When reading Thuderhead, I felt like it didn't have the same charm as scythe. The whole reason I loved scythe so much was due to learning about this new world and it's concepts. So the worldbuilding pretty much. 

I felt like Thunderhead had more of a forcus on the 'plot' and the charter development. But I use word 'plot' super lightly because it felt like Thunderhead didn't really have a plot to move the story forward. Or a reason why XYZ was happening or why I should care.
