@ steam sales... at peak today, there were 105,000 playing CoD:MW2 concurrently. So the total number throughout the day, and the total number of steam sales, would be massive

If this is true, how come VGChartz reported much higher numbers? They reported 12% of total first day sales and at least 6% of first week sales/revenue being for pc. Witch brings the number to about 600k/700k first week.

All MW2 copies count to the stats you mentioned, because the retail version of MW2 is steam-integrated.

I think that is worldwide.

That still doesn't sound logical. MW2 always sales by far the most in America, so with a 170k total it could only have done barely over 100k in America first week, that leaves like 500k-600k to europe. No way a version of MW2 sold 5-6 times more in others than it did in America.

Why not? Traditional PC gaming is bigger in European countries after all.

I think that has to be the case indeed. But that still means this topic is misleading, worldwide the PC version of MW2 probably did atleast 1m+ wich really isn't that bad for a PC game.(i believe crysis did about that number ltd). And it means it still earnt them money.

good i hope it dont sell mw2 is the most overrated game this gen!! the online is poor compared to cod 4, cod 4 will be the best game iw will ever make!!

I don't see how MW2 could've reached 1 million already, although it's possible if you count the steam sales. Truth of the matter is that MW2 declined in sales compared to COD4, which is extremely disappointing and a flop. Infinity Ward could've done so much better, but instead they idiotically spent money in making the terrible IW.NET.

They didn't develop the PC version to "make money", they developed it so that it could sell millions on PC. Call of Duty is still one of the biggest FPS franchises on PC.

Yup.  PC games that push graphics always sell well over a long period (if the game's pretty good too that is).  Consoles are different.  The tech is fixed and you see sales for big titles more in line with big movie releases - huge front loading, particularly in US and parts of Europe.  Day 1 few PC gamers (percentage wise) had PCs worth buying Crysis for and they knew it.  When something like MW2 releases, every PS3/360 owner knows it will run the same.

I'd love to see Steam numbers, as I suspect they are higher than many would suspect.  I'm not claiming there's some huge hidden PC market, there isn't, but Valve have got themselves a hugely profitable market dominance with Steam on PC I think, and with their clever use of sales, etc. lot's of games many wouldn't even have on their radar will still be selling well through the service.
