Thanks for saying this. I have to say, this idea that D&D was common language back in the 80's certainly wasn't my experience. Outside of my geeky friends, no one had the slightest idea what a role playing game was, let alone what Dungeons and Dragons meant.Ignoring the unpleasantry...do you have data to back that up? I feel safe assuming that for tons of people who went to high school in the 1980's, D&D never came up at all, and for plenty of Gen Zers D&D comes up all the time at school (as noted above, more Middle Schoolers currently play the game than Baby Boomers or Gen Xers combined).
Good grief, I left my DMG out on my desk at my work the other day, and my student, a 45 year old Japanese dude, knew exactly what it was. THAT'S how much market penetration we're talking about now.
