Vortex Effect: I never owned a SEGA Dreamcast, so I get to come into this review with no nostalgia whatsoever for what Sonic Adventure 2 was originally like over a decade ago on the Dreamcast. Nor, prior to this, have I ever played a 3D Sonic game that I actually enjoyed (and I loved the first three Sonic games on the Genesis, with Sonic 2 being my favorite one). So when I sat down to play Sonic Adventure 2 HD I had no idea what to expect and my expectations weren’t too high given my feelings towards 3D Sonic games. On one hand, my expectations were exceeded. On the other, they were disappointingly met.
