It's really not as bad as we might think.

For gaming disorder to be diagnosed, the behaviour pattern must be of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning and would normally have been evident for at least 12 months.
Studies suggest that gaming disorder affects only a small proportion of people who engage in digital- or video-gaming activities. However, people who partake in gaming should be alert to the amount of time they spend on gaming activities, particularly when it is to the exclusion of other daily activities, as well as to any changes in their physical or psychological health and social functioning that could be attributed to their pattern of gaming behaviour.
I mean... there ARE people who binge MMORPGs to literal death, and there really should be an awareness of that. :|
I was in 12th grade back when Final Fantasy VII came out and... well, I pride myself with not having totally killed my grades, but... it wasn't easy. No sireee. ;) But even that serious binging wouldn't have been evident for
12 months straight.
