You would need to edit the dialogs for people and modify the attributes for possible decisions from there. With a question or objective giving options I will go at this from a more complex system then what dragon age uses. This system is of course from Mass Effect 2. Each character likes a certain type of thing and so for a quick example of how this plays out on dragon age with the sacred ashes.. Piss on sacred ashes:::: take sacred ashes and leave it alone::: You would need to go through each dialog option and modify the affection change for each affection modifying choice. For a party conversation style it's a hell of a lot easier with a simple Option A: - affection, Option B: + affection, Option C: no change
