You know, when Rose commented on my character after she saw me blowing Gunnar out in the open, it got me thinking... What if the NPCs can comment their opinions to you about other NPCs (in short gossiping) with RNG based responses as well as even comment on your relationship to said NPC? Similar to how Harold talks about NPCs around Barshade but this one should be inconsequential that doesn't affect their likes or dislikes to you.
This is similar to the Dragon Age series where you ask your party members what they think of your other party members.
Like for example, all NPCs would have a dialogue branch that starts with either one of these "Let's talk about..." or "What do you think about..." or "Can you tell me something about..." And after clicking that line, it would give you names of the people in the area.
Like... let's have Logan as an example. After you click on the dialogue topic above, you'd pick from a list of names in Bareshade. And let's say I pick Gunnar. So Logan would offer a short dialogue about his opinion on the guard, like, "I don't know why you like that sleazy bastard so much." or "If that bastard offers you up in the bar again, I swear I'll stick his sword up his ass", etc. And since this would be an RNG based lines, if you click on the Gunnar again, Logan would have another opinion on him. Maybe a max 3 or 5 lines of that would be enough.
Just a thought. It would give a sense of interconnectivity between NPCs since we rarely see them interact with each other outside certain events. Also it would be amazing if the opinions would change depending on the story progression. Like if you chose Bottom Logan in the story and you ask Bernard what he thinks of Bottom Logan he'll be like, "I've noticed that Logan's been... friendly with the men around lately." or something like that.
