This site is run by J.C. Connors, a fervent fan of tabletop games. Here you’ll find a collection of 100% free roleplaying adventures I’ve authored — and the design thinking behind them. I like lots of different roleplaying systems, but you’ll mostly find material for Call of Cthulhu, GURPS, and OSR/D&D. You can also find me on my YouTube channel for RPG tips, reviews, and overviews of these adventures.
I started this site because I often run adventures at conventions, and decided it was silly not to share my work. My goal is always to give fellow GMs all the stuff they need to run a “professional grade” adventure with their friends with as little effort as possible. This means my adventures usually include not just the adventure itself, but also cool handouts, pregenerated characters, and virtual tabletop assets (VTT) for GMs running their games online. Prepping great adventures and GM’ing is time intensive, so hopefully this site helps! If you’re looking to get started, you can find a complete list of the adventures in the Adventure Index.
If you like any of these adventures, all I ask is that you post a comment here and let me know how it went. Find me on Threads @thalcos or Bluesky at @1shotjc.bsky.social
Or, you can always Buy Me a Coffee, and 100% of any donations get invested right back into the adventures here.
