Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
I've created an online insanity generator. It can be used to randomly generate an insanity for Delta Green agents. It is based upon Dennis' descriptions from the PX Pokernight scenario from Polyhedron Magazine. The descriptions decribe in detail what happens when the sanity of an agent (slowly) declines. I hope you like it and find it useful. Keep in mind that it was written for the BRP system.
