If you are a fan of the Genesis this game is a major recommendation.
I only played Sonic 2 on my genesis I never had 1 or 3, but thanks to this game I played Sonic 1 and 3 and they were great games just like 2, I never beat any of them but I enjoyed playing all of them.
One of the reasons I played this game was for trophies but not as much anymore I play the games on this for fun, I never got around platnuming the game because of its difficulty for me, some people probably have platinumed the game.
Most of the games on the disc are games I never played or never heard of, the games I have heard of like, alex kid, altered beast, the Sonic games, Ecco the dolphin, The phantasy star games, streets of rage, and Vectorman, I liked all of the games on this disc, and it was actually worth it.
If it wasn't for this game I wouldn't have played alex kid or streets of rage, but thanks to this game I have played those games and I am glad I bought it.
Any ways in all honesty this game is an Great game and I recommend it to Sonic fans or Genesis fans.
