Red Dead Redemption 2 has a mind-blowing camp system. There other characters go about their tasks, talk together (both one-on-one and in groups)
Mass Effect 3 had a little bit of this, where you could find some companions together playing poker, or just chatting in the Mess, or drinking at the bar, and you could go up and have a conversation, but you could just as easily stand there and listen to them chat. It gave them more life to see them interract with each other in that way. Would LOVE to see even a small part of this in BG3 at camp. Even if it was just some of the chatter you hear while walking around, but hear them talking together in camp, like Lae'zel and Gale about battling prowess, etc.
