Yeah, I've been playing various editions of D&D (Pathfinder now) for the last 33 years. And lucky for me, my current gaming group has been the same one since 1987 - lost one member through an accident, but gained 4 more in the last 3 years. Of course since my evening job is developing settings and adventures for Pathfinder, I get to play all week long - sort of...

3 of us switch the GM role every couple of months, so we don't get burned out.

There are plenty of members who are fantasy authors, GIS pros and others who aren't gamers at all. Though I'd hazard to guess most members are RPG gamers.
