One of the best games I have ever played. Enough has been said about all the games this does well, but I think the biggest thing for me was just how much the game ... respects your intelligence as a player. I constantly felt like I was doing insanely out of the box crazy stuff only to realize that's what's actually needed to solve the puzzle and advance. The story comes together beautifully and the ending sequence has got to be one of the best in any game, ever. Would literally recommend to anyone (except people who get motion sick from FPS games!)
