What are some challenging games for PS4? (other than Bloodborne)

Obviously Bloodborne was the first thing I bought for the console, and I've already played the other Souls games too.

Persona 5 is pretty good on Hard, plenty of moments where it kicks your ass.

What are some other challenging PS4 games?

Edit: SINGLE PLAYER, forgot to put that in the title. I'm never paying for PS+ and have zero interest in F2P games.
