The feral ghoul sounds exactly like the Draugr...

don't think I didn't notice.

Dog and Bear Sounds copied too (lazy-thesda)

Well, let's be honest, how much variation do you need for bears and dogs and withered wrinkly things that wanna wreck your face?

Personally I like the soundbite from F3 better when it came to the ghouls, made them creepy sounding and threatening.

The draugr also I didn't like much to begin with, zombies from Oblivion with their squishy walking and moaning were creepy and just plain gross.

The feral ghouls do sound cool on headphones, up close & personal.
