One-Shot Prep: Structuring My Notes

I’ve spent quite a bit of time oscillating between different ways of presenting my prep for one-shots. Particularly at conventions, I like to have all my information to hand in an at-a-glance format, and so it helps to have a consistent structure – but it’s only in the last couple of months that I’ve settled on one. You can see this format in Gringle’s Pawn Shop, my 13G adventure, and I’ve used it for all of my recent ‘trad’ one-shot games. Here’s what it looks like

This starts with the ‘pitch,’ which is sometimes the game description that I sent off to the con / printed out on a sign-up sheet to advertise the game. I always begin my prep by pasting this across – sometimes I’ve written this text several months earlier and need to be reminded of what I said – it’s a useful creative constraint!

Then there’s overview of the background of the adventure in one paragraph maximum. I grew up on Dungeon Magazine adventures where you’d get a whole page of background explaining why the goblins settled in this particular tomb, what happened to the dwarf king who used to be buried here, but I don’t need – or care – about all that guff. Brevity is a strength, and by writing this first it helps to structure the game in my mind.


This section is a recent addition to my prep, and I’ve been surprised by how useful it is to have all my NPCs in one place. On one level, it’s useful to check there are a reasonable number of them – I think that 3-5 NPCs for a one-shot is about the sweet spot for the players to remember and interact with them all – and it’s very easy to prep a one-shot with more, or fewer, than these. Generally, fewer than 3 and the players don’t get enough chance to roleplay outside their own party, and more than 5 are too many for the players to remember and interact with meaningfully.

They get a really brief description of anything distinctive about them, and any roleplaying notes if I’m going to be doing a silly voice for them. It helps with all of these to have really simple physical notes on them – a blue dress, an eyepatch, a gravelly voice – just one thing that the players might remember about them.


Then I list each scene out – each gets a description of what happens at the start, and any game stats / information needed. These aren’t always linear – as I’ve posted before, I like to have a set middle and end and be a bit more loosey-goosey in the middle (the ‘swell’ is described here), so often these scenes can proceed in any order. I like to get game stats here as well so it’s all in one place, which I usually snip from .pdfs – including any game mechanics that are likely to get used. Obviously the games shared on here won’t have the snipped game statistics, but it’s worked much better for me to have each scene with everything on it, so there is only one document that I need to flip at the table.

A tip that I picked up from the Smart Party is to add descriptors to any group of similar monsters – especially as I always run combat as ‘theatre of the mind’ without minis, it’s useful to be able to refer to ‘fat goblin’ and ‘eye patch goblin’ during the game.

Except for short scenes, these are often printed out one to a page, and then the whole document is stapled (and printed out single-sided – flipping sides of paper can be fiddly at the table in the heat of battle). Any information or clues that can be found in scenes is put in bullet points so it stands out from the rest of the information.

So that’s my current format for one-shot prep. Later this week I’ll post a fuller example – of a one-shot I’m prepping for Starfinder where you have to liberate android gladiators from the slave pits – but for now, what format do you use when prepping one-shots?

  1. […] In this first instalment, I present to you the adventure itself – along with the attached beer mat synopsis of its structure. In my next post, as well as providing a .pdf version of this, I’ll try to dissect how I’ve tried to balance investigation with action. The setting, on the off chance you’re not familiar with UJ’s three city settings, is Bellegard, a pseudo-New Orleans, in 1930. The basic structure of these notes, as you’d expect, is like I mentioned here. […]
