OMG.......this is, like, the best game complication EVER.
Sonic, Sonic 2, Sonic 3, Sonic & Knuckles, Comix Zone, Vectorman, Dr Robotnik's Mean Bean Machine, Golden Axe Warrior, all great games.
And, I can't forget Phantasy Star. Best. RPGs. Ever. And it comes with the first four games in the series!
I would definitely recommend this. Plus, you can get some decent achievement score!
