basis and is set in the 1920s, the setting of many of Lovecraft's stories. Many supplements expanded the game's setting beyond the original 1920s to different historical periods and otherworldly locales. The Cthulhu by Gaslight supplement blends the occult and Holmesian mystery and is mostly set in England during the 1890s. Cthulhu Now and Delta Green are set in a modern/1980s era and deal with conspiracies. Recent settings include 1000 AD (Cthulhu: Dark Ages), the 23rd century (Cthulhu Rising) and Ancient Rome (Cthulhu Invictus). The protagonists may also travel to places that are not of this earth, such as the Dreamlands (which can be accessed through dreams as well as being physically connected to the earth), Carcosa, other planets, or the voids of space. In keeping with the Lovecraftian theme, the gamemaster is called the Keeper of Arcane Lore ("the keeper"), while player characters are called Investigators of the Unknown ("investigators").

In Call of Cthulhu, players control ordinary people: investigators, typically in the game's default historical 1920s setting, seeking to solve and uncover paranormal mysteries, usually linked to the Cthulhu Mythos, and survive its deadly creatures that are harmful to their lives and the human psyche. At its release in 1981, the game was notable for its emphasis on psychological horror, investigation, and character vulnerability rather than combat and heroic adventures, departing from the conventions of many contemporary role-playing games. Widely regarded as a pioneering horror role-playing game, it influenced numerous later games and helped establish horror as a major tabletop RPG genre
