As someone who listens to the OST of the original NieR and Automata almost every day (and night to fall asleep to). (Drakengard as well for that matter.) To me they are worlds apart. Personally I don't really hear the similarities either in harmonic progression, rythm or orchestration. I might just be a bit too familier with the tracks to be honest, but still. Keiichi Okabe's strength is in his amazing versatility and experimentation (when he has the freedom to do so), combined with Yoko's vision and sometimes very specific/but mostly loose direction. Thanks to this, their duo puts out amazing OSTs that cover a wide range of styles without feeling way too similar, not just what's in Automata.
Even though I don't agree, I can see where you're coming from. A lot of games with the high tech/future aesthetic uses similar intruments in their scores. It does sound familier, like it's a mixture of a lot of tracks I heard before. Personally it reminds me more of the Mirror's Edge OST.
It does sound good, especially for a fetish XCOM game.
