This raises questions, of course, about how Valve use the data they obtain through Steam, especially in light of yet another spyware controversy. It was no less a luminary than Monkeyfilter itself which played host to suggestions that the Steam system treated customers like criminals. Is it now placing them under surveilance? Will the next logical step be dawn raids on particularly inept n00bs? That aside, there is some interesting info in here. Apparently completion rates are lowered by people who restart without getting through the credits sequence, but have only 47% of players really persevered through the admittedly highly repetitive tour-guiding episode of "Exit 17"? Unfortunately, it did not collect some of the statistics I want to read. Like how many times are players zooming in on Alyx Vance's face while singing "To Love Somebody" by the Bee Gees? How many times does the average player hit a downed drophip with a crowbar to make its limbs jiggle before it stops being cool? How loud did microphones record cries of "No, Barney, let's not do that. Let's all run across in a single heavily-armed group, before the Combine can bring in reinforcements. You multitool". How many times has a zombie been set aflame just to try to work out what it's screaming? How much treacherous speculation has been entertained as to whether Roberts Culp and Guillaume will stay hale and hearty long enough to record voices for all three episodes? All these and more... So, how far up the obsession curve are you (I'm a bit disturbed to find myself not just in the upper quartile but the upper sesqupidile, or something to that effect)? What statistics would you like to see measured? And, most importantly, are you one of the crazy people playing it with DirectX 7?
