The classic game that created the plumber who would rule the gaming industry is up next, and it holds up decently. In it, you play as Mario (his debut appearance), and climb scaffolding in order to rescue Pauline from the titular character, Donkey Kong. This game is simple fun, but there is one slight problem: the game only really has three stages. After clearing all three, you simply go back to a harder version of the first. Regardless, give this game a try, if only to see where it all began.
