Of course any kind of addiction it's bad, my grandma used to say something I still use and think for somethings "everything in too much quantity is harmful" (kinda like that, idk how to translate). Since child my parents PROHIBITED videogames in the weekdays. (except in holidays and vacations, sure, AFTER doing any kind of homework and schoolworks), this until half of high school, where me and my brothers got used to it, and we took it as a 'everyday's duty'. Throughout the time I could realise how different would be if I were allowed to play whenever I wanted, this made me search things to do, playing at home with toys and mainly to go outside and play anything with friends, a lot of sports by the way, and constructing a network and real social relations. This helped me a lot, I'm sure it would be a very different me, because I know that I wouldn't go outside, I always loved and would be playing instead of much things. I just don't know if it was the best way to do, because at weekends, sometimes, I used and wanted play more than anything in this world, sometimes not going outside to play with friends or doing homeworks as fast as possible to play. Maybe quite a few hours to play (1-2hr) per day would work, but I don't care about it, maybe when I have a child, which I'll CERTAINLY do something like that, to moderate. And incredibly I still do (most of the times) and think like that, just something I wanted to adopt in my life, giving priority to real life, an activity preferably on weekends, when I have no obligations anymore. Just a way to think and a way to moderate the thing, in this case, videogames. But never prohibiting, this and almost anything, videogames are an awesome tool to learn, meet people and so much, we just have to moderate in my point of view, and anyways, it's very nice to see diferent opinions and talk about it, which may be an addction, thing most we know how bad is.
