the good : AAA Genesis title , perfect emulation , save anywhere feature make play more fun and easier , wireless be great , addition of info and hint be interesting and helpful the Bad : Games do not have any upgrade , a few dud the Genesis be the first system I ever own or play so these title and compilation be right up my alley . with the best Genesis ever make in one game be great . Games from Sonic the hedgehog 2 to Ristar to Vectorman . what be best about this be not just the game but the layout and feature . most game feature wireless multiplayer and the ability to swap score . also , each game have a museum feature to view box shot , hint , info , and thing about these game you never know . the menu be nice and easy and loading be almost non existent . the best part about this be the save anywhere feature . you save in a spot you load in that spot ... as easy as that . there be no upgrade to the game at all which be a bit of a disappointment since there be many problem with the game . other than that pick this up and you will love it !
