Fallout 3 takes a bit of Patience. I for one love Fallout 3 more then New Vegas, because the story was much easier to follow. For one, if you go wondering into the wastland, your going to find something to kill you. If you shoot at everything, its going to shoot/attack back. Honestly, just play it right. I know your probably talking about the deathclaw close to the starting point, just don't go there next time. Seriously, quit your whining and enjoy the game.
