The worse thing, when you think about it, is that socialization business in Ultima Online and others used to happen at the time when most of us were stuck with RTC modems, slow transmission, and payed by the hour. That means the awful lot of time you spent socializing in games and forums was time spent not doing anything "useful".
And people did it, nonetheless. They loved it. I remember when I was on a RTC and downloading some warez bullshit through Kazaa. The 3 KB/S strain on my connection made me unable to do anything else, so I used to go to IRC and chat about random shit all day long. There were small communities, and I considered the people present in those channels as much as friends as anybody IRL.
Now, IRC is dead. "What's the point of chatting on the Internet with people you don't already know" seems pretty much the usage of the Internet. In the year 2000, I remember in the halls of my faculty someone mocking the Internet, saying things along the line : "Yeah, on the INternet, they say you can talk to people all over the world and that it's great... is that what anyone really does, though ? Who the hell does that ?". I shut my mouth, because, I did. I was witnessing the future of the Internet, and I didn't know it.
The problem OP pointed in games is not a game problem. It's indeed a society change. The entitled, the fragile, the weak, the people who need the instant gratification proposed by F2P games whose mechanics have pervaded into even so called hardcore games are to blame. Everything has to be easy, and accessible. And by accessible, it also means you have to be able to have the time to do it. As you grew up, you not only needed time for your work and family, but to Facebook, to Twitter, to Snapchat, to read the latest bullshit on Gawker, see the movie everyone was talking about, read the new 50 shades, play the latest Free To Play, play the latest hardcore game, etc.
As a wiseman once said :
And indeed, I find that focusing helps things. Society and the Economy are lying to you when they say you can do all the things they have to offer. There is a limit even the richest of man can't go above : available time, and the human brain. Less is more. Buy a game, play it fully until you master it. It's the only way to enjoy it. Take your time. Just because 35 "Must play 10/10 !!!!" games got released this week doesn't mean you have to play them. Limit your website consumption : I find out that the only thing I actually ever use, besides convenience stuff like email/bank/amazon is Wikipedia, two news websites, Codex, Google Newstands to read my subscriptions to magazines (stuff I could be doing offline, really)...
I have no idea, however, on how to save socialization mechanics in games because, really, there's no helping other people. It's gone.
