I second this. Some ambient chatter by NPCs would be interesting. No new NPCs would need to be added to this. Just let some store clerk spoof serving a customer now and then, let rychek scrub a glass or polish some bottle. Whatever. I think it could make hanging around in a place, waiting for some players to join, a little bit more interesting (and gives your character something to react to, like emoting to watch rychek while listening to a boring conversation)
Who knows. I think it could give the game a lot more depth and make the various locations feel alive.
I also would support making the little messages that get added to descriptions while walking the streets, for instance someone being dragged into an alley, fire at random intervals as emotes, or spoofing. That way all players would see the same message and it wouldn't feel like it's just the room description. Again, making the game feel more dynamic.
