I found a game system once that I'm trying to find again. A few minutes of Googling hasn't availed me any success. The main features I remember are:
It was a modern-day Lovecraftian setting.
The characters were potential cultists, who Cthulu wanted, but who weren't cultists yet.
The conflict resolution mechanic involved how much that character cares about otherworldly things; by caring more, they succeeded more often, but if they care too much, they become a cultist.
Player table talk was audible to the characters in the game. This is a specific game rule that was in the book, and not just the way the game was played at a particular table.
There we're creatures called Apartment Liches that cared so little that they stopped needing food or water, and didn't age.
The game had a tongue-in-cheek humourous style to the writing.
Every adventure started with a Headline, something interesting that the characters see in the newspaper.
It may have been called Apathy.
