Game developer Bethesda Game Studios suggested that Microsoft should open up Natal to enable developers to create non-game related applications for the motion sensor:
“Seeing Natal in action, I was totally blown away by it. It seems wasted on games, really. Microsoft should open the Natal API up, like Apple does with the iPhone/iPad. Let anyone make a Natal ‘app’. I bet someone makes a killer app that has nothing to do with gaming,” said Ashley Cheng, the production director at Bethesda Game Studios, in a blog post.
So far Microsoft has not announced any plans to open up Natal or Xbox 360 APIs to independent developers due to the fact that it can neither control the quality of applications, nor receive royalties from such developers nor control its consoles. By contrast, Apple controls everything that is iPhone/iPod/iPad-related: it sells applications designed by third-parties itself, it ensures that applications comply with Apple’s policies, it does not allow installation of anything it does not sell onto the devices, it does control usage of its products.
