This may sound stupid, but I'll ask anyway. We just got Wii for our kids for Christmas, and were wondering what accessories would be considered "mandatory". We got WiiPlay with it, so we have 2 remotes and the one Nunchuck that came with the console. We also got a charging stand for the remotes and an HD cable. Anything else we should get for Christmas day gaming? How many remotes and nunchucks should we get (we have 3 boys plus us= 5 potential gamers)?
