Gameplay
Kinect
From our hands on time with Kinect at E3, we very quickly discovered how much fun Microsoft's new toy is. At the danger of spoiling what what's written below, it's everything the Wii is only more accurate and without all the dated plastic junk that goes with it. There's an obvious and highly enjoyable magic about controlling the game in thin air and it's the kind of thing that'll wow mums, dads and even grandparents in the comfort of your own front room.
Move
There are two words that will go over and over in your heads as you use the Move and that's "precise" and "exact" or colloquial variations thereof. Because of the controllers in your hand, it doesn't have the magic of Kinect but there's no lag and the handling and proper gameplay is excellence itself. It's everything the Wii just isn't any more.
Wii
The nails are rather in the coffin of the Wii now that, particularly the Move, has arrived. It's reasonably good at executing your will on screen but the cursor has always been a touch laggy and slightly shaky as well. When Nintendo upgrades the system, doubtless the gameplay will improve as well but, right now, it's just a much older console
Conclusions
Sony has been quite open it its criticism of Microsoft and Kinect but rather than take this as saying that one system is better than the other, it's really more of a highlight as to the different market that the two companies are hoping to corner, for better or for worse.
With only a four-year-old console to do battle with, it's a little cruel to include the Wii in this contest. Yes, it was the daddy on the motion controlling front but the Move simply teaches it a lesson in precision, accuracy and gameplay excitement for the while - at least until Nintendo ups its ante, which doubtless it will at some point in the future.
Interestingly, it's Microsoft that seems to have picked up the Wii's mantle rather than Sony, despite, perhaps, the closer connection that the Move system has with Nintendo's.
Pricing is relatively similar across the board but Kinect seems more focused on the fun, family market while Move is aimed at the more hardcore gamers. The precision accuracy and exact control of the latter lends itself to in-depth shooters and action games whereas the magic of the no-hands Microsoft Kinect suits multiplay amusement and a thorough thrill of enjoyment. How they cope with the same third party title, though, might be the real test to wait for.
