Please keep this as spoiler-free as possible, I (and others stumbling over this question since I haven't found answers for it either) might not be in the x-th playthrough yet – still a bit to go, so asking in advance.
Since the remaster of NieR: Replicant/Gestalt received a new ending to tie more connections to NieR: Automata I'm wondering when I should leave the "first" game be for now and experience the second game for the first time.
Does the new ending spoil anything I shouldn't know starting into Automata or is it really just to bridge some questions or create new references/callbacks in the second game?
I know possible answers might be subjective, so please try to consider an as objective standpoint as possible. I don't mind vague answers, if they avoid spoilers.
