X is a problem with the community or structure of a game such that others can have a large negative effect on your gaming session. Usual recommendations: solo, bring your own friends/group, avoid potentially risky (i.e. anything involving gameplay) interactions with others.
I keep saying that if game Y is fun so long as you bring your own group of people, almost anything is fun if you are just using it as an excuse to hang out with your friends, so the game is contributing nothing. You could randomly pick any of dozens of options, and you will probably be better served by playing something other than an MMO. But most folks seem comfortable with this equilibrium in which we are contact with building gated communities within gated communities instead of pushing for pro-social game designs. This pushes me away from MMOs, because what’s the point without that first M, and into lobby-based games where we get up to 4 friends together, done.
On one hand, this is a natural consequence of the Hell that is other people. On the other, shouldn’t we expect better?
