Recently DS6 stumbled across DH's Dungeons and Dragons books. He's fascinated. It's the first fantasy anything he's read or taken an interest in. So I would like to encourage it. Since it's a face to face adventure, it'd be great for social stuff too (even if it is extremely geeky). That being said, I don't think D&D is played by anyone under 40. Please correct me if I'm wrong. Is there an equivalent in today's time that we can pursue?
Note: This type of stuff has never been my 'thing'. So I'm looking for guidance here. I am not crazy at all about online games played with others.
