Is not that deep dawg.
I can recommend you actual books if you wanna read or when it comes to indie video games with rich story check out Fear and hunger, Blasphemous , Darkest dungeons , Pathologic and the list goes on. ( No Ai included)

If we're talking Goddess Maker proper, not OutGrow, the fan mod of Goddess Maker that uses AI Art assets, then yeah, there's plenty of Berserk-inspirations, though I'm not a big fan of the visual ”vulgar to disgust someone" elements; instead, I like to include the "existential struggle against the ever-omnipotent being elements,” focusing both on a personal will-to-power as well as a will-to-power coming from someone in opposition to the player.
Nevertheless, there is plenty of Kafkaesque nightmare fuel planned.
