CoC's Sanity-like rules for the nWoD?

Question

Is there a good adaptation of Call of Cthulhu's Sanity rules to the Storytelling system of the new World of Darkness (possibly replacing Morality)?

(Edited the title to make it more precise.)

Answer 1

The "Forbidden Lore" system from World of Darkness: Mirrors (p.28-32) is cognate to the Sanity system; characters garner Insanity points and lose rating in their Reason score. Along the way, they acquire Mental and Social penalties and gain bonuses to Occult endeavors — including the ability to use supernatural powers without gaining the associated template. The correspondences seem fairly close.

Answer 2

To my mind, CoC Sanity rules are quite easy to use as is. For instance you can use the sum of the mental characteristics as a base and multiply by 5 or 6 (depending on how crazy your world is) to get the starting sanity and then use the typical CoC Sanity rules.

I think something like that may work.

Answer 3

Personally I'd have a look at Unknown Armies mechanics, which to me look more nuanced (and I believe can be retooled for different game systems, too).
