The arcade game Donkey Kong was released in 1981 and the world has not been the same since. Three of the most iconic video game characters ever star in this timeless classic. Donkey Kong (no kidding), Mario, and Princess. The goal is simple. Mario must save Princess Peach from the vile clutches of that no good ape. Donkey Kong will try to hit Mario with barrels (among other things) to keep him away. An old game that is still fun to play today.
