This is the kind of game that sets a new standard for innovation in gameplay. Thief has a great plot, and very original gameplay. You have to think like a thief in this game to have any chance of surviving. Your  supply of weapons is definitely NOT for head on confrontations. There is  something very satisfying about sneaking up on someone and simply knocking  them over the head with your blackjack. Who would think that not  splattering someone all over a wall(like every other FPS out there)would be  so fun? But it is. The only real flaws of this game is the AI and some of  the enemies that you have to face. First, the AI is fine most of the time,  but can be very quirky at times, such as not noticing you when you are  making enough noise to annoy a jackhammer operator or noticing you when you  are silent and still in complete darkness. The other flaw is that in a few  levels you have to deal with creatures that can see you in the dark and  also can't be knocked out. This is annoying because the greatness of this  game comes from sneaking around. This seems to be a common complaint and  has been addressed in the sequel. Despite these flaws, this is one of the  best overall games for the PC on the market today.
