okami is an incredible game
game of the year doom eternal
Depending on your mood and time on your hands, Spider-Man PS4 and God Of War is pretty easy to pick up and play some at the time and like somebody else said, wait for the remaster for the original Nier if possible and play it first. ZHD is also a good choice imo
God of War
Then The Last of Us next month before part 2 comes out.
If you haven't played DMC5 already then you should in the future.
