I prefer to play D&D with players who are in roughly the same demographic as me: 30-something, married, professionals.
I am in my late 30's, married, and have been playing D&D since I was a kid. I enjoy both playing and DMing. I have a game that I'm playing in currently, but I would like to run a game if I can find a couple more players that I click with. That is the crux for me because I am picky about who I want to spend such large amounts of time with.
