It's not that I dislike D&D. It's the gateway drug, if that makes sense--it got me into tabletop, and it's still the system that people default to when you wanna do some pen-and-paper. But I'm also aware that D&D has some weaknesses, like its simulationist ruleset, its emphasis on GM vs. Player, and how little the rulesets encourage storytelling.
If you're GMing, you need to be ready, at any time, to set DCs for anything the players do, adjudicate which check it uses, have statblocks/names/voices ready for any and all NPCs the players can interact with. You create the world, the lore, the adventure, because if you don't have a dungeon full of goblins, gnolls, and beholders, you just end up staring at each other for five hours. What's more, because it is largely the GM vs. the party, players often feel the need to fill traditional party rolls, and any opportunity for non-standard parties or interpersonal conflict gets largely stifled.
Compare that to a system like Apocalypse World or its derivatives Masks, Thirsty Sword Lesbians, and Fellowship. To start with, much of the world is player-generated. Each system primes you with player relations, past deeds, stuff like that, which is all fitting to the archetypes of the players. So right from square one, you're set up with plot hooks and threads to chase down and tase out or forget, as appropriate. Wow, the Brainer stole something from the Hardholder? What was it? Why'd they need it? What are they doing with it? Is it still around? And it's totally legit, as a GM, to turn to a player and say, "Yeah, I don't know the answer to that. But Barbecue, you're the hardholder, whatcha got? You know the troublemakers in New Manhattan, alright. What's the nasty on the people harassing your supply caravans?" Players are invested because it's not just your world; it's a shared world that everyone's contributing towards. And what's more, due to the greatly simplified ruleset, you're basically always set for whatever direction the players go towards! And what's more, interesting characters are not only possible, but encouraged!
Seriously, PBTA games are just a tutorial on how to run fun, interesting games, and I can't recommend them enough.
