I have 4 controllers so I can do Mario Party, etc when we have friends over. How important would it be for me to have 4 nunchuks? I have 2, but I don't know how many 4 player games there are that require the nunchuks? I just got my wii last week so I'm a bit out of the loop on whether or not I should stick with just the 2 nunchuks, or get 2 more, so there is one for each wiimote.
