Game in the Brain

Against all the Gods Is an audiobook I’m currently listening to which is set in a FANTASY setting similar to the late Bronze age Collapse (1200 and 1150 BCE).  Like Hard Scifi – the core skills in running such a game is understanding the framework of society and building the details. 

I like it because it covers the earlier practices due to their material access and climate. That humans can still create sophistication and incredible techniques even with a smaller set of materials. This is a kind of setting I would like to run or play, or write about.
