I'm actually very surprised that EA never put the animations in for say, when a guy gets shot in the hand, groin, leg, etc like Rare did for GE and extended in PD. That was so cool. Probably the only game to be taking that to the next level will be Resident Evil 4.
The animations for the baddies in Nightfire were excellent, and were quite realistic, but never really realistic in that they didn't react well to gun shots to their arms or anything. You could shoot a guy ONLY in the leg and he would still die. I know that this happened in GE, but for a newer title, say, lets see them make it so that they will only die if it was a head shot or of body shot. You wouldn't die from a leg shot unless you were left there for a long time.
