after I played it about 20 times I got bored soon because there’s no Sonic the hedgehog 3, streets of rage 3 or michael jackson’s moonwalker, oou and rystar but rather a lot of adventure and sword games and those aren’t really my style but official sega product with 51 games and option to add 1000 more so nonetheless it’s a must buy! unit comes with one box,a manual, one sega genesis mini, one 3 button genesis controller and for an extra 15$ one wireless 6ix button controller in case and box
