Kenneth Hite argues that the long-running, H.P. Lovecraft-inspired Call of Cthulhu franchise differs from traditional tabletop role-playing in its focus on suspense rather than character growth. Hite's analysis suggests that in its origins and emphasis on narrative structure Cthulhu is a highly literary game.

"A scenario in Call of Cthulhu can be organized like the layers of an onion. On the surface, suppose that the scenario looks like it's about a conventional haunted house. It might even look like a hoax. (...) The sixth edition version is slightly less proscriptive than the first, substituting "can" for "should," and being headlined "An Example of A Plot" rather than the sterner "How to Set Up a Scenario" from the first edition.The sixth edition also provides a sidebar with step-by-step guidelines for "Building a Scenario":(...)1) A mystery or crisis is posed. . .2) The investigators become linked to the problem. . .3) The investigators attempt to define the mystery. . .4) The investigators use the clues and evidence to confront the danger. . .5) The mystery or problem is solved. (Ibid., 136)."
