This is the first time I've seen these HL2 movies. I was more impressed by the AI on one particular movie where Gordon pushed the table infront of the door so the soldier started shooting thru the window and then blew the door open. I haven't read anywhere about the physics being totally scripted or not but to me a lot of it looked scripted.
A couple things that rubbed me the wrong way was the fact in one movie Gordon knocked the monitor off just by walking into it, the monitor went flying off and spinning, damn that Gordon must have some body strength
Hitting enemies still doesn't seem improved from the original, the monster was hit as soon as the crowbar began to swing.
Hey, I'll still be getting it, they're minor issues only, but the more hyped the game is, the more I seem to notice these indescripencies.
