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 ran 5e with 8 to 10 players for two campaigns. The first campaign was an open table at our FLGS (Friendly Local Game Store). That campaign quickly grew from 3 players the first session to a peak of 12 players once (on which occasion we split into two separate tables with two DMs). Given the shortage of DMs, you too may find yourself with lots of players. My key advice: In general, just embrace the chaos! Roll with the punches! All my plans went out the window fairly quickly […]

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 […]

The Road goes ever on and onDown from the door where it began.Now far ahead the Road has gone,And I must follow, if I can. –       J.R.R. Tolkien I remember reading The Fellowship of the Ring on the school bus, arguing with my friend. I loved the songs and poems, but my classmate said they were awful and skipped right over all of them. Hey dol! Merry dol! Ring a dong dilly! He’s got a point that some of these are silly. Still, I’ve found there’s a […]

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 […]

Having heard great things about using the Microscope RPG for collaborative world-building, I knew that I wanted to kick-off our new science-fiction PbtA campaign with a Microscope session. Heck, our planned setting is literally the first scenario listed on the website: “Humanity spreads to the stars and forges a galactic civilization”! (Fantasy RPG players, the next two are “Fledgling nations arise from the ruins of the empire” and “An ancient line of dragon-kings dies out as magic fades from the realm.”) Since we would be playing online, we used the […]

In my book Langmaker: Celebrating Conlangs, I have a chapter on creating a naming language. Namelangs are small languages intended primarily for naming people and places in an imagined world. As such, you don’t need to create a grammar or extensive vocabulary, just a short dictionary. Heck, you don’t even have to be formal about what sounds are included in the language and how they are combined (phonotactics). Now much conlanging is for fun and private amusement, but I ran into a problem with Denju, my naming language that I […]

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 […]

DMs and GMs have a lot of different ways they can prep for role-playing sessions, as I’ve learnt over the past three years: These days I’m still using the core of the Lazy DM outline, supplemented by the other techniques. Sometimes I find switching prep techniques just helps be to me more creative and motivates me to actually do some prep! Which, of course, is what I should be doing now! Updates: These essays are now collected in my free ebook, Best-Delayed Plans. Post updated 2022-04-03 with link to threat […]
