More often than not, many times it's worth returning to places you've already covered as things change. NPCs frequently will have dialog recognizing quests you've progressed and solved - oftentimes even giving a little extra experience beyond the experience you get completing the quest itself. It is a nice touch and makes their games and endless search for Easter Eggs.
