So I'm setting up a Call of Cthulhu game and I'm having some trouble choosing between all of the many ways I can run this. My friends say they would like to be a little more than the mundane average joe as they are used to running fantasy themed rpgs and not really anything close to horror. This is my first Call of Cthulhu game and want to make it entertaining for everyone. I have thought about Chronicles of Darkness/Hunter: The Vigil and making it CoC themed. I have also thought about D20 CoC (which uses DnD 3.5 rules) with Pathfinder rules. I am however a bit nervous about using the Chaosium 7th edition CoC since I've read a great deal of the 6th edition and am pretty much used to that way. Is there a way to use the 7th edition rules and make them more than the average joe?
