One of the best things about Skyrim is that you can play the game however you want, so it's never boring watching your friends because they most likely will play the game much differently than you. From a take-no-shit mage that incinerates everyone in its path (even hot babes), to an invisible thief that steals everything including the shirt off your back–it's your choice.
YouTube user WestSideLuigi has decided to play Skyrim as a pacifist; at level 9, he has yet to slay anyone or anything.
Personally, I have way too much rage and inner demons to be able to even attempt that feat, but props to the guy! I wonder how long he can last since the game is literally infinite. I also wonder if he will be able to finish the main story; I'm not far into that quest-line, but has it required anyone to kill (eg. the final battle)?
Anyway, watch Felix the cat confuse and calm his enemies above.
