In a sense you are right. It is MS exlclusive, but that doesn't mean anything past the ability to beef up your fanboy list of exclusives, unless of course all you want is MS to get your money (when they don't always on PC).
Look at the top the screen and you will see PC as it's own section. Even if you go to Metacritic it will say: "other platforms: PC ..."
IGN takes VgChartz and Metacritic to the next level when they don't include each companies sub-platform in one branch. They specify between each platform. And guess what they include the PC. So what that it does other things too, it doesn't mean that you can discount it's gaming attributes. There is an entire market built upon GAMING PC's.
As for handheld games ( or in the case of Sony PS3 vs. PS2) such as the distinction between MLB:09 the Show on PS3 and PSP, there should be an asterisk. This is because when the quality of the game changes drastically the relevence of the game being multiplatform doesn't really mean anything. Your comparing a gala apple to a pink lady apple. They are still apples, but very different apples. The same goes for the games.
As some other guy was saying about console exclusive, that too is true. But the main purpose of adding the word 'console' is to fight a fanboy war between the 360 and PS3 (but it's fun and entertaining, it's understandable why it is that way). It is a word that essentially is inclusive to the 360 and PS3.
On a whole it is moot because you are excluding other platforms. Excluding other gamers. To determine what gaming decision is best for a potential gamer you should start by including everything, AND THEN taking pieces away. That way a gamer can make the most educated decision.
Start big, then narrow it down.
