all the details.
