My favorite is Sonic Adventure 2: Battle...best one out there! But, yah, Sonic the hedgehog 2 was kewl with the whole super sonic thing...it's my favorite old one.
I have all the games for gamecube (Mega Collection, Gem Collection, Riders, Heroes, Sonic Adventure 2: Battle, Sonic Adventure DX, and Shadow the hedgehog). I hope to get the new Sonic the Hedgehog soon.
sonic 2 was prob the best. it introduced the spin move, and when u get all the emeralds and get 50 rings u go all super. although also the 3rd one mixed with the sonic and knuckles game cartridge was pretty cool too! it went into both games.
