You tried this with ranged weapons yet? i'd love to see you do this with crossbows, seeing as it would be cool seeing you with your hat, and standing leaned slightly forward, and shooting a crossbow xD
However Warband needs this more than 1.011 especially in complicated mounted combat.
(How to play perfectly on this mod/expansion/hack or whatever it is):
1)Turn Camera FPS.
2)Put on 3D glasses.
Hah, that's pretty neat, if only the kinect didn't had that horrid latency to it.
I don't have a 360, but I've been entertaining the idea of getting a kinect just for messing with all the crazy stuff people are coming up with it for the pc, your video only made me consider it even more.
