Donkey Kong

Donkey Kong is not only Nintendo's first real smash hit for the company, but marks the introduction for two of their most popular mascots: Mario (originally "Jumpman") and Donkey Kong.

The game is a platform-action game that has Mario scale four different industrial themed levels (construction zone, cement factory, an elevator-themed level, and removing rivets from girders) in an attempt to save the damsel in distress, Pauline, from the big ape before the timer runs out.
