A list of fantasy and science fiction literature that inspired Dungeons & Dragons.

Featuring authors such as Robert E Howard, Fritz Lieber, Jack Vance, Michael Moorcock, HP Lovecraft, Clark Ashton Smith, and Leigh Brackett. These works were primarily written between the 1930s and 1970s, when the genres were still taking shape into what we know today. They’re known for their action, weirdness, and deep vocabulary.

Today, you can find such titles on the shelves of used bookstores. Typically appearing as beat up ‘70s paperbacks with faded text printed on pulpy, yellowed pages.

In the Tabletop Role Playing Game community, this is a vibe modern creators love returning to.

This July, join us for an itch jam that pays homage to this retro pulp fantasy.

The second annual Appx. N Jam!


  • Your adventure will be assigned a made up Appendix N book title.
    • Your submission must use and reflect the title assigned to you.
    • We’ll send your randomly determined title on July 1st via our MASTER LIST.
    • If you sign up after the jam has started, you will receive your title within 24-48 hours.
    • If your title doesn't work for you, you may request an alternative, but we STRONGLY suggest working with the title given.
    • If your title seems familiar, that's because we're reusing titles from last year that were given out but no entry was submitted for!
  • Your submission must be a ttrpg module of some kind.
    • Heist, Point Crawl, Puzzle or a good old fashioned Dungeon are all great options! Do whatever!
  • The module must be no more than FOUR A5 Pages.
    • A5 is 5.8 inches by 8.3 inches, so you could think of this as both sides of a letter sized sheet of paper.
    • Cover is not required, but if you chose to include one as part of your PDF it will count toward the page limit.
    • Trifold or 8 A6 page formats are allowed, as long as the physical size does not exceed the requirements.
  • There is no predetermined TTRPG system the module needs to be for. Make your module system agnostic or for a system of your choosing.
    • If you use a system we would request a D&D edition, derivative, or spiritual successor, but this is not mandatory.
  • No bigotry, sexism, or hate of any kind is allowed.
    • While we understand the old pulps can contain inappropriate content, if it wouldn’t fly in a book today it’s not worth referencing.
  • No AI content of any kind is allowed.
    • We want to see what you come up with! Creating it on your own is part of the fun!
  • Feel free to charge for what you make.
    • A free digital copy will need to be provided to our judges.


Entries will be evaluated on 4 categories: Writing, Visual Design, Gameability, and Theme.

Writing: the strength of the prose. What kind of ideas are present in the writing? Do they fire your imagination? How well is this information conveyed? Is this module telling you everything it needs to? Is the text meandering or to the point? 

Visual Design: the art and layout of the module. How striking are the visuals? Does the art represent the text? Is information findable on the page? Are elements where you expect them to be? Do the color or contrast heighten the work?

Gameability: the module's ease of use. Does this seem easy to run? Are the concepts accessible? Would this require additional materials to work? How much prep time would this module require? Do the themes above come together in a helpful way?

Theme: the retro vibes. If this module were a book, would you expect to find it on the original Appendix N list? How faithful are it's ideas to the weird fiction and science fantasy genres? Does it use elements from those old stories? How does it adapt them for the needs of a modern audience?


Making modules isn't easy and we want to make sure the best ones get rewarded.

  • Judges Pick: $100
  • Audience Pick: $100
  • Judges Picks Per Category: $50 each

Last year we were felt like the audience pick didn't nearly get rewarded enough for its excellent quality. So we've decided to put the audience and judges pick at parity with each other. We also really wanted to make sure outstanding entries in each category got more recognition, so we have replaced 2nd place with an award for each category. While participants can vote on best category (as last year) the category prizes will be determined by the judges panel.

Please note that money will be sent via PayPal.


Our panel of judges are all cool people in the rpg community. They range from writers to commentators in order to give insight into different aspects of the submissions. 

Our 2026 Panel of Judges Are:

We want to make sure you have everything you need to put together your adventure!

Want more Appendix N specific resources? We've made a Google Drive with some curated free fonts, textures, and images we think work well.


Last year we were blown away by the volume and caliber of submissions, as well as the support creators gave to each other! We saw the community come together in so many positive ways. From sharing ideas, to making resources, to design feedback, to hyping up fellow entries. Big names in the space took the time to help out new creators. This meant so much to us as hosts of the competition and we wanted to take a moment to extend our heartfelt thanks. 

We cannot wait to see this years submissions!
