Video games aren't all about pressing buttons – you can control games in all kinds of ways! Nintendo systems include a wide variety of ways to control games, from traditional button controls to motion, touch and even microphone or camera controls!
Nintendo strives to offer a variety of control options so that everybody can play comfortably. For example, as well as the Wii U GamePad, many Wii U titles also support Wii Remote and the Wii U Pro Controller; everybody can use the control scheme that appeals to them the most!
Some games support extra peripherals for more specific actions; for instance, Wii Fit U uses the Wii Balance Board as part of its exercises, and it can also connect to the Fit Meter to track your activity while you're out and about.
