This game is Excellent, capital E - Excellent. Make no mistakes though: this is a first person shooter where you must not shoot anyone because everyone is stronger than you and you get chewed up in a face to face  battle: the emphasis is on stealth and invisibility and it's the first time  that I have seen anything like this. It's nice to know that there's still  room for originality in the gaming world.  In this game you are a thief and  (of course) you have to steal stuff. That's it. That's all you have to do.  It's how you have to do it that is gut wrenching: you have to sneak  undetected in shadows and move slowly. It's great that there's a  'stealth-o-meter' on the bottom of the screen: it's a gauge that tells you  how visible and noisy you are at the time. Helps a lot!  I have to give  credit to the designers and developers: they thought this through a lot and  came out with an incredible game play. I just bought this game and I am  amazed at how good it looks in spite of the fact that it is an 'old' game.  The models (soldiers and monsters) move in a very realistic way. On top of  that I am very surprised at the dialogs and voices. I kinda feel guilty to  do it but I really enjoy myself just sitting in a dark corner and listening  to a guard only a few steps away complaining that he is starving or that  his bosses are incompetent or just mumbling senslessly to himself. It also  has a good story line and some levels are really creepy and very well  designed. This game is a must-have if you like a change of pace from the  various Quakes and  Unreals...
