Dishonored or Dark are the first two to come to mind.
I am playing Dishonored now, love it.
I heard Reno - The Menacing Mormon boasting about how good Dark was, but I haven't really heard anything about it outside of his claims that it is 'better than sex' and that he would 'sacrifice my Mother and Father, if it meant I could spend an eternity with such a game'.
For obvious reasons, I have added Reno to my ignored list.
I've heard Dark isn't as good as it could have been but it's still not terrible. Also vampires, which are pretty cool I guess.
Also survival horror games like Penumbra, Outlast, etc if you wanna count that as stealth.
Prototype has stealth elements if I recall correctly, but for the most part it's just slaughtering everything with super powers.
