Some things to consider always when taking on a new world: What are its primary features—spatial, cultural, biological, fantastic, cosmological? What is the world’s ethos (the guiding beliefs or ideals that characterize the world)? What are the precise strategies that are used by its creator to convey the world to us and us to the world? How are our characters connected to the world? And how are we the viewer or reader or player connected to the world?

Can you answer those questions about your story world? What other factors do you take into consideration in your worldbuilding?
