It's always difficult to talk about overall quality when comparing games across all genres and platforms. Therefore, perhaps it's best to assess the innovation and groundbreaking design and creativity; when we do this, we come to the logical conclusion that when it comes to platform exclusives, the PlayStation 3 leads the pack.
We're currently basing this on three exclusive titles: Metal Gear Solid 4: Guns of the Patriots , LittleBigPlanet , and Killzone 2 . Arguments can be me made for or against each one of these, and we certainly appreciate that; in fact, many will argue that Guerilla didn't actually do anything "new" with KZ2. We will disagree, but we won't discount the other side of the debate, because both sides can make valid points. However, when looking at the PlayStation 3 exclusives currently available, it appears they are the titles that are making the strides that seem to be "next-gen." That term is something everyone in the industry has over-used in the past few years, but it may be quite accurate to say that such a term applies more to Sony's platform exclusives than to anything else. The strides designers, story tellers, and engineers have taken with the likes of MGS4, LBP and KZ2 are most impressive, and in our view, currently unparalleled.
Obviously, we've got a long way to go in this generation. And one could easily make a case for Gears of War , which may have revolutionized the third-person shooter. However, GeoW kicked off right around the time the PS3 limped into the generation and many like to say the "combat" didn't begin until that time, when all three consoles were finally on the market together. Counting the last two full years, it seems abundantly clear that PS3 exclusives have pushed the envelope more often. Furthermore, looking down the road, we imagine the likes of God of War III , Uncharted 2: Among Thieves , and Gran Turismo 5 may only reinforce the point, although Naughty Dog's sequel may only be bigger and better than the original; it may not be "groundbreaking." GoWIII and GT5 on the other hand…? Yeah, our expectations are super high. Based on what we have and what we will have, the truly groundbreaking games are on the PS3, and we still have a ways to go.
We're not saying the 360 or PC (or even the Wii) won't ever produce groundbreaking titles; this is more of a current situation analysis. Also, please bear in mind that this isn't an overall quality assessment, either; we're merely focusing on one facet of the titles in question.
