Finished Replicant and Automata, What’s next?

I recently just finish Nier Replicant and I’m filled with a void now that it’s over. What should I do next?

I’ve heard things about Drakengard which I’ve heard is tied to Nier as well but evb only talks about Drakengard 3

I’ve heard about some discontinued game I think which is Nier reincarnation

And then I’ve heard about some books and stuff.

Which should I do and if it’s everything, how should I go about it?
