Based on the works of H.P. Lovecraft, the tabletop RPG Call of Cthulhu was created by Sandy Peterson in 1981 and published by Chaosium. Incorporating elements from Lovecraft’s original work and the expanded Cthulhu Mythos, Call of Cthulhu utilizes Chaosium’s Basic Role-Playing (BRP) system and Sanity system. Primary set in the 1920s or the Modern Era, the system has inspired numerous offshoots, including Cthulhu by Gaslight (set in the 1890s London of Sherlock Holmes), Cthulhu Now and Delta Green (a military-focused Cthulhu setting), as well as historic and futuristic settings. Call of Cthulhu’s latest release is the 7th Edition rules set.
