I think that same game developers should look at SSBB and realize that not EVERY game needs to use the Wiimote.
I know it's the main feature of the console and all, but there are some games that would be better off using the classic controller or even the old gamecube controller (which I really think was one of the best designed controllers, ever).
The new Mortal Kombat game for example, I don't see how they would use the Wiimote for it and still make it enjoyable. I guess most of the examples I could think of would be fighting games. But I'm sure that there are others.
