We actually have a growing genre of RPGs aimed at a more diverse and inclusive player base. We could certainly use more. And, of course, they all suffer the same problem any not-D&D games does, visibility under D&D's huge shadow. And D&D itself is becoming more and more inclusive, although it has much further to go . . .Wow. Great question. Huge and sweeping.
What's missing? Just about anything that's not directed at predominantly white, middle-class guys with lots of disposable income and heaps of free time.
Getting into the hobby? Cheaper books, less reliance on expensive on-ramping materials, lighter rules, less math, less homework, more pick-up-and-play, more solo RPGs, and a lot of other things along a similar vein.
Engage more? Mostly the same as above. Less expensive hobby overall with less math and homework, lighter rules, pick-up-and-play, solo play, etc.
Underserved? Anything that's not action-adventure power fantasy set in a fantasy world. Games exist that aren't those, but they're decidedly niche and practically invisible. The audiences that like those other kinds of games are therefore underserved. Sure there's a smattering of sci-fi horror mystery and the odd western, but compared to fantasy they're a tiny fraction of the hobby. To say nothing of every other genre. Romance, cozy, non-violence, community focused, community building, etc. Yes, I'm aware there's like two games that might handle one of those, but that more proves my point than disproves it.
Cheaper books would require different types of books. The standard full-color 8x11 hardcover isn't going to be getting any cheaper . . .
But I've long felt that D&D should ditch the PHB, MM, DMG triple combo as the "core" of the game and release a cheaper, simpler core book that would truly be all you need to enjoy the game. Something between the "starter" rules and the current "core" rules in complexity. I'm hoping for a singular "core" book AND a pick-up-and-play starter box, followed by more all-inclusive boxed adventures . . .
I am seeing more RPG-adjacent pick-up-and-play products in Barnes & Noble . . . which is cool, but aren't quite true RPGs. Still, more of that please!
