Unadom Im sorry but I will disagree with you there.
I have NEVER said that gaming was an issue. I saying that excluding yourself from contact with other human beings IN FAVOUR of gaming is an issue. When, as it is the case in the OP, the person spends all their day in front of a screen instead of being out with friends.
The case you are talking about could be ME, as I've actually explained.
Due to ill health I cannot do all these things such as socialising, going out etc...MN is my way to have a little of social contact (or I could spend my whole days in my own sat in my armchair, not moving). But is it as good as meeting people in flesh, having friends you can talk to and share your joys and struggles and whatever you like? Of course it's not! And I'm pretty sure that the guy who joined your group wouldnt say that either.
I found it very interesting of how some people of this thread are reacting very personally to anyone who says 'nope. I don't think that spending youR day in front of a screen is healthy'.
It makes me wonder why.
It also makes me wonder why it is ok to dismiss the experience of someone else when it's not the same that you.
My experience is that MN (and games) is a form of escapism. It's a way to get some social contact when you can't have. It's nowhere near as good than the real thing though and leaves you still feeling isolated anyway. It's not 'real' life with real people.
It's completely different than playing 2 hours with a game and then then having 'a normal life' seeing people, meeting up with friends, going to work and seeing people etc etc.
I know that's how the last 4~5?years have been for me.
