Having more options for your RPGs is never a bad thing. In this instance, those of you that want to play a game in a modern setting with heavy occult overtones will want to check out Secretum Mundi. It's to be an encyclopedic tome of occult groups and individuals, as well as potential plot hooks, all being created system agnostic, so you can just drop it into whatever game you migth want. The book is up on Kickstarter now.
From the campaign:
Welcome to Secretum Mundi. This project is to create and publish a encyclopedic-style supplement for the Esoterica Roleplaying game, or for any other roleplaying game that focuses on the occult and magic in the modern world. The book will contain a range of alphabetized entries on occult individuals, places, events and items, the majority of which will have plot hooks that can be used to create adventures. Also, many of the entries will interlink (i.e. reference each other), so that several entries can be used to create a mini campaign. The book doesn't contain any rules and is therefore system neutral, so it can be used with any occult-themed roleplaying game.
The Kickstarter is more than 2x funded with 25 days left to go.
