Yeah, we did actually, COD Blops2 and Ghosts both had stellar wiimote controls, In fact for as bad a game as it is, Ghosts has the single most flawless use of Wiimote aiming the controller ever offered.
The real reason we saw no wiimote shooters other than these is because almost no one supports a peripheral that isn't the de-facto standard interface for, or bundled with, a console.
Also I couldn't disagree with you less, after my own very extensive testing, yes, they are objectively superior to dual analog, a limited, dated legacy control scheme that is pretty much the most non-immersive, resrictive and limited method of playing a shooter. The Wiimote was immediate, and as precise as your coordination let you be when programmed right, it was the closest you could get on a console to a proper, mouse-like experience. Dual analog is lazy and games that use it almost always contain aim assist features specifically to make up for the lack of real precise control.
