This feels like a first or a very rare instance, a multiplatform game getting the same scores on both platforms? It looks like Infinity Ward really knows how to make a game. The link below will be for the PS3 review, but that really doesn't matter as the reviews for the PS3 and 360 are the exact same. I hope everybody enjoys it if they get it.

As for myself, I'm still locked in the PC vs PS3 decision. It'd probably run the best on the PS3 (The demo ran decently, but not entirely smooth. . I need a new video card), but the PC and mouse is what I prefer when it comes to FPS games.
*edit* It looks like IGN had scored the PS3 and 360 versions the same as well.
