i have to disagree,
while you opinions are interesting there are flaws in the fact you donkt have to use the headset if you dont want to, you would be able to talk to specific people, and if people were swearing just mute them or take headset off.
also its a new way to talk and socialize with people.
i mean a down side to gaming is, its addictive and can lead to bad social lives and very little talking, but with a headset it can increase socilaization.
for starters even idiots know not to give there info out online nevermind to strangers on the games. so its up to them.
i would play brawl without a headsert, but would like it more if there was one
