Some like me find it very distracting to talk to someone while playing videogames, I absolutely never talk while playing single player games and during multiplayer I talk only to the players in my team. Playing games is not work, it is for fun and talking while playing for me is like talking in a theatre.
In other words, no. It is useful though, if you want to talk to someone playing other game while you are not doing anything. But not much of a big loss.
