Horizon: Zero Dawn would be a big one, it's a big open world action game that has you fighting robot dinosaurs in what is technically a post-apocalyptic world.
Bloodborne is a must, unless you don't like the Dark Souls games. I think this one is my favorite of them for sure.
Nioh is similar, but has much more depth to it's gameplay with stuff familiar to Onimusha and Ninja Gaiden (More modern ones).
Uncharted 4 is good for the third person shooter adventure angle and if you played the previous ones, it's good to get into.
To me, those are kinda some of the biggest. Some light recommends would be Last Guardian, Yakuza 0, Persona 5, Nier: Automata, and Infamous: Second Son.
Not too mention what is coming in the future with God of War, Last of Us 2, Days Gone, and others.
