I'm that kid who wanted to play D&D growing up but NEVER could find a group. When a fellow dad (we're all in our 30s and 40s now) asked me if I'd be interested, I jumped at the chance!
I run a weekly D&D game for a group of 30- and 40-somethings, when I'm travelling, we move the game onto Roll20!
I also run a game for the kids of most of my players (ages 6-10). We started with the Hesiod games by Susan J. Morris and WOTC, and continued the story from there!
