First off, I've been a Sonic fan for 5 years. I've played Sonic Heros, Sonic 1, 2, 3, Sonic and Knuckles, Sonic Chaos, Sonic Blast, Sonic Labyrinth, Sonic 3D Blast, Sonic Drift, Dr. Robotnik's MBM, Shadow the Hedgehog, Sonic Unleashed, Sonic Colors, Sonic Generations, Sonic Rush, Sonic Dash, and Sonic CD. I've also played this game, Sonic Adventure. This game was the best selling game on the Dreamcast. I definetely see why. Great camera angles, great platforming, great speed, great graphics, good voice acting, acceptional cut-scenes, it's perfect. If you want a great 3D Sonic game, get this one. It's also on Gamecube, Xbox Live Marketplace and Playstation Network Store. I don't care what you get it on, just get it. It's certainly a 5 out of 5, 10 out of 10 golden game I'm not as big a Sonic fan as I was in the past, but I certainly love this game no matter what.
