Easily the weakest point for me is the difficulty I had trying to share the main campaign with friends. At least if people are close to the dialogue-giving npc, they should get to see what is said. If someone is off doing their own thing, that is fine, but please allow people that want to experience the prompts to do so within a certain radius. Make the first person to approach the npc in charge of prompt choices, but let anyone else in the party see what is said.
