please note that i'm talking about FPS games with a decent SP experience (at least 10 hours on easy, nothing like that CoD BS where you can finish it in 6 hours). i'm not into multiplayer or exploration. i'm already finishing up crysis 2, and i've already finished deus ex (but that's an RPG for me, not a FPS). also, it would be really nice if the game were available on Steam.
