I don't think that people that got fat because of playing games to much will play games using a wiimote. I don't see any way to be competitive using a wiimote whilst playing gunz. computers are not often positioned at ideal places for playing using a wiimote. It would probably be fun to try but that's about it. if you wanted it to be any fun there should be a special server/roomtag for wiimote only play, otherwise you just won't be competitive. it also seems like quite an ambitious job. goodluck
