Here in NYC it feels like game nights/board game afternoons are the golf of the programming class. It's kind of assumed that you can play socially, there are gaming circles that also end up serving as industry networking. And you can invite a coworker to a game night and they'll understand that it's social, and not a date, and it's ok if they play really badly as long as they show good sportsmanship.
Is it like this in other cities too?
Edited to add: By the way, I am someone who loves a few board/card games and doesn't love most of them and is willing to play many of them if that's what everyone else in a group of visitors wants to do, and I believe I recognize many of their virtues and their downsides. What I'm specifically curious about is what other cities have this same kind of scene.
