Honestly the parts of world building that always intrigues me is the daily life of people. Sometimes the most mundane daily activity can be very telling of the world and characters.

Anime does this so damn well that Disney (do they even make cartoons anymore) and other animation studios don’t get into. Characters cooking, cleaning, getting dressed or even just lounging around on a hot day. They feel like more believable characters because of the nuances of humanity that they reveal through those mundane moments.
