There's both Karma is the type of person you are Fame / Infamy is how a faction reacts to you based on how you act around them.
getting the DLC can make the game significantly easier. Operation anchorage can make you basically start the game with power armor and an ungodly sniper rifle.
in Fallout 3 the NPCs are stiff and dont have any movement animations. their heads turn upside down too wtf. how do i fix?
No, but this game is really rewarding. It's not even really hard per se, you just have to realize that dying isn't a big deal. It's hard in a good way, because every time you die you know it's your own fault. Once you master the game, you can actually beat the whole game as a level 1 character in an hour through sheer skill. Unlike God of War 3 where I keep dying during platforming because the jumping mechanic is awful and combined with the uncontrollable camera, I can't always tell if I am across the gap.
LOL playing Fallout new vegas with the wacky wastelander trait. Owen and Beru are in nipton burned on the east side. i didnt get it buy my wife clued me in that it was a reference to lukes aunt and uncle in star wars.
