Can you elaborate how the themes in this game map onto themes in Brothers Karamazov? I tried doing that myself, based on plot synopsis in Wikipedia, but was not able to.
Not to mention that just equivalence of narrative content does not mean anything in terms of work of art's quality - i.e. one could write the most wretched version of Brothers Karamazov, with technically the same content, but just no substance... The true value of work of art reveals itself in how deep it is - i.e. how much it can deliver to its reader (in terms of richness of characters, jumping points for philosophical thought etc.). BK were studied for over a century now, with countless articles and PhD theses from different angles written about it - a true testament to its richness. One can wonder how deeply "Nier Automata" will be studied.
