My husband used to be very addicted to games, in fact, if he starts again, he will get really into it still. The problem I had with him about the games was that he would get emotionally involved in them and would become really scary when he loses (a REAL bitter loser!!) He's broken many controllers and things around the t.v. because he throws it and breaks it. These days, coming back from Afghansitan and since we are living separately, I have all his games, and he just watches cartoons on the internet when he's bored. But he's taken up working out these days, a hobby I can agree with!! Maybe boys need to release their aggression one way or another.. maybe you girls can suggest the gym to them or join a sports team.
