My husband and I play. He'd heard about an escalation tournament at a new wargaming shop that had opened so him and a few friends decided they would give it a try. Initially I wasn't very impressed, I thought it was the hobby of teenage boys, but a bit of research showed otherwise so I joined in too.
That was Warhammer. We're now getting into Warmachine and, of course, Malifaux.
Our good friends live across the road from us and they also play, so that's another couple. I don't think I know any others though.
