Alright, I will admit. I play MW2 and WaW. In fact, my level in MW2 and WaW are about equal. I play MW2's multiplayer for fun and because I want that AK, dammit! I play WaW's singleplayer because I like the WW2 setting, and it's always fun burning some Germans in the morning.
Now, what I want to know is, why didn't IW capitalize on Treyarch's gore system? Right now, we get a splotch of blood on the wall when a guy gets killed with a HEADSHOT. A headshot, especially coming from a Barret 50. cal, is going to do a hell of a lot more than just throw blood on the wall in a neat little splotch. IMO, when you shoot a guy with a shotgun at close range, you should be seeing some blood flying and meat chunks/arms falling out/off. I'm pretty sure the weapons of today are more powerful than the weapons of WW2, in terms of stopping power.
Let me know if you agree with me.
