I don't own an Xbox and my PC is ancient. My wife just gave me a PS3, so the choice was easy. I have only played the first few levels and I love this game. The story, the atmosphere, the dolby sound effects all combine to make a truly landmark game. I even like how (at least on the easy level) you can get hints and view maps and read about the various items in the game. A nice touch is the diary system to get more of the back story and info about goals. This is an awesome game for any platform!
