Nintendo Wii
I understand that Nintendo wants their system to be as family friendly as possible, but from what I have read a lot of people are disappointed with Wii speak because you basically have to yell at it so that people can hear you and Nintendo says that they never plan on using any kind of headset because it promotes people using bad language and things like that.
I believe that it is up to the parents whether or not their kid can use a headset, if they are not responsible enough just don’t buy one for them!
