Urban prep is different than traditional dungeon prep. For a dungeon, or a hamlet or keep, you might key every location, but you’re almost never going to do that for a town or city. These are typically run much more loosely, with handwaving around movement through the city.

Most GMs like to prepare those specific aspects of NPCs that are important to them: names, drives/instincts, loyalty, connections, attitude, voice, media models, appearance, faces, actions / GM moves, and system-specific detail.

While different playbooks have unique moves in Apocalypse World for PCs, the GM doesn’t have different moves depending on which playbooks are being used. Masks was one of the first PbtA games, if not the first, to give the Game Master playbook-specific moves. For instance, for the playbook The Outsider, the GM gets the moves: For The Protégé: Many of these moves are tied into the character arc and challenges faced by the corresponding playbooks. Thirsty Sword Lesbians offers three GM moves per playbook: Chasing Adventure does this as well, and I think any GM of […]

Improv Almanac: Dangers and Discoveries for 88 Places is a 467-page resource for the busy Game Master. Did your players take a shortcut through a swamp, and you are looking for ideas for encounters? Are they trying to cross snow-capped peaks, and you don’t want to evoke The Fellowship of the Ring? Are they sailing, and you’ve run out of ideas for what’s on the next island they’ll encounter? The primary way to use this ebook is to look up the type of location your adventurers will be exploring. You’ll find questions […]

In a visit to Montenegro last summer, my wife and I encountered the wall of a castle that listed some of the rulers of the country, which only became independent in 2006. This is a pretty boring way to convey history, and there were no other details but this wall.  Our tour guide had served in the navy of Yugoslavia and told us stories about that navy, and how he missed it. He later discussed life in Serbia and Montenegro, before discussing the current political situation in Montenegro today, making it […]

This post is an excerpt from The Best-Delayed Plans: The Game Master’s Guide to Adventure Prep. Powered by the Apocalypse (PbtA) games—games in the school of design of Apocalypse World—often outline moves and principles for Game Masters. While these are typically intended for use during play, they can also be useful in prep, no matter which RPG system you use. Principles Here are some principles to keep in mind during prep— Moves While principles guide overall play, in PbtA games “GM moves” are the types of responses that GMs make […]

I’ve compiled and updated all of my blog posts on preparation techniques for Game Masters into a free 86-page ebook. Key content: This advice comes from my own experience with 5e, O5R, and PbtA games, so it spans a range of systems, albeit with a focus on fantasy worlds. In addition, I’ve licensed the text under the Creative Commons, so that you can freely adapt any of this material for your own RPG projects, simply by following the CC BY-SA 4.0 licensing terms. You can download the ebook from Itch.io. You […]

While I latched onto warm-up questions as a starting move for Stonetop, some other systems have their own starting moves. Urban/Modern/Fantasy, in which PCs embrace or discover the supernatural, was the first system I encountered with a Start of Session move— Start of Session When you start a new session after your character has significant downtime, say if you primarily focused on your mortal life and obligations or if you furthered your supernatural interests. If you chose mortal, the GM will tell you how one of your Entanglements, Desires, or Dread […]

When preparing to run a PbtA (Powered by the Apocalypse) TTRPG, keep in mind how experience is gained. Many PbtA games have an End of Session move that awards experience points. Make sure you’re giving players chances during the session that align with this move! Here is the End of Session move in Dungeon World: When you reach the end of a session, choose one of your bonds that you feel is resolved (completely explored, no longer relevant, or otherwise). Ask the player of the character you have the bond […]

Because Stonetop wants you to zoom out and see the passage of time, and because players are encouraged to co-create the village and its traditions, I’d often prep questions for my players to think about prior to the session. Initially, I’d send these out with a reminder for our biweekly game. My warmup questions were always to encourage my players to do some world building. Not all players are comfortable improvising in play. So then my players asked to get the questions the day before, so they would have some […]

I lifted one of my prep techniques from the mystery countdowns of Monster of the Week by Michael Sands. These aren’t “whodunit” mysteries but instead mysterious monsters with mysterious agendas and mysterious weaknesses. As the book puts it­— Each mystery has a countdown: this is the sequence of the terrible things that will happen if the hunters don’t stop the monster. The countdown will be your guide to what will be going on off-screen as the hunters investigate. To create the countdown, think about what would happen if the hunters […]

After our Microscope worldbuilding, and before our first actual session of Impulse Drive, I ran a Session Zero based primarily on Stonetop’s Introductions procedure. Stonetop is a hearth fantasy PbtA by Jeremy Strandberg (you can back it here, for a limited time). Each playbook has two customized sets of questions: one set for the player to answer about NPCs and one set for the player as PC to pose to the other PCs. Here’s the process for the Ranger— Stonetop is about adventuring for the sake of protecting and growing […]

One of the great bits of tech from Apocalypse World 2e is the threat map, which provides a concise summary of campaign prep. You can adapt it for other systems as well, if your play centers on a holding or home base. Here’s an example from last year for my Stonetop campaign: D. Vincent Baker and Meguey Baker describe the process of using threat maps as follows: List the players’ characters in the center circle. As you name NPCs, place them on the map around the PCs, according to what […]
