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 required a a conversion for this trait from other RPG systems, such as GURPS and TriStat, since the players in my campaign already had simular traits as part of their character concepts.
This is a suggested set of rules to advise Keepers/GMs as to how to convert PCs/NPCs from CoC to Nemesis ORE. The main points are that:
1) It makes use of "la belle curve" a lot.
2) Because CoC uses just skill rolls and Nemesis uses stat+skill, Nemesis PCs stats come out somewhat less impressive stat-wise (1d to 3d), but lots of skills! This is okay because Lovecraft's protagonists tend to be less physical and more cerebral.
3) The skill list for Nemesis has been expanded to cover CoCs large number of skills.
4) An example of a conversion is included - see Harvey Walters in all his Nemesis ORE glory!
A new Mundane Trait for the Nemesis system. Below are examples of how much influence his character has with a certain contact, based upon the amount of skill dice he has put into the Influence Trait.
ESP has oddly enough been a sadly neglected set of abilities with Call of Cthulhu. I suppose there are a number of reasons for this, the greatest being that Lovecraft himself did not write about the subject to any great detail and so is considered non-canon by many Lovecraftians. However the actual definitions of the abilities that make up the list of recognised ESP talents are nebulous in the extreme, and then how to handle them in a gaming environment provides the Keeper with certain challenges. This is my attempt at defining the various psychic abilities; there are others on the Internet so if you do not like mine please feel free to seek them out.
Included below are some additional rules and thoughts on using the psychic talent of pyrokinesis in COC/ DG games. I confess to being influenced by comic books when I designed the way pyrokientic flames behave, but those aspects of the talent can easily be discarded if they don't suit your game. Please enjoy!
The current rule is that you can get accustomed to horror when you succeed in your San rolls a number of times equal to the maximum sanity loss of the cause (e.g. 6 times in the case of Ghouls as they cost 1D6 San when you see one). But I think it is far more appropiate that you become accustomed to horror after you've failed your San roll a number of times or lost a number of sanity points, as you then have learned/accepted the true reality of our universe.
