Last time I started a thread like this, Paul Czege posted and more or less gave me the mechanic I was looking for on a silver platter. Let's see if lightning strikes twice.
I've always loved Sanity mechanics, especially the one from Unknown Armies that builds of the CoC one and makes it 100x better.
For my game, Dark Days, I'm modding that mechanic into something else, by using the game's focus points (Darkness and Madness/Despair) and it works great, but I feel it's not enough. It's almost as if I skinned the UA sanity mechanics with different names and purposes.
So what would the perfect sanity mechanic look like for you? Are there any others out there besides UA and CoC that use them?
Pitch me some!
