4. Donkey Kong
Find me someone who has never heard of Donkey Kong and I'll show you someone who has spent the last twenty years under a rock. This is one of the first games Nintendo ever released and it was the foundation of its empire.
The game introduces us to Mario, who back then was referred to as "Jumpman," as he must rescue his girlfriend Pauline from the clutches of the evil ape, Donkey Kong. The famous Italian plumber (who was actually a carpenter in the original game) must climb his way to the top, making sure to avoid the barrels thrown down by the malicious primate.
