The World of Darkness is a trio of settings for supernatural and horror tabletop role playing games. It was originally developed as the background setting for the original 1991 release of Vampire: The Masquerade. The series gained some popularity in tabletop circles as an alternative to a rather scant selection between an adaptation of H. P. Lovecraft's Call of Cthulhu and the Ravenloft setting of Dungeons and Dragons. While Ravenloft is medieval and Call of Cthulhu is set in the 1920's, the World of Darkness is mostly our own modern world with plenty of supernatural details added into the recipe, with some spinoffs set in various historical eras.
Vampire: The Masquerade is the most popular game set in the World of Darkness, but some other popular releases include Hunter: The Reckoning, Mage: The Ascension, and Werewolf: The Apocalypse. The naming convention becomes easy to identify quite quickly. Multiple video games have been released in the World of Darkness, including three focused on Vampire: The Masquerade. The first one was an action RPG developed by Nihilistic Software and released in 2000 called Vampire: The Masquerade - Redemption. This game was a modest success, enough to greenlight a sequel. Troika Games developed this sequel, called Bloodlines, with Activision publishing both Redemption and Bloodlines, both exclusive to PC.
