We started modifying the game after our first session and after Zombies, Aliens, Gods and Machines we are still modifying. The system begs for house rules honestly. I don't mean that as absolute condemnation, in fact the system is so streamlined that it makes house ruling pretty easy, but we did find it necessary to get a clean game out of it.
Just wondering what kind of house rules you guys are using?
Heres one we added first game -
Cross category Stress and Feature/Trauma Effects - wherein Stress can affect another category besides the one being used for a task and the effects of a Feature or Trauma can come into play where categories other than the typical one are in play.
For example - a guy has to shoot his buddy that just turned into a zombie and suffers a Stress during the attack - we stick it on Mental as anguish for having to shoot his friend. OR - a character has "Long Distance Runner" as a feature, typically a physical boost, but he is permitted to use the bonus dice in a Willpower roll when trying to stay awake during guard duty as a product of his self discipline.
