Half Life 2 Episode 1 Playing Stats

Valve has been collecting data of how people have been playing the game. You can see the results Here.

The results are as you would probably expect. More deaths on higher difficulty levels further into the game. And there is a gradual decline of how far people played into the game, but this includes all games not just the first time through. And it seems that the average length of time to complete the game is five hours. The only slightly interesting thing is that most of the people that stopped playing their games, stopped playing them when they hit the carpark section with the antlions.
