Tell you what, Razor, you have kids, let them hit puberty, then talk.
One of the biggest things you learn as a parent is that, after a certain age, it's about the choices your kid makes. Father says put away the XBox, kid says no, shit goes downhill from there. Who fucked up, the kid for disobeying the father or the father for saying "My house, my rules, follow them or you're welcome to leave." Some kids develop an unhealthy attachment to those disgusting video games to the point they let everything go to hell in a handcart, they have no social life, they stay up all night long playing them and school drops into the toilet. What the hell is a parent to do? Go "that's nice son, you go kill those bad guys, I guess a D- in English Lit. is the price we pay."
As a parent, when your under aged kid threatens to run away, you expect their asses to head to a friend's house, lay low for a few hours, then come skulking home with their tail between their legs around 10:00 p.m. and apologize and accept their punishment, not call some fucking stranger they hooked up with on the internet.
And as a parent you have the responsibility to enforce the rules of your home. While what happened is awful, I still can't fault the father, I'm just sorry he waited so long to enforce house rules and the results were so disastrous.
IMHO, video games are foul, nasty things and should not be in a household with children, period. Like cigarettes, they should have a warning label and nobody under 18 should be able to play/buy them.
