After watching the Day Z behind the scenes I've just been thinking about motion capture which has become a proxy for a lot of other game development activities.
For the past 10 years we have been capturing live action actors motion and translating their actions into games. You know, a black one piece with ping pong balls attached to every joint.
So we should have a shared library of human motion.. after 1000's of hours of motion capture for 100's of games we should be able to represent the majority of human motion from crouching to jumping to punching.
My general feeling is that game developers are being asked to re-invent the wheel instead of creating unique experiences.
