So you’re saying they had zero correlation? No one was drawn to D&D by virtue of Critical Role or Stranger Things. It was entirely internal organic growth?
A lot of people claim that D&D's success is because of Stranger Things and Critical Role. There are a lot of contributing factors of course, but there was no significant increase in sales of D&D after the release of either because it was already on a significant upward trend. It always feels dismissive of the fact that a lot of people just happen to have fun playing the game, it simply works for many. Which is no reflection on other games, I just don't see many other games like [spin the wheel of RPGs to get a random game] Call of Cthulhu having such broad appeal.
