so there is no concrete evidence that CS:S sold anywhere close to 10 millions... also, the concurrent players would include HL2 owners.
Even if CSS sells on Steam for 50,000 copies per month in the last 5 years, that's 3 millions. In addition to the 2.9 million copies in the retail, it's still 4.1 million away from 10 millions. Maybe my estimate is too low but I would like to know how you think CSS or even CS sold/will sell 10 million copies as stand alone games.
MikeB predicts that the PS3 will sell about 140 million units by the end of 2016 and triple the amount of 360s in the long run.
