A really underrated RPG is the OneDice system from Cakebread & Walton. It's a ultra-light system, ideal for running one-shots. They are various versions of it available - Space, Fantasy, WWII, etc. Each one is a complete game. They're all quite cheap and easy to run.

It's called OneDice because you only need to roll one D6 to resolve anything.

I just used a OneDice book called B-Movies to run an adventure called Beatniks from Planet X. Some 1950s high school kids had to stop a mysterious meteor from turning their classmates into filthy beatniks.

To prepare for the game, I made some custom character sheets and pregens: https://polyhedralnonsense.com/2023/08/10/onedice-b-movies-character-sheets-pregens/

Last year I also made a custom character sheet for OneDice Pulp: https://polyhedralnonsense.com/2022/07/15/onedice-pulp-mini-review-and-custom-character-sheet-for-a-pulp-adventure-rpg/

I've been playing around with Thálassa, the Cairn-based RPG about adventures in the mythic ancient Mediterranean.

I decided to make my own custom character sheet. It's fillable, and available in US Letter and A4 sizes.

The latest issue of the Cepheus Journal just dropped. It's a free fanzine for the Cepheus Engine RPG (basically OSR Traveller)

It's got an article on cats in space, a mushroom-filled colony world, and a weird mercenary cult.

My contribution is "A Fistful of Spaghetti" - a guide to running Spaghetti Western style games in Cepheus.
