I was bringing up what I think is a serious point which so far I haven't seen anyone else really touch on. People are going to fight over that one controller, especially kids who don't like to share with their siblings... bad stuff WILL happen because of this. If parents could buy additional tablets so every kid could have their own everything would be peachy, but that's not going to be possible on this console. The topic of buying replacement controllers has been discussed, and if you figure people are going to be fighting over it the likelihood of it getting broken and needing to be replaced goes up exponentially. Nintendo may even face lawsuits from people getting hurt fighting for control over it.
Other players can use the wiimote, but realistically, how many players are going to be content with that while someone else is hogging the cool uber control?
