The point of the Wii U is that it has a fancy, touch-screen controller. That may not be suitable for all titles, though. Especially ones being ported from other consoles.

That’s a thing of the past, as both the Wii U Gamepad and this Pro Controller both have a circular housing, which should allow for a more precise range of movement.
