The things I've done to get him off computer games over the years are unbelievable really lol. There's not many who'd put up with what I have with gaming addiction, I wanted to send him to the WoW rehab centre at one point lol.
I've hidden power cables, flicked the trip, kicked consoles (nintendo's don't break), and folded a disc in half before. When he's at his worst it drives me to distraction. He's getting better but it still annoys me when he insists on talking on skype/ps3 headset, I don't mind the gaming so much these days as long as it's not online, I don't see why his mates should be in my living room of an evening and if he's online gaming he obviously can't help with the kids.
But in his defense he is better than he was before the children came along and doesn't usually play in the day.
