I may not owned this particular compilation. I did grew up with all three Sonic games included in it. You get the first two Sonic games on Sega Genesis. Along with them is Dr. Robotnik's Mean Bean Machine. The original Sonic may have some issues mostly Labyrinth Zone. It's still a fun platformer that holds up amazingly well. Dr. Robotnik's Mean Bean Machine is a fun puzzle game based on The Adventures of Sonic the Hedgehog show. Yes all your opponents are pulled from that cartoon show I checked. Yes this was actually an licensed localication of the game Puyo Puyo. A similar situation with Kirby's Avalanche on SNES. I will say I absolutely love the soundtrack as well as the password system. This spin off game still among my favorite Sonic games ever!!! Speaking of that, Sonic 2 always been not only my favorite Sonic game. But also my absolutely favorite Sega game I ever played!!! I absolutely loved everything about this Sonic game. It's a truly solid platformer that's still among the best platformers I ever played is truly speaking volumes of it's greatness!!! You are getting three solid Sonic games in one package what else could you possibly ask for?
