Last year, I made a small character sheet for Lords of Mars by Ray Otus, a rules-light RPG based on Edgar Rice Burroughs’s Barsoom series of pulp novels.
The original versions of these were small (5.5 x 4 inch) to match the size of the rule book.
I’ve now made a version that’s letter-size, with a little more room, and a quick reference for the rules.
