I just noticed last year's E3 gameplay video was insanely good, even better than the final copy.
The way enemies exclaim and talk to one another across rooms, all their animations and how the camera closes in when strangling them or fighting them using hand to hand combat is just fantastic and much better overall.

For example, in the video above, when he went in to melee a guy carrying a shotgun, the guy got surprised and his shotgun accidentally fired. On top of that, the guy YELLED "he's in here" to his buddies. Never had that happen to me when I punched people!
How come the final game doesnt feel as good as this?
