This list is great.
I can't understand, however, how anyone could claim they "greatly prefer" Sony's list.
I doubt anyone has played WKC, and Gran Turismo is a demo.
You've got, from that list only, Killzone 2, Uncharted, and LBP that are really worth bragging about. Look at both of THOSE actual lists one more time, ffs.
Now, if you add MGS4, Sony is starting to show a little something, but THAT game is not on THAT list. Without it, I think the list provided for MS is clearly superior imo. Mass Effect being included, as it is, as well as both Gears games, Crackdown, Forza 2, Fable 2, and Halo 3. All of those are pretty fantastic games this gen.
So, even if you argue that the MS list PROVIDED HERE isn't clearly superior, I don't understand how you can claim anything more than a marginal preference to the PS3 list. Without MGS4, the PS3's exclusive lineup SO FAR this gen is neutered. It's just about half the reason to even own a PS3, or at least it was until LBP came out. If you prefer the PS3 list without it, then you must be apeshit over the console, when you include it in a list like that.
I think some of you might be seeing these Microsoft exclusives as bullet points, or maybe you've never actually played them. Mass Effect is GREAT. Crackdown is GREAT. Gears 1 and 2, are like two Killzone 2's. You must understand, the 360's lineup rocks. Some of the best games don't appear on the PS3. It's fine to love the PS3 and its great library, but don't degrade or marginalize Microsoft's games. They have been rocking this generation for years, and indeed have defined it for many gamers. What is this gen, without Gears of War? Much worse, with an identity crisis.
