It really was the coolest thing when you escaped the final test chamber and found yourself alone in the abandoned facility; the music just stops. Up until that point you knew something was wrong but not quite what. The lack of scientists in the observation windows, the creepy graffiti in the alcoves stating "THE CAKE IS A LIE" next to a mountain of broken security cameras and the disturbing fits the robot would get into on occasion. The game was a great example of the "show don't tell" style of story telling. Also lets be honest, the whole cake thing in Portal was pretty funny. It was just the people burning the joke into the ground and snorting the ashes that ruined it.
