Oh, soz for replying back late once again. xD
Well, my big brother owned a Genesis back in the days with Sonic 1 and 2 and he gave it to me later on. And as soon as I saw a picture of Sonic on a Dreamcast game (Sonic Adventure), I just knew, I needed to have it lol And yea, then Sonic Adventure 2 followed a bit later as well. To be honest I havent played Sonic Unleashed or Sonic 06 since I neither have a PS3 nor a XBox360 but played the games for Wii and DS.
