are you implying that WoW users had sex because they couldn't play WoW? I think you are mistaken. I would predict more of them killed themselves
A lot of WoW haters in here. It's just a game people choose to play, albeit a very time consuming game. That doesn't mean everyone who plays is depressed or any worse off than people that don't play are. It's no different than any other hobby/activity that is time consuming (like sitting in front of the TV for hours watching sports or movies).
The comments from players stating "I used to play, but then I got a life", that is just sad. You are basically saying you suck at balancing your priorities. If you are that upset with how much you play the game, just do something else and come back later, the game isn't going anywhere. If you can't, then you probably have an addictive personality, and in that case be thankful that wow is your only vice, there are much worse things to be addicted to.
