Age 13 - mid 60's. The oldest in our group is a grandmother how loves playing D&D & Amber with her sons and grandson's. Our Median age is 30 something.
My group is 16 (or is it 17?) to 36, with me (at 18_ DMing, though the 36 y.o. has been playing longer than I've been alive I was kinda intimidated when I frist decided to DM a game with him as a player, but thus far, it's been lots of fun, and everyone has brought something to the table
Voted yes. Two of our group are rearing their young'uns in the traditional fashion, so we have two gamers at 11 and 13 on the young side, and others in their early forties on the other side, with a few thirty-somethings thrown in for good measure.
