Well, D&D is quite different from music. Or food. Or videogames.
Sure. It is different. But then again, food is different from music. Art is different from videogames.
I don't think there's a single one hip-hop enthusiast out there who never ever heard anything but hip-hop. You just can't simultaneously be enthusiastic about a genre of music and never be exposed to other genres. People who like hip-hop like like hip-hop because they truly like hip-hop. In order to like hip-hop, you need to have a taste in music — you really need to know what you actually like and what you don't.
See, I don't agree here. You just assume others are worldly. But as the old joke goes, "I like both types of music, country AND western."
There are tons of people out there that just like small slices of things. They don't need to experience all the music in the world to know what they like. They don't need no fancy cuisine or NEW YORK CITY salsa to like the food they eat.
The giveaway is what you wrote- "you need to have a
taste in music" Sure, if you want to erect barriers and assume that some people are better than others, and everyone would like the same things if they just had the same impeccable taste ... why not?
...that never ends well.
Many people I've talked to (or just observed talking to other people), both IRL and on the Internet don't really want D&D specifically, they just want a roleplaying game. When someone tells you a story how they played a 5E campaign without a single combat and how much fun they had investigating a murder mystery or being spooked in a haunted house or just talking in-character or whatever as opposed to boringly slaying goblins, question "then what was the point of using D&D 5E ruleset?" immediately pops to my mind.
So many people conjure these "many people." I mean, okay? Like ... sure. Why not. In today's day and age when you can't even scroll around on Roll20 without seeing other TTRPGs listed, no one even knows about other games? Or sees them in Amazon or the local store when they buy their D&D books?
Again, it's weird. It's the feeling that people just don't know better, and if they did, they would choose differently. It's possible, for some people. There are people that play D&D and migrate to other games. But there's also a lot of people (the proverbial "many people") that do try other games, and end up back playing D&D, right?
I truly don't understand this reasoning. Let me correct that- I do understand it. I do understand why people might say, "If it wasn't for those meddling kids and the stupidity of the average gamer, {insert favorite game here} would be more popular, not D&D! It's BETTER!"
I understand that, but I fail to understand why people aren't more curious as to the success of D&D. At a certain point, who are the fools - the people who keep claiming it's a stupid game for stupid people who don't know better, or the people making the money?
In other words, if a company is making a game with the goal of being broadly popular, and constantly iterates on that, and constantly surveys the user base on that, then maybe there is something to it? Perhaps asking people what they want, and giving it to them, might account for some measure of the popularity?
