This isn't meant to be hateful, I'm genuinely curious. There are so many new Tabletop RPGs out there that it's crazy to me people still play D&D after 45 years. It's certainly much more popular than a lot of the other RPGs that came out around the same time period. What is it about D&D that makes it stand out above the rest?
This isn't meant to be hateful, but . . . .
Gotta love an opener like that!
There have been "
so many new TTRPGs out there" since the 70s. D&D was the first, but it didn't take long for a plethora of other games to debut. We certainly are in a golden age of gaming with the popularity, playerbase, and number of different quality RPGs out there right now.
D&D managed to tap something primal, it was the first, and in many folks experience, remains the best game out there. It's the category originator that, despite ups and downs, remains well supported by it's publisher and the fan community.
Why DON'T I play games other than D&D (that often)? I'm primarily a fantasy fan, and I haven't run across a game yet that does it better than D&D. There are a lot of good fantasy RPGs out there, and I love checking them out to steal ideas from (rules widgets and world-building). I'm willing to play other games if somebody else wants to run them and invite me (and I have the time), but most folks starting new games are playing D&D. When I decide to run a game, D&D is my jam, but I also know that I'll have better luck recruiting players than for just about any other game.
There's also investment . . . I have a lot of D&D material I haven't used yet! The other RPGs that tempt me, are often just as book-heavy and expensive, and I'm not ready to make that new investment. The more "light" games with only one or two books, tend not to interest me.
Ultimately, why do you care?
I've got no issue with gamers who prefer NOT to play D&D, and have some other game they obsess over. I've got no issue with folks who play a variety of RPGs at their table. If you and your gaming group are having fun, you're doing it right! But I DO get irritated with folks who question why D&D remains the fan favorite with the implication that it doesn't deserve to be my favorite game. Your question reads, perhaps unintentionally, "Why play D&D when there are so many BETTER games out there."
No, there are not any BETTER games out there than D&D. There are a lot of very good games other than D&D out there, games that some folks love way more than they love D&D, and all that is cool. Which games is the best is completely subjective. You play what you like, and I'll keep playing D&D.
