I like your profile pic.

In moderation, I think it would be excellent. Visible bullet wounds and broken limbs, etc., most definitely. But no gibbing or whatever. That's just silly and ends up detracting from the realism. For instance, in IV, there were some spots on a character which, should they be hit by a bullet, would spurt blood for a few seconds. I remember seeing Niko's chest and back full of bullet holes after a gun battle with cops.
