I just stumbled upon this web site: http://dev.zr40.nl/steam/
The guy who created it made an algorithm that systematically scans every single public Steam Community profile for achievement stats. It takes approximately one month for the system to cover all accounts, based on the stats it shows for the number it covers per day.
Further interesting because Valve just revealed that there are 25 million active accounts, yet only 10 million with Steam Community profiles. This is further reduced when you consider that not every one of the 10 million Steam Community profiles are public.
So, of the 25 million accounts, how many have public Community profiles? 5 million? 9 million?
Either way, look at some of the numbers here: http://dev.zr40.nl/steam/games
Again, the numbers shown only cover public Steam Community profiles, and only 10 million of the 25 million active Steam users have Steam Community accounts to begin with (public or private)
Team Fortress 2 1,740,658
Half-Life 2: Episode Two 1,255,624
Portal Portal 1,247,849
Left 4 Dead 1,216,644
Call of Duty: Modern Warfare 2 1,023,973
Day of Defeat: Source Day of Defeat: Source 2,500,776
Left 4 Dead 2 673,940
So based on this web site, there are more than 1 million public Steam Community profiles with Modern Warfare 2 achievements registered.
Does this mean that there are multiple millions of people who own Modern Warfare 2 on PC?
Could this mean there are 7+ million Team Fortress 2 owners? 3-4 million Left 4 Dead 2 owners?
Even if this represented comprehensive numbers, not limited to public Steam Community profiles, I gotta say it's pretty impressive based on what people might expect for PC game sales.
What does GAF think?
