The controller, called Gamepad, has a built-in touch screen. And the system can wireless to both the Gamepad and the television at the same time. So you can play games in which the player has to change between the two screens. Or multiplayer games in which some players look at the TV while others look at the controller. Or you can just play games on the controller and forget about the TV which we were surprised to find might be the most interesting way to play on my favourite system .
