Lovecraft's observation (from his essay, ) that 'The oldest and strongest emotion of mankind is fear, and the strongest kind of fear is fear of the unknown.' The original game, first published in 1981, uses mechanics from, and is set in the 1920s, the setting of many of Lovecraft's stories.

Additional settings were developed in the Cthulhu by Gaslight supplement, a blend of occult and mystery and mostly set in England during the 1890s, and modern/1980s conspiracy with Cthulhu Now.

The protagonists may also travel to places that are not of this earth, represented in the Dreamlands (which can be accessed through dreams as well as being physically connected to the earth), to other planets, or into the voids of space. In keeping with the Lovecraftian theme, the called the Keeper of Arcane Lore, or simply the keeper, while are called 'investigators'.

For inclusion in this list, a supplement must be designed to be used with either the Chaosium BRP Call of Cthulhu rules or the d20 Call of Cthulhu rules produced. This category is primarily for supplements that have already been released (i.e., commercially available or online as free downloads).

CoC uses the system first developed for and used in other Chaosium games. It is skill-based, with player characters getting better with their skills by succeeding at using them for as long as they stay functionally healthy and sane. They do not, however, gain hit points and do not become significantly harder to kill. The game does not use. CoC uses percentile dice (with a results ranging from 1 to 100) to determine success or failure. Every player statistic is intended to be compatible with the notion that there is a probability of success for a particular action given what the player is capable of doing. For example, an artist may have a 75% chance of being able to draw something (represented by having 75 in Art skill), and thus rolling a number under 75 would yield a success.

Rolling ​ 1⁄ 5 or less of the skill level (1-15 in the example) would be a 'special success' (or an 'impale' for combat skills) and would yield some extra bonus to be determined by the keeper. For example, the artist character might draw especially well or especially fast, or catch some unapparent detail in the drawing. The players take the roles of ordinary people drawn into the realm of the mysterious: detectives, criminals, scholars, artists, war veterans, etc. Often, happenings begin innocently enough, until more and more of the workings behind the scenes are revealed.

As the characters learn more of the true horrors of the world and the irrelevance of humanity, their sanity (represented by 'Sanity Points', abbreviated SAN) inevitably withers away. The game includes a mechanism for determining how damaged a character's sanity is at any given point; encountering the horrific beings usually triggers a loss of SAN points. To gain the tools they need to defeat the horrors – mystic knowledge and magic – the characters may end up losing some of their sanity, though other means such as pure firepower or simply outsmarting one's opponents also exist. CoC has a reputation as a game in which it is quite common for a player character to die in gruesome circumstances or end up in a mental institution.
