I was listening to another actual play podcast yesterday and they were playing a little indie game I didn't remember ever having heard of called
Soth, where the players play small-town cultists trying to summon a dark god named Soth through a series of ritual sacrifices while the GM accumulates a Suspicion resource based on their actions and spends it behind the scenes on investigatorial efforts to stop them. Everyone has ties to regular people in the setting but also have Compulsions and Clarity that betray their increasing madness. It's kind of A Dirty World crossed with Fiasco and mirror-image Call of Cthulhu and it seems like it would be very much the sort of game that Ross or Caleb could get serious mileage from in one-shots. I'd love to see that happen.
