Around the very beginning of the game, as my companion and I wandered around getting our bearings, I found a book next to a corpse. My character read it aloud to the other character: apparently this man leaped from the top of a cliff because his Gods told him if he did, he would fly. My partner's character said that the man was obviously a fool, and I was offered a choice of dialogue options. I could either agree, disagree, or not make up my mind one way or the other. I disagreed, and said that sometimes you have to trust the gods. My character gained two points of Faith, my partner's gained two points of Cynicism.
You can read more about the Party Dialogue System in the Kickstarter, but it was constantly enjoyable to play. When the characters disagree, there's a hidden system that measures their persuasive abilities against one another and you get to see the outcome. There may have been more than one occasion I overruled my partner and insulted some guard's mother just so I could test out the combat system.
