Apocalypse World, the OG!
Did you know that some early PBTA games used to have Blank world as a naming scheme? it never really caught on
Touchstones: Fallout, Mad Max
Genre: Post-Apocalypse, Drama
What is this game?: Apocalypse World is a roleplay focused post-apocalyptic roleplaying game, its also the game that spawned the very popular PBTA framework
CWs: Apocalypse world deals with many dark themes, it's considered an "R-Rated" game citing Language, Sex, and Violence, it also features Mind control, mentions of drug use, and general post-apocalyptic horribleness, however I will attempt to stray away from those themes if possible
How's the gameplay?: OK, I'll likely actually link back to this review a few more times as we talk about other PBTA games, just so we can skip explaining the PBTA gameplay every time, so we're gonna try to be pretty thorough this time
Apocalypse World's primary mechanic focuses on the use of Moves, Playbooks, and a 2d6 resolution system, where 1-6 is a miss, 7-9 is a weak hit, and 10-12 is a Strong hit, however your roll will always progress the story in some way, this way even failure can be fun!
Moves trigger when doing specific actions, and they all interact with mechanics in some way, the prototypical move in Apocalypse world reads like this: "When Narrative trigger: gameplay effect", then this will either help you with a roll around the gameplay effect, or have you roll for a new gameplay effect, whereupon it'll read like this: "On a 1-6, Failure with consequences, on a 7-9 Success with Consequences, on a 10-12 Success with no consequences"
Moves will usually add a stat to them, Apocalypse world's stats are Cool, Hard, Hot, Sharp, Weird, and HX, HX being an asymmetrical stat determining your relationship with other characters.
Playbooks are your character's narrative role, it will give your characters their narrative abilities, gameplay moves, relationships, appearances, basically everything about your character beyond things such as name (and even then, some games remove THAT distinction too), you pick one at the start and generally stick with them the whole game, think of it as a class, in Apocalypse World specifically every playbook has a "Special", a move that generally triggers when characters have sex, this might seem like the type of thing that other games in the framework dumpster pretty quick, but you'd be surprised it actually took a bit for people to get rid of that one
What's the setting (If any) like?: It has one Ok, in all seriousness, Apocalypse World's setting assumes you're playing in an edgy, presumably nuclear, mad max inspired post apocalypse, characters are grimy, aesthetics are leathery and gritty, mutations are common, and shit's BAD. Otherwise, feel free to work on the specifics, maybe you just want to play 1-to-1 fallout, or maybe you want to create your own fully original apocalyptic version of The Butt, Coventry, UK
What's the tone?: Dark. Apocalypse World makes it very clear that the world sucks, and the characters (probably) suck, while you could play a ragtag group of do-gooders, the game assumes a morally gray cast in a world that is actively hostile towards them. Apocalypse World's tone is, not for the faint of heart
Session length: Variable but 3 hours is usually enough to do quite a bit
Number of Players: 3 Minimum, but obviously more can help
Malleability: Apocalypse World's setting is generic to non existant, letting you play a ton of post apocalyptic settings, while branded apocalypses like Fallout or Mad Max might be difficult due to the inclusion of overt supernatural elements, you could really do any nuclear apocalyptic setting within this framework.
Resources: Apocalypse World has quite a few resources just due to being one of the oldest PBTA games, a google sheet exists, I've seen some short scenarios, and the game provides you with Move and Playbook cheat sheets, fan playbooks also exist and there's some pretty good ones if you look around enough, it's not a lot but it's enough for what the game is
And here's the big cheese! While most modern PBTA design comes from Monsterhearts and Masks, this is the game that started it all, its gritty and very rough around the edges, but I still really like it
