Very creative, but a very hard difficulty keeps it from greatness.
The best part of the game is how interactive everything is. Everything you do from eating to drinking to punching to barfing...yes, barfing, is all in first person, like Half-Life.
The main issue many will have with this game is the difficulty. I would only recommend this game to people who have the patience to just chill and keep trying the same part again and again. THIS GAME IS NOT FOR THE EASILY FRUSTRATED!
The bottom line is, if you have any interest in this game, go get it used, because now it costs about 2 to 5 bucks, and I will guarantee that you will get your money's worth.
