My girlfriend and I actually met playing CoH over 8 months ago. We were apart of the same supergroup and still are. I helped her achieve her first level 50 character by staying up with her until 5am in the morning (eastern time) for a week straight and we just grew to like one another. We talked for months on end and after a long wait we finally got to meet each other (we used to live 800 miles apart) and it was all love from there.
Funny thing is, we're not the only one to meet through our supergroup. Our SG/VG has five couples in which four of those actually met through the SG. My girlfriend and I are the latest addition to that number.
