Your links are very broken.
They are, in fact, so broken that when I fixed the one I went to in my address bar, it was still broken, and I had to fix it a second time.
Just thought you ought to know.

That aside, I'm looking forward to listening to these.

Not sure if this goes here or in the "Apocalypse World" section. I guess I'm putting it here.
I'm not making a full-fledged hack. Rather, on the bus to Game Night today, it struck me that we could throw together some rules for playing a colonial America revolutionaries-themed game in honor of the 4th of July, and that the simplest way to do it would be to start with AW and go from there.

So it's got mostly the same stats, the same MC moves and principles (aside from the obvious exceptions), most of the same basic moves, and none of the gear or peripheral stuff save harm.
Instead of playbooks, I said "Pick stats that add up to +3, and make up two custom moves apiece, and that's your character." For Hx, I asked them a couple of questions: "Who saved someone else's life? Who owes someone else a debt?" Then once all three players had some kind of relationship, I told them to identify who (if anyone) in each relationship had power over the other one. Then I said to put down +1 for anyone who had power over them, -1 for anyone they had power over, and 0 if it was even.

So we got a nice little triangle: The general saved the native woman's life, the salt baron is negotiating with the native's tribes over land use, and the salt baron used money and political power to get the general his rank. (As an aside, it's not actually America, it's an alternate setting... where the America-analogue continent rose from the sea a hundred years ago, and is populated by indigenous frog-people. No relevance, I just wanted to say it somewhere.)

I also replaced two basic moves. Seduce or manipulate is now:

When you make an impassioned plea or heartfelt speech to an audience with some shred of sympathy, roll +hot. For NPCs: On a 10+, they believe you without reservation. On a 7-9, the MC chooses 1:
-They go along for now, but with doubts and reservations.
-In the long run, you've swayed them, but they'll carry out their immediate intentions anyway.
-They'll listen, but only if you offer something tangible
-Some of them believe you and are swayed, but some of them don't.
For PCs: On a 10+, both. On a 7-9, choose 1:
-If they act in accordance with your desires, they take +1 forward.
-If they contradict your plans, or act against them, they take -2 forward.

(For NPCs, the first two options, I'm dividing what might happen up into two things: Do they do what you want now, and do they change their beliefs in the long run. On a 7-9, the player might get one or the other, but not both. For PCs... I guess this essentially lets them help or interfere with hot instead of Hx under some situations. Do I want that? All of a sudden, I'm not sure.)

And instead of opening their brains, they get to do this:

When you take a moment to consider an environment familiar to you, tell us about some feature or attribute of the landscape and roll +attuned [replaces weird]. On a 10+, it's as you say. On a 7-9, you're mostly right, but the MC will add or change some significant detail.

(Sharp might have made more sense. I guess I was going for some sort of possibly-not-entirely-PC Native American knowing the lay of the land in a slightly mystic way sort of thing. Except I also envision for instance farmers being attuned to their farms, or urchins being attuned to their cities and knowing where all the hidey-holes are. Also still not sure about does it have to be a place that they've actually been, or can they do it in, say, a forest, if forests in general are familiar to them, never mind that this particular forest isn't anywhere they've been before. Maybe not a big issue in practice.)

And for the characters' moves:
The native frog-woman has one move that lets her roll +attuned to summon an army of ghosts on a 10+ and a vague, creepy fog on a 7-9. She also has a move that lets her take strange drugs to have visions, where on a 10+ I guess it's like she opened her brain, and on a 7-9 I still tell her something but she takes -1 ongoing for the rest of the day. On a miss, -1 ongoing and she gets weird hallucinations instead of useful visions.

The general can roll +attuned to let the spirit of War possess him, which gives him 3 hold (10+) or 1 hold (7-9) to get +1s on rolls during battle. He also straight-up took the hardholder's Leadership move for leading his army.

The salt baron can roll +sharp to buy things he needs, which have flaws or strings attached on a 7-9. (We're not using the barter rules.) He can also roll +hot to find useful people, but on 7-9 he owes them a debt.

So that's what I've got so far. Any feedback or suggestions would be most welcome. We'll probably play our first real session next weekend, so I have some time to decide what else we need or don't need and make changes accordingly. (Any media I should consume? What happens in stories about revolutionary America, anyway? Not usually my genre. Nor am I much of a history buff.)

My strong suggestion: Don't worry about hacking the rules to make them run faster. The game already runs fairly snappy as-is. Don't worry about getting the players all together or explaining their absences, either - the game already assumes they aren't always in a group and works fine under that assumption. Else, what use is the Savvyhead's bonefeel move?

Instead, worry about bodies at the table. 12 players in the same campaign, I dunno, maybe you can make it work if you rotate them out or something, though it'll be messy at best. 12 players at the same table, my direct experience says won't work at all. Not one little bit. 8 players at the same table won't work. 6, just maybe. I personally wouldn't go any higher than 5, and prefer 3 or 4.
I suggest you don't break those numbers unless you want sessions where at least one or two players have to sit there the whole time without getting a chance to do anything at all - which was a regular feature of the 8-player game I ran. Even when we were missing a player or two. Too many players at once, and the whole game becomes a confusing mess where nobody really has enough screen time to accomplish much at all, certainly not to make something of their world. Plus, you, the MC, can barely get an NPC in edgewise.
That's what happened when I did it, at least.

Me, I'd either split into two groups of ~6 and get one of your friends to be the other group's MC, or else just pick 5 or fewer of them and play with the smaller group alone.

(Not convinced? Imagine twelve people in a room, all trying to have a meaningful conversation together, and you tell me how that goes: Awkward at best, right? Or about half the people are barely saying anything? In my experience, conversations with 12 people tend to naturally splinter into conversations between 3-6 people anyway, you know what I mean?)

+Sharp because I see this as being more about the Angel using a steady hand and a keen eye to carefully remove the sting without having to actually spend stock. It's supposed to be closer to the 3:00/6:00 angel kit move in terms of severity, I guess. I don't know, that may or may not make any sense.
I guess it's true that if the patient already took 2-harm from the initial attack, and then the Angel gets 7-9 and picks the 1-harm option, the patient's at at least 9:00 and the Angel will probably be spending stock to heal them anyway. So it's a choice between 1-harm and spend stock, or spend 1 stock. Not much of a choice.
Then again, maybe that's okay - under most circumstances, the spend 1 stock is the obvious choice. If the patient had armor, or if the Angel has a reason to not want to treat their other wounds, or something of the sort, then the 1-harm makes sense as a possible option.

Ten of Swords, these things actually came up in-game already before I made them a threat. Generally I Announce Future Badness in the form of saying there's something frothing in the water off in the distance, and it's coming closer. The Gunlugger used a grenade to blow up the swarm that attacked him, and the Chopper had his whole gang concentrate their fire into the water when they faced this threat. We don't have boats in this game so far - the city's in the middle of a flood, so the streets are filled with water. (I hope we do get boats, though!)
