your friend sounds like he needs some help. And I don't mean with unlocking all multiplayer class achievements!!
I'm on it, mate. I absolutely believe that this sort of addiction exists and I was close at one point myself (Delta force : Black Hawk Down multiplayer on the PC, believe it or not).
You'll understand it's a tricky one for me to tackle for two reasons. Firstly, I live with him so don't want to cause an argument and secondly, I like a game myself so will often jump on with him for a few maps.
Last night when I was at work I posted a link on his Facebook wall to a gaming addiction website. From his point of view I was obviously just taking the piss but as you know, I was semi-serious. Me and a friend then started quoting 'signs' of addiction at him. He argued back (we were amazed that he stopped playingfor long enough to reply, though probably between maps).
By the time I got home, he had stopped playing and was surfing the net. We even had a conversation about random sh*t for about an hour!
Small steps but the seed has been planted in his head, maybe that was all that was needed. Time will tell.
