I just don't get why people just automatically assumed that by bundling a Kinect, every developer would automatically add features for it. Unless I missed something from Microsoft saying it was a requirement.
I don't think its an assumption that every developer would automatically add Kinect features. But, instead that there is an incentive that developers can do creative things with Kinect features in their games without end users requiring the purchase of additional equipment to achieve it since everyone already had one.
The biggest issue is that Microsoft's 1st party games didn't/haven't used it effectively.
I think the biggest use for it that I've seen is how Dead Rising 3 used the voice stuff. It heightened tension in the game if you made a noise and the zombies 'heard' you and came after you.
They need to port over Kinect Party from the 360 as soon as they can. That game is fun.
There is an indie game that looks interesting that combines controller use and the Kinect where your body 'reveals' the level, so you have to move and twist around to get through it. That's a neat and creative use...
