While I agree with there being a gaming addiction and the downsides of such illness... I wouldn't consider 7 hours a week of gaming as a gaming addiction. That's an hour a day, which is totally acceptable.

There are those who literally live and breathe gaming, don't sleep, don't eat, don't socialise, can barely go to the toilet properly in their lust to get back to the game, and many have died or have had their children die because of their obsession... but, that's a fair chunk longer than a mere 7 hours per week.

I probably average about 24 hours a week myself. :D But I still manage to cook, clean, be creative, study, look after my family and home, go out and about, have friends, experience life...
