The Dark Forest Principle

Most of it the Bronze Age part especially so I like the part where they talked about how the trisolarin culture has changed. Yeah I've come to expect the style of this series is that there's really only a couple characters that act as your sort of anchor to the to the story and that he will consistently introduce characters not for the sake of your investment in their character themselves but just to make a point. He also dives a lot into earth psychology and like just humanities psychology in general and just kind of like groupthink.
