Fun. Pure and simple. Thats what I think of when I think Super Mario Bros. Looking at this video, its clear that the designers at Nintendo understand fun on an extremely deep level. Take a look at everything in the video, from the the expressions on the enemies "faces" to the color palette to the camera work to Yoshi shooting his tongue out to latch on like a Bionic Commando extension. The variety of stages presented is nothing short of astonishing. When it comes to 3D platforming games, Nintendo has no peer. But beyond the constant innovation and the constant purity of the gameplay in their Super Mario Bros series, its somehow still incredibly fun 25 years later, and thats what makes Nintendo different from other developers.
