I like the Kinect and the potential it has. However the input lag in even the most optimized game will never be better than 60ms. Not good for fighting games. The Kinect just can't keep up with what the player is trying to do..
this is a VERY bad example... two girls that had no interest in being there playing a fighting game?? seriously.. thats like taking a teenager and having a virtual clean your room game/.... not going to be into it too much..
Anyways... I do not expect much for the kinect when it comes to full action games.... I want it for the TV control and minor game controls.... and some slower motion games... like Golf or bowling...
I don't like the thought of any game that will make me jump about, I'm just too lazy for all that ;) but I don't think we can/should judge Kinect on one video.
As I always say, I will reserve judgement untill I've actually tried it but heard some promising things from the folks at IGN yesterday after they got to try it out ( Not a particular game but more how Kinect performs ) so something positive from people that
have .. "Actually tried it" ..
