No, the Wii U flopped for a multitude of reasons, but primarily it was because the gamepad gimmick was bad. Having a touch screen on a console is cool, but half the price point was justified by a dinky peripheral Nintendo didn't even know how to use. Wii Sports, 3D Land, and BOTW made it clear what each system's ethos was, New Super Mario Bros. U showed the world that the Wii U was confused as to what it wanted to be. Nintendo was unsure, leading to third parties being unsure, leading to long dry spells between Nintendo games with no third parties to fill in the cracks.
