That's true. I only own 3 controllers and two nunchuks though, and the third controller is because of Wii Play. We have friends (another couple) who also have a Wii, they bring controllers/nunchuks over so we can do 4-player. Wii Sports Tennis is simply amazing with four players, and very funny to watch when the players are drunk. No serious injuries so far either. We'll actually be bringing our controllers and games to their place tomorrow night.
