As I was playing on my Wii awhile back I was wondering if there was really a need to make the Nunchuk thing as a separate component, because couldn't Nintendo have just added an analog stick and another two buttons onto the Wii-mote and accomplished the exact same thing?
I think it would be possible to swing a remote and move an analog stick on that independently, just so long as it was positioned in a convenient spot. The only thing you would miss out on with this is the limited motion input that the Nunchuk provides, but the way I see it for something like a boxing game or whatever else you'd need two things, you should have just been able to link two Wiimoted together, and that would also be great for a drumming game or something too.
