The Call of Cthulhu roleplaying game is set in the world of H. P. Lovecraft and places the characters in direct confrontation with the forces of the Cthulhu Mythos. Most commonly the setting is in the 1920′s although earlier and later settings are covered by the rules. The game is somewhat unique in that the ‘heros’ are not particularly special. They are usually everyday people who happen to be caught up in things. The games are also often very focused on an investigation of some occurence, or some great evil. Investigators (as the heros are called in the game) are often called upon to uncover the evil machinations of dark cults, or the malevolent workings of deranged madmen.
