The dread starts at the very beginning, simmering in your gut, and it never gets better ever - hour upon hour. You know immediately that you are engaged in something like evil, if not evil itself, but our appetites as players demand that we seek objectives and conquer them - and the game scourges us for this dereliction of conscience. The technology at work often obscured the game itself, but the emotional wavelength has resounded years after the fact. At this late hour, I can recall no camera foibles or performance valleys. All I can recall now is the black bargain, and concentric waves of anguish.
And that's exactly why people like me point to that game as an example of how games can become art.
