But dude, Diablo 3 is not Heroin and to say that it's beyond him to try and develop some better habits and self control is just weak, childish, and too melodramatic to be taken seriously.
Um...not playing is self control for him. What the hell do you care if some dude plays a game or not? For him, Diablo might as well be heroin, because that's how his mind responds to Diablo. He has developed a better habit: not playing at all.
