Fine. We'll do this. Again.
Bah. Trying to counter nostalgia(?) with "numbers" and "facts".
I don't see how the 80s D&D craze can compete. The exposure and age range, not to mention international sales makes a huge difference. Way back when, the oldest players were by and large college age. Now that generation has grown up and are playing with their kids along with a whole new generation that grew up with fantasy games inspired by D&D as well movies like LOTR and Harry Potter.
Fantasy (and super hero) movies are more popular than ever. There's a backlash against all gaming being online. I would say that openly acknowledging that you're a geek is more popular now than it ever was. Add in accessibility and awareness from podcasts/web series like Critical Role and dramatically larger numbers don't surprise me at all.
