John Carter¸ Warlord of Mars
A pulp sci-fi miniatures system and RPG¸ based on the novels by Edgar Rice Burrough's. It is primarily wargame in flavor¸ but does provide background on Barsoom and its cultures. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. KimThe game rules are very early D&D/tactical man-to-man wargame in style. They are interesting from a historical point of view. The majority of the book is campaign background for Barsoomian adventuring. Cultures¸ physical descriptions and numeric equivalents are all provided.
