Thirding (?) this. The integration of gameplay elements into the story and the story itself are simply amazing. It is similar to Undertale, in that the gameplay is relatively shallow, but is paced perfectly with the story.
I hate fighting games. I especially despise melee action games. I don't love 3rd person perspective. I haven't really played JRPGs.
Nier:Automata jumped at the top of my list and kept getting better. Even my (non-gaming) wife watched me playing because she was curious and the art and story were fantastic.
A unique experience that is difficult to put into a review. FWIW, my other favourites are Mass Effect, Deus Ex, lots of Sierra & Lucasarts point & click games, etc.
Story telling and surprises (and style) in NieR:Automata were just top notch.
