Nintendo's best games very often don't feature incredible storytelling or realistic graphics; the company has made its name through the gameplay itself. Many of its best games feature mechanics that allow for player interpretation, as seen in the ways players utilize the movement mechanics of games like Mario 64, Sunshine, and Odyssey to perform acrobatic feats that make the intended route appear like a mile-long walk.
