I can't remember for the life of me who stated as such maybe Todd? but it WAS said that others would be able to use the language/shouts as well as the PC which to me is slightly worrying because it takes away some of that (IM SPECIAL) feeling being the dovahkiin brings with it if everyone one else can do what i can do. i understand the greybeards being able to do it two. but think anyone other then them is to much i mean hell a dragon born hasn't been seen/heard of for over 200 years so why now would there suddenly be individuals/groups of people with the same abilites your thoughts would you like to run in to rare NPC's with the same abilities as you maybe even different one's to you? or do you want to feel unique like me lol.
P.S im sure BETHESDA will do everything perfectly well i was just interested in others opinions on the subject please excuse my spelling grammar and punctuation
