Here’s a nice photo essay on building a red planet terrain board.
Under the Moons of Zoon is a John Carter of Mars inspired free RPG.
The author writes:
Under the Moons of Zoon (also UTMOZ) is the grand child of a previous project of mine Kalevala.
Kalevala was originally born in 1991 as a one of many cheap italian role playing, live action and board games collectively known as “Giochi del duemila”. Of all these mini-games Kalevala was chosen to be published in Kaos a games’ magazine published at the time by Nexus Games.
Kalevala used a sort of universal mechanic based on 1d20 and used a free-form magic system simialr to that of early versions of Ars magica.
Later on -circa year 2000- Kalevala got translated to English and completely revamped to use only d6s for publishing under Demian Katz’s Aegis.
While rewriting kalevala I had the distinct impression that the new system had potential, and already at that time I had a compulsive need to write COMPLETE rulesets, as complete as my beloved D&D Rules Cyclopedia.
UTMOZ was born from the revamped system for Kalevala, adding psionics, weird science and much more and removing magic. The main inspiration for the background setting is John carter of Mars by Edgar Rice Burroughs.
EGBZine is an online archive of more than 10,000 pages of Edgar Rice Burroughs goodness — stories, articles, art and more. If you’re contemplating (as I am) a John Carter of Mars game, this is a good place to start.
It seems that back in the 1930s, the son of Edgar Rice Burroughs set out to create a cartoon series based on his father’s John Carter of Mars series of novels. Unfortunately, the series never got off the ground. Some initial work on the series survived, however, and you can see it in the YouTube video below:
Edgar Rice Burroughs’ Barsoom novels are among my favorite guilty pleasures. Sean K. Reynolds has a page with material, including monster and character profiles from his d20 Barsoon campaign.
