I’m on a Mistborn binge at the moment and I absolutely adore the worldbuilding regarding the various past religions of the world. I love series that create rich and interesting belief systems and want to read more.
Examples of what I’m talking about include:
Mistborn by Brandon Sanderson (of course), Paladin’s Grace by T. Kingfisher, and (arguably) Dune by Frank Herbert.
