Although some gamers may be familiar with Call of Cthulhu, many are unaware of the tremendous legacy the H.P. Lovecraft-inspired game bequeathed to the role-playing game industry.
Call of Cthulhu was one of the first role-playing games to have a literary legacy. Because Chaosium publishes both the role-playing game and collections of Lovecraftian fiction, the game is treated on equal footing with the books that inspired it. Daniel Harms' Cthulhu Mythos Encyclopedia includes entries that span the entirety of Chaosium's catalogue, including both games and fiction and mixing the two. As a result, Chaosium's gaming supplements have helped shape the interpretation of Lovecraft's Cthulhu Mythos to subsequent generations of gamers.
Dungeons & Dragons owes much to Call of Cthulhu. This is most evident in its monsters: Ghouls, Kuo-toa (Deep Ones), Mind Flayers (Star Spawn of Cthulhu), and Black Pudding (Shoggoth) all are directly or indirectly inspired by their Lovecraftian counterparts. ^ Jacobs, James (October 2004).
