Definitely Gravity Rush 2 for me. Super unique traversal mechanics and combat. Nothing else like it.
2nd would be The Evil Within 2, then maybe Horizon Zero Dawn which is more just a decent game I played.
I want to add Nioh and Nier but the grindy RPG nature of them prevented me from playing. Nier has less and I might consider it later when it goes down in price.
I'd definitely give them GOTY for game mechanics though.
