-> Crossword Dungeon Jam I created a dungeon inspired by my daily crossword and folks seemed to really like it! So I've made a basic how-to guide & would really like to see what other people create from it.-> TRANS FUCKING RAGE JAM - MAKE SOMETHING NEW AND ANGRY OR SUBMIT SOMETHING OLD AND ANGRY. ART OF ANY FORM IS WELCOME. TRANS RAGE IS THE ONLY IMPORTANT FACTOR-> RPG LATAM JAM 2022 - An event to produce content for Latin American TTRPGs Entry is open for everyone, including non-Latines!Cairn: Forests of Another Name - Cairn has occasionally been called a "forest fantasy" roleplaying game. But what does that mean? Do the characters lose themselves in a deep wood, surrounded by horrific creatures? Or are they brave travellers, exploring the uncharted depths of their world? What is a forest, anyway?International Parks Jam - Design a pamphlet Solo TTRPG around living and working in a national park, or the outdoors in general. You may use the system developed for Evergreen Wilds by Disaster Tourism or come up with your own idea. If you've been itching to get yourself into a pair of leather boots, strap on a weird hat, and explore the natural world within your journal, this jam is for you!Rackham Jam - Write a game or supplement inspired by artwork by Arthur Rackham. It can be serious, absurd, long, short, whatever you want! It can be connected to the story the art is illustrating or have nothing to do with it. It just needs to be inspired by at least one piece of his art. You can find a lot of his art here as well as other places around the internet. The font used in the banner is Chapbook if anyone wants to use it! Promo images available here free to download and use.Together We Jam - Together We Jam is a community event for us to rally together to make old school & sword dream inspired content and systems based on the Together We Go system!LatAm RPG Translation Jam - In short, a translation is like converting content from one language to another while trying to retain as much meaning and style - fidelity to the source language - as possible, while adapting it to make it accessible to the other language - the target language. It's almost a game in itself - do I prioritize keeping the meaning or the rhythm and rhymes? Do I prioritize adapting words and idioms to the target language even if it loses part of its original meaning or do I prioritize keeping most of the original's meaning even if it alienates readers of the target language?Saturday Morning Cartoon Jam - Lets dig deep and crank up the nostalgia, grab your files and lets file off the serial numbers on your favorite childhood cartoons! This jam is primarily focused on tabletop roleplaying games, however any medium is more than fine: video games, music, whatever.Weird Jam Satellite - A jam about nonsensical maps inspired by Weird Spy Satellite. I was looking through this wonderful bot's feed and thought how cool would it be to explore the strange locations it generates. I've made this jam to take it a step further and let everyone create their own unique thing inspired by the concept.10 Page Game Jam - Take a game you've already released and chop it down until just 10 pages remain!game(s) jam - the game(s) jam is an experiment to see what happens when you put two games together. whatever your method: pick pieces carefully, do game welding, mash them together until it's something new. submissions can be full games or just text documents outlining a design space.The MARKED&MADE game jam - MARKED&MADE is the name of the system used for the hit TTRPG, GUN&SLINGER!Syllabus Jam 2021 - Take a moment to think about what your specialty is, what texts shaped your understanding of it, and put it in a reading list. We're all full of hard-won obscure knowledge, let's share it. What better way to start 2021 than by yelling about the things you love and learning in return?Stealing the Jam - Stealing the Throne is a storytelling game of epic giant robot heists. It's zero-prep and GMless, built for action-filled one-shot play. It's also a framework for just about any high-action heist you can imagine. The core engine is simple, easy to learn and easy to hack. And that's what this jam is all about: taking Stealing the Throne's engine or its implied galactic-scale setting and making cool new stuff!Megadungeon Jam - Hello! Welcome to the Megadungeon Jam! This was born out of a bit of a confession on twitter at one of my deeper design goals. I've always wanted to make a megadungeon but had never even attempted to endeavour at how to do so. It seemed many others felt the same, so here's a year-long opportunity to try your hand!
