Being engrossed in your created world and what happens on it and because of it makes for a wonderful distraction from the ever grim news bulllletins etc.
However, your created world should not be perfect. No world is (well not in this dimension). There should be characters who dislike the situation they are in and are looking to escape it. Can they do so? What are the drawbacks of your world? Can one aspect of it appeal to certain characters yet seem like a burden to others?
How does your world deal with the awkward ones (like my Eileen)?
Answering questions like this will help you flesh out your created world nore.
