Valve – developers of games Half-Life, Counter-Strike and Team Fortress, among others – have recently updated their game statistics page. They added some very nifty gameplay statistics for Half-Life:Episode 2 and, more recently, they’ve also started a new edition of their player hardware survey which automatically gathers hardware and software data from Steam users through the globe.
The big news is that this version of the survey also detects whether the user has some specific applications installed – on my case, it successfully detected FireFox, OpenOffice, and Zone Alarm. Data from those specific results are not listed on the survey results page yet, though. Personally, being both a FireFox and an OpenOffice zealot, I was pretty happy to see something like this popping up there.
Finally, Tom at The Steam Review has some additional discussion about it.
Update: awesomely-named RockPaperShotgun.com also has an analysis of some of the preliminary results of the new survey.
