I like how the Disco Elysium writers did historical materialism in the world building. There's the central conflict over the strike that sets the stage for the murder and Harry's story, then you have the revolution/civil war and the coalition airships hovering in the background enforcing the counter-revolutionary order. So class struggle is at the root of everything else in that world. It's like you can decide you want to tell a story rooted in a particular class conflict, then the dialectics of the class conflict help you elaborate the rest of the world, it's an interesting approach.
