First-Person Games With Stealth Focus (Thief-likes)?

Hello!

I've recently gotten the itch to sneak around again. I've played Dishonored and Thief (2014) and enjoyed them a lot. I've also played a lot of sneaky Skyrim.

I was able to get the original three Thief games for like $1.00 on a Steam sale, and I've got Dishonored 2 and Death of the Outsider on my wishlist. I'm also considering Far Cry and Fallout, but I'd prefer games with tighter stealth mechanics.

So, please recommend first-person games that focus heavily on stealth or allow me to play stealthily most of the time.

Thanks!
