Yeah, Sonic the Hedgehog 2 was awesome! I also liked Sonic the Hedgehog, and Sonic the Hedgehog 3. Sonic and Knuckles was okay. Didn't have that same charm that the first three had. Sonic Adventure for the Dreamcast may have been the only good 3D Sonic game. I don't know about Sonic Adventure 2. So many things I did not like about it.
