The World of Darkness is a Gothic-Punk setting, using the Storyteller System, published by White Wolf from 1991 to 2004. While not a real game line in its own right, it is the shared setting for a myriad of other games. The setting closed with the long-promised end of the world, and in 2004 White Wolf launched a new World of Darkness.
Beginning in 2011 with the release of VTM: Vampire: The Masquerade 20th Anniversary Edition, White Wolf began the "Onyx Path," which started with the release of new Classic World of Darkness products concurrently with the current World of Darkness. Some of these products pick up series where they left off 10 years ago or more.
To differentiate between the two settings, most fans took to dubbing the original the "old World of Darkness" compared to the "new World of Darkness". With the Onyx Path, White Wolf officially branded the original as the Classic World of Darkness, while the current is simply the World of Darkness.
These three games heralded the end of things, from three different perspectives: the dead, the fallen, and the humans who fight back against the darkness.
Games which, while they presented separate fully-playable concepts, often required one of the main games in order to have the complete rules. The first fatsplats.
