How many hours do you spend on gaming ?

Too many to consider it healthy (over 16 per day). I try not to think about it.

I probably do about 4 hours a week. I'm up to about ~300 hours now on Witcher 3 and I've been working on it for a year at least.

During the week i play about 4-6 depends but on weekends i spend anywhere up to 10-12hours online.

mostly weekends i spent 10 hours not on just gaming

i have generated roughly 3500 hours playing dota 2 it has been fun all i see is those hours going higher and higher

Unfortunately, much more than I would like lol. But it has decreased in the last years are only 2-3 hours a day of formerly 12 hours. I'm a little afraid I'll play more with WoW Classic again.

About 2 hours max, a lot more time is spent developing games.

Way too many than I should have lol but I do work now which is good so not too much time before I'd spend every day 12 hours straight just gaming probably

Depends on the day. If im feeling antisocial i can spend around 18 hours playing but sometimes work and beautiful days get in the way of that.

I don't get to play as many hours as I would like, but on weekends which is when I do get some play time I generally play 4 or 5 hours before my eyes start to get tired.

I do suffer from Dry Eyes after Lasik surgery (not sure if that has an impact or not) so don't assume my figures as a general point of reference.

When I did play a lot more back when I was doing world of warcraft daily I used to play roughly 10 hours a day (I know, at times it was like a full time job).
