The Wii U was the first Nintendo console to support HD graphics. The system’s primary controller is the Wii U Game Pad, which features an embedded touch screen, directional buttons, analogue sticks, and action buttons. The screen can be used either as a supplement to the main display or in supported games to play the game directly on the Game Pad. The Wii U Pro Controller can be used in its place as a more traditional alternative. The Wii U is backward compatible with all Wii software and accessories.
