While we do plan to track some lies individually, most of the time the choices are ambiguous between honesty and deception (they’re choices about what to say or do, not choices about what your intentions are). In these cases, there will still likely be different consequences depending on what happens later. For example, if you string Adriana along in such a way as to earn a lot of approval and friendship with her, and then later defect to the Iskendi, fairmath means that the same % hit to her approval will do more damage to someone who has a lot of it to begin with, nicely reflecting the insult on top of the injury, so to speak.
It’s also highly likely that there will be some dialogue/action variants based on how much approval one had before the betrayal: she’ll act differently if she trusted you somewhat than she will if she’s totally not shocked by the decision. So while in most cases we won’t be tracking individual lies, we’ll certainly be accounting for the patterns, and how surprising the NPCs would find the PC’s actions based on what they’ve said and done previously!
