What It Is

1Shot Adventures is a tabletop role-playing game resource blog run by J.C. Connors, with a very clear focus: sharing the author’s 100% free one-shot TTRPG adventures and explaining the design thinking behind them. The site’s content mainly covers systems such as Call of Cthulhu, GURPS, and OSR/D&D, while also spanning genres and themes including horror, fantasy, cyberpunk, mythology, and pirates.

Core Features

The site’s greatest value lies not in ordinary articles, but in ready-to-use game packs. The author emphasizes helping GMs run “professional-grade” adventures with as little prep as possible, so many releases include not only adventure text but also handouts, pregenerated characters, and virtual tabletop (VTT) assets. The articles also break down common GM challenges such as random encounters, clue placement, atmosphere building, and dungeon design, making them highly useful for anyone looking to improve their module-writing skills.

Pricing

The site’s content is presented as free, with no subscription wall or paid download information. The author accepts support through Buy Me a Coffee and states that donations are reinvested into adventure creation. As such, it feels more like a public-interest resource site by an individual creator than a commercial module marketplace.

Pros and Cons

Its strengths are that the content is complete and highly practical, especially for game masters who need to prepare sessions quickly. The author also openly explains the design logic, giving it strong learning value. The drawbacks are also fairly clear: the site is primarily in English, so Chinese-speaking GMs will face translation costs; as a personal blog, its categorization, filtering, and interactive experience are not as polished as larger platforms like DriveThruRPG or itch.io; and the content is not public domain, so redistribution, adaptation, or commercial use requires checking the specific licensing terms first.

Who It’s For

It is very well suited to GMs, Keepers, DMs, tabletop community organizers, and anyone preparing offline events or convention one-shots. If you are looking for ready-made Cthulhu, OSR, or fantasy adventures that can be run in a single evening, or if you want to study the structural design of strong short-form modules, this site is worth bookmarking.

Access in China

The main site is usually directly accessible, but its external ecosystem—such as YouTube, Threads, Bluesky, and Buy Me a Coffee—may be unstable or require a proxy in mainland China. If you only need to download and read the text resources on the site itself, the impact should be limited. Overall, 1Shot Adventures is a small but excellent free TTRPG resource site.
