It is worth noting that House of the Drafon is more niche than D&D: the Seaspn 2 premiere had 7.8 million viewers, which is quite nice (NCIS averages 12.9 million viewers per episode), it more people than that play D&D: I would posit the Venm diagram overlap between HotD viewers and people already playing D&D is rather high.This.
Vampire hit a niche market. It sold probably 1/10000 of D&D. D&D is a general audience game, built for friends and families of almost all ages. And, like I said earlier, House of Dragons is a Hollywood production. Those, for whatever reason, seem to remain outside of the TTRPG social norms.
