Would be nice with a bit of updated NPC dialogue depending on what new events are going on in the world. But beyond that I'm not expecting much else to change when I re-visit a town. It might also depend a bit on how much time there's been between the two visits. The less time it has been since the last visit, the less I expect to change. But if for example, the party returns to town after an ingame year or something, it would be nice to see a bit more than just updated NPC dialogue.
