I will use an example to illustrate my question. If I wanted to make my player`s characters more complex and support/motivate my players to actually role-play, then I would take the char belief concept/rules from Burning Wheel and add them to my game. Done!
So, my question is - can similar things be done to make my Call of Cthulhu game more horror-oriented?
I have the problem that the actual rules do not help me create a horror game. 100% of the time if my players get "scared" it is because of the chars I made, the scenes I framed or the likes, but never has a player said to me: "Wow, those rules/mechanics really made that scene tense!" Never!
My group usually wants me to run a Lovecraftian cosmic horror campaign and I have been using the rules as they are written (CoC 7th edition). I usually use characters, scenes and improvisation for creating horror in my games, therefore, I have not tried to really experiment with different home brew rules, but I would like to try now... since the game rules do not help me at all. I hope that helps you to see where I am coming from.
Ideas?
Thanks in advance!
