I think I'd like to see what people would do in their leisure time or domestic work . You see so many stories about travel and war, but you rarely see people interact outside of that. And if you do, it's usually not made unique for a setting that isn't Earth.

What cutlery do they use? What does a morning routine look like? In a world where fire magic is commonplace, how do they cook? How would those things evolve over centuries?

Fantasy especially feels stagnant for this, but I think sci-fi is guilty of this too. Are there things in specific works where an innocuous detail made you wonder more about how a setting worked?
