I agree. However, it has been stated in multiple places multiple times that it's the retailers themselves (Steam, Impulse, etc.) who refuse to release their sales data. So lack of accurate digital sales reporting has a lot more to do with that, and a lot less to do with tinfoil cap conspiracies about MS and Sony buying up the truth.

One point on that MW2 sales figure. According to Steam's stats page, the peak population of MW2's multiplayer in the last 24 hours is well over 100,000.
So your telling me that half of all the people that bought the PC version of MW2 were playing multiplayer at once? Really?
@Navagon: I think you misunderstood my point. The PC version of MW2 shouldn't be getting Xbox Live errors, since there was no part of Microsoft's Live service was implemented in the PC version: it's all Steamworks and IWnet. It's like it's coming up with a PSN error: a sure sign of a sloppy port.

That stats page is quite interesting, thanks for mentioning it.
I also agree, it seems the PC-version of MW2 has some really solid numbers, despite all the boycotts and noise, and it is is fairly obvious that the investment in that version was worthwhile.
This is important to be aware of - when talking about sales numbers, it's not about which format has the highest/lowest numbers. It's simply about profit. It doesn't matter if the PC version sells less than, say, the 360-version, what matters is if it sells enough to be profitable on its own. If it is, it is a good investment.
I have absolutely no doubt that Alan Wake on the PC would be a good investment for Microsoft and Remedy. It won't sell more than the console version, but will sell enough to make money - and the development costs of this game are obviously quite high, so every bit of profit counts.
From a financial point of view, it would therefore make a lot of sense for Microsoft to port the game to the PC. The only reason they don't do it is that they want to promote the Xbox 360 and "force" PC-owners to "upgrade" to that platform.

My point is that multiplatform games start off like this. Multiplatform games are designed for consoles these days. Allot of PC ports are just the X-Box 360 version with variably reliable support for some graphics options and mouse/keyboard support. Several don't even have text chat.
Overall I had fun with KotOR when I first played it. It's just my opinions of it soured with time. What I was criticizing about it was all the things that make it a console game and inferior to Bioware's pre-NWN PC games. They add up. If you consider the drop from five possible NPC allies to two or being forced to take along party members you didn't like, and the choices you make in several instances all leading to the exact same reaction to be a minor interface issue... well I'm not sure what to say.

My point in posting the sales figures was to illustrate that game companies just don't care about PC gaming. The people who run companies like EA, Ubisoft, Activision, they aren't gamers. They are businessmen, and their goal isn't to make sure that you are happy, it is to make money. Pure and simple.
Let's look at Modern Warfare 2's sales figures again. The PS3 and Xbox 360 dominated sales, while the PC, while still an impressive number on it's own, shows them that their focus point is on the consoles. They don't care about the PC gamers complaints about leaning, or dedicated servers, since implementing those would have taken away from the development of the console versions, or tied up extra resources making another version that would not have sold as well.
From a business standpoint, the PC version had lackluster sales, while the console versions flourished. PC exclusives are pretty much gone. What I predict PC gamers will see in the future is games like MW2, console ports that are mere shadows of what they could have been on PC. Sure, there will be PC exclusives, but will they be enough for people to shell out the cash to buy a computer capable of running it smoothly? Probably not. Yes, there are companies that care about PC gaming first and foremost, but they are a dying breed.
It was impossible to say PC gaming was dead around 2000, since PC's still dominated the market in terms of power and graphics. But that line is blurring continually with every new generation of console.
Don't get me wrong, I loved PC gaming, but nowadays, all I find myself playing are games from 2007 and back.

This is to add some gas to Wraith's statements... I have been a PC gamer since the late 90's... never own a current gen console....
Now since i have a ps3, i have to say im honestly 100% happy with it, and it plays games that may look like glowing aliased crap but its comparable to PC... Ease of use, no DRM and the ability to play what i want without dealing with spyware, ring 0 software makes me again 100% sure i will upgrade to the nex gen consoles, and never look at a PC again...
Duke Nukem Forever, Diablo 3 and Grim Dawn are the only things im waiting for.. that and all future GoG releases... i have no need to upgrade again since i have my PS3.

Until the PS4 is released, and you have to hope they enabled backwards comparability with your PS3 games and downloads. And even then, there's no guarantee the PSN will remain switched on for the PS3 forever.
Which is one of the failings of consoles and one of the strengths of (most) PC games: the online modes last as long as someone is running a dedicated server for the PC game, while the console's online modes get nuked whenever the publisher (or manufacturer of the console) feels like it.

the only content i download are the free ones, and Im going to upgrade to a TB hard drive in my console... from there i can just clone the drive every few years to keep it working and I already have a ghost of my current on a backup.
but your right, thankfully i dont ever buy DLC, if i want it i get the GOTY edition or i live without. on the computer i'll grab GOTY edition.

Close, but there's a bit more nuance to it. One must not only consider whether or not an investment is profitable, but whether that money could have resulted in a much better ROI if used for something else. Basically, while real costs and profits obviously need to be looked at, opportunity cost can't be neglected either.
