I found a good and fun way to make use of the often useless Cult Encounters (and in effect, the Corruption cards). I pick one monster from each dimensional symbol except the star and triangle. Place it in the monster cup and have someone randomly draw one. What happens is that for the rest of the game, whenever a monster of that dimensional symbol is defeated, you draw a cult encounter card. I made additional rules to it. Whenever a cards is the kind that forces to you to decide between getting the effect or moving to the street, you just place that card at the bottom and draw one more. Putting into place the idea that "move to the street" is changed "draw another card". You are not considered to have the Cult Membership, so any card and effect that says that you should lose it is pointless. The idea behind this is that the Ancient ones watch out for their ilk and you have to be careful in killing willy-nilly.
What do you think?
So far, my friends enjoy the sudden boost in difficulty and we spend more time planning out attacks. Also, to avoid the bulk up of one character, making the entire party active in the whole operation.
