An interesting article from Crash in 1988 on computer and videogame addiction.
I know its the kind of extreme examples you hear every time a story like this comes up even these days, i've never heard of prostitution fo fund a "gaming addiction" before.
I also find it interesting that in the little "are you an addict" questionnaire at the bottom 15 and 25 hours a week are considered addiction.
Most office workers will get paid to use a computer for around 40 hours a week, and i'd surely use atleast another 15 hours in my own time.
