Dunno how many that already have said it but Thief: The Dark Project is the best fps stealth game ever made.

It's sad Looking Glass Studios ended up the way it did after the second game
think they could have kept on going making some more nice games if it wasn't for that they went out of buisness, 2002 I think was the year.... Thief a classic serie and a classic game, and it will always be
