Super Mario Bros (NES)
It all began on a September day in 1985. A little man in a pair of red overalls was about to change the world and become a pop-culture icon. But no one knew it at the time. As you would run, jump, and squash your way through the eight worlds of this game, you were treated to the reward of finding out that the princess you were looking for had already been moved to another castle. But never before had gamers experienced such frenzied gameplay. The little red plumber became a nearly overnight success, and he has been riding that wave ever since.
