I think it would suck compared to a traditional game controller, if it were to be used as a traditional game controller. As say, a motion device, it could probably work just as well as any other controller. But there are of course ways to improve the experience. For example, you could show the visual feedback on the TV itself, so you can see where you are touching relative to the display. Similar to how the Kinect shows where it thinks your hands are.
