Watching how the new Mass Effect game is at it again with bad animations, somehow as a reviewer talks about how you interact with others in the game, it had me thinking, so this is a free idea for all you terrible game devs:
"dialogue wheel" modifier = modifies the reaction of your group members, you get angry, they feel angry, you are calm, they are calm (unless someone has a quirk that makes them easily upset, for example)
And, as for the npc's you are interacting with, if you are angry to them, they should perhaps get angry at you in return.
