As one of the earlier three-dimensional platform games, Super Mario 64 is based on open world playability, degrees of freedom through all three axes in space, and relatively large areas which are composed primarily of true 3D polygons as opposed to only two-dimensional sprites. In the game, Mario explores Princess Peach's castle and must rescue her from Bowser. An enhanced remake called Super Mario 64 DS was released for the Nintendo DS in 2004. More than eleven million copies of Super Mario 64 have been sold. It was released in Japan on June 23, 1996, and later in North America, Europe, and Australia. Along with Pilotwings 64, it was one of the launch titles for the console. Super Mario 64 is a 1996 platform video game published by Nintendo and developed by its EAD division, for the Nintendo 64.
