Its basically the sequel to Sonic 3, but its not sonic 4, anyway in this game you can either play as Sonic or Knuckles in an attempt to Stop Dr. Robotnik (eggman to fans who didnt know his old name used to be Robotnik) from re-building his 'death egg', its like the death star from 'star wars' but with robotnik's face, anyway, its an excellent buy for your Sega Genesis

Very good buying experience
