Harken back to my golden age of gaming, a time when the Sega Genesis and SuperNES were head to head in the console wars. There was a game genre that sparked my love of co-op, one that seems to have all but disappeared. From Altered Beast to Golden Axe, Streets of Rage to Double Dragon - the co-op beat em up games were the cream of the crop in co-op experiences. The concept of these games was simple - partner up with a friend and punch, kick and attack everything in your path. They were challenging, fun, and over the top; but once 3D games became popular they all but disappeared.
