I'm fine with it the way it is. Some games go way overboard with gore to the point of ridiculousness. I wish all violent games had a dismemberment/gore/blood option to turn on or off. That way when someone like me who is 17 is playing around parents I can switch it off, but otherwise maybe go for a bit more realism.
I'm a bloddy decapitator now and the game doesn't keep track of how many heads I chopped off? Damn! Who forgot to add that to the Combat Stats??? Cut his head off!!!
