Everyone needs to realize that just because redsteel sucked doesn't mean every game has to do it the same way. Expect to see innovation that will make this work. The on rails shooter inside Ravings Rabbits is great. Will be interesting to see if someone can figure out a good system for a FPS.
One example. Move with nunchuck look horizontally by pointing Remote left and right, BUT not neccesarily at screen so you can hold it at an low angle. Have up and down looking fixed except when your pressing a certain button. Something along those lines could work, but we will have to see.
