S'mon said:I just don't find 'you take 10 damage' very horrific - "you take a severe wound to your right arm, crippling your hand..." would seem better for a physical horror game like AFMBE.
From that perspective, yes, a more detailed damage system might be interesting...
But if the Director/Game Master/Whatever it's called in AFMBE has to slow down the action during combat to figure out where the PC got hit, then you can lose a bit of the feeling of a mass of zombies swarming over you.
Again, fast and loose combat helps the cinematic feel that's almost necessary to get PCs worried about all the zombies that are everywhere, but I admit, that's just my opinion.
