Art isn’t a progression. “Realism” isn’t necessarily a goal.
If capturing some subject in the most naturalistic way possible was the goal of art, there would be no need for paintings after the invention of the camera, and sculpture would be obsolete because of 3d scanning. Art must be something beyond capturing nature, otherwise there would be no reason for humans to do it.
This is genius! A citybuilder as a lovecraft cultist? How has nobody thought of this before?
