Any day now, the first official Xbox LIVE games from Microsoft, Hexic and Flowerz, will appear in the Windows Phone Marketplace. These games are “real” Xbox LIVE titles in that they have achievements and work with the Xbox LIVE service.
I also noticed yesterday that the Marketplace app display has changed again, with the addition of an AT&T AppCenter. AT&T is apparently testing its online store capabilities and has a (lame) store section and sample app called Test_Journal available. Here’s how the Marketplace app looks now:
As you can see, I still can’t get that pesky Layer app to update. :)
More to the point, this represents one of the ways in which Microsoft’s partners–in this case, the wireless carriers–can customize the Windows Phone experience. They don’t get their own store, but they do get their own section in the broader Windows Phone Marketplace. That seems like the right way to do it.
