I’ve always been a a big fan of Edgar Rice Burroughs’ Barsoom novels, set on his dying, fanatstic version of Mars. There has been a good number of role-playing games set on Barsoom. Here’s the list I’ve put together so far.
Let me know if I’ve missed anything in comments.
John Carter of Mars

This is the big one. John Carter of Mars – Modiphius’ lavishly illustrated RPG, with the official backing of Edgar Rice Burroughs estate. It uses the same 2d20 system that their other games use (Conan, Star Trek). They’ve published multiple supplements, minaiatures, tile sets, and a GM screen.
Even if you’re using another system, anyone interested in gaming on Barsoom needs to pick this up. There’s a lot of background material for running a game on Barsoom, in a clear usable format.

Warriors of Mars: The Warfare of Barsoom in Miniature

In 1974, Gary Gygax and Brian Blume put out wargaming rules for Barsoom, including individual man-to-man combat. You can get it for free at the Internet Archive.

Dungeons & Dragons: Warriors of Mars

Found at https://grey-elf.com/
This is a free, fan-made supplement designed to run Barsoomian games using original D&D rules. It’s even formatted to look like one of the original D&D books.

Edgar Rice Burroughs’ Mars: Shadows of a Dying World (An OGL Guide to Monsters, Races, and Beasts)

Skirmisher Publishing put out an OGL version of Barsoom that should
work with most D20 systems.

Heroes of Mars

Jeffrey Kazmierski put together a version of Barsoom for the FUDGE system. It’s no longer online, but you can still see it on the Internet Archive

A Dream of Mars

Little Red Goblin Games has a cheap ($1.00) adaptation of Barsoom for Pathfinder

Lords of Mars


Ray Otus made a simple hack of Tunnel Goons set on Barsoom. It’s only a few pages long, but includes rules for mass battles and airship conflict. I made a character sheet for it here

In addition to games set explicitly on Burrough’s Mars, there are many games set on fictional versions of Mars that are clearly inspired by Barsoom.
Warriors of the Red Planet

Night Owl Workshop puts out several games using Original D&D-style rules for variety of genres, including Warriors of the Red Planet. It’s set on a thinly-disguised Barsoom. It has rules for airship combat, underground exploration, and sorcery. It has a particularly nice “Appendix N” section, listing almost every Sword & Planet novel ever published, including a lot of obscure stuff more casual fans probably haven’t heard of.

Revelations of Mars

Exile Games had an expansion to their Hollow Earth Expedition set on their pulpy version of Mars, using their Ubiquity system.

Thanks for this exhaustive list. I only know the more recent btiyles, the one from Modiphius, obviously, and also both Savage Worlds and Hollow Earth rulesets.
