About the video, I believe that WOW is one of the most addictive worst games out there, and I am sorry to say this but I always get away of it and kept it really far away from me, I got a friend that DIVORCED because of WOW, he kept playing in the night, arriving late to the job, never pay attention to her, starting to got problems of agoraphobia and finally she divorced, for a good reason I need to say even if he is my friend.
Addiction doesn´t just show off as an unstoppable willing to play. In the last days some criticized this guy for being a violent asshole (and he is of course) but I believe has much more to be with the fact HE IS VERY ADDICTED , junkies have similar violent reactions out of drugs, without the need to be "patriarchal" or "gender violence", I bet this guy were hit his brother, or mother for just interrupt him playing because he is fucking addicted and SICK.
(She seems also to throw things at him, to the point of breaking his patience, but he crossed the line, so both may been having problems, but he crossed the line for two things, 1st) if she is throwing stuff to you, you stop playing and you say "hey whats wrong" in a good way, and stop her bad behavior in a KIND way forgetting the fucking game, 2nd) he does the same as her but much WORSE and strong, not consider she is pregnant, this is just out of the line by far)
All these seems to point to a big addiction IMHO
