I like these ideas but there is no chance they will be able to implement them in a good and consistent way throughout the game, because there are way too many variables to account for. You should keep in mind this is not a d&d session but a video game, and you can't improvise on the spot like a human DM. You have to stick to the story you have. So if you need character to lie to you for the story to progress you can't have the player figuring it out mid sentence. You also can't have multiple options for every NPC you can kill in the game simply because it's too much work. The only thing they can do is give us more options than what we have right now, but they can't give us unlimited options.
Welp, my task is to suggest. Their to decide if they can or want to implement all of this/some of this.
But so far… talking about exposing lies in their quest design it wouldn't open totally different routes, it more like would allow to skip some pain on the way. And as I said in my later post in some cases (Kagha) it would just lead to the quest. Imagine we are talking to Kagha the first time, succeding the roll and narrator says "She seems conflicted, she hides something. Maybe you will be able to find the answer if you take a closer look." - and that's it. The player now knows for sure that he can pry a bit and find something.
And about killing via dialog I wouldn't really apply that to enemies, attacking which wouldn't lead to some bloody mayhem (kill you, kill your father, you brother, you mother and that guy which just pass by, who happened to be a quest-giver) or which we are not supposed to kill stealthy. At the moment there are like…*hard thinking*… 2 such enemies? Kagha and Dror. We can kill stealthy some and some others are just surronded by cannon fodder by design.
