the fact that you keep insisting that every baseball fan in the world would watch the World Series continues to baffle me.There were an average of over 30 million who watched each game of the world series. The maximum any game had of those who watched were 50 million.
An average of 15-16 million watched each game in the US.
In context, if there were 80 million D&D fans in relation to those numbers, it would mean if you walked down the street in any US city and asked each person you would have a 5x better chance of talking to someone who was a fan of D&D (Fan, not just someone who knows it exists) than you would of someone who watched the Baseball World series.
I'm a fan of the Seattle Mariners. Why would I watch the World Series?
As a fan of the Seattle Sounders I'm a soccer fan, but that doesn't mean I'm a fan of a random game in England.
A fan doesn't interact with 100% of each subset of the fandom. That's never how marketing and fandom work.
Baseball has about 500 million fans, which includes people who go to a college game in Japan or a national team game in Cuba.
D&D having 80 million fans doesn't mean that it has 80 million players, because fandom has never meant that.
