As I mentioned in the podcast, I am currently reading up on "The Expanse" and binge-watched the show. The novels are written by two guys out of George R. R. Martin's orbit, and the whole setting (and parts of the story, from my understanding) came out of an RPG they were playing together.
"The Expanse" takes a lot of its cues from ASOIAF. Not only is there a POV-chapter structure, with the individual chapters bearing the as titles the names of the main characters whose POV they're representing. The story also uses a casual violence that's akin to the random death permeating Westeros, creating a "serious" setting in the process. Politics play an important role, and they are largely a deadly destraction from the true danger humanity is facing. There are a lot of difficult decisions to make in morally grey areas, with few people really innocent or irredeemable.
