Lines for some stale linear plotline arent all that interesting especially after youve heard it once or twice
Better is the old classic RPG lines like a Royal Greeting when addressing your advisors: "Yes Sire?", "Your wish is my command" -kinda stuff.
When you are a lowly nothing having the opposite -like voices of disdain but keep it general and reactionary to the player. Also audio effects like a Horn blast when you are the lord of a Town/Castle and you are entering with maybe some crowd/guards banter "Its the King!" would give a better sense of ownership.
Of course "Less Talking, More Raiding" is immortalized -theres a reason for that ..
