Fallout 3 is overall an amazing game the graphics are good the action is good and the V.A.T.S aiming system is top notch.
The game starts out with you as a newborn infant in Vault 101. From there you play through key moments of your childhood until one day your Dad leaves the Vault and now the overseer is trying to kill you. You also leave the Vault and find youself in the wasteland of Washington D.C. After that you are free to go about where ever you want exploreing anything and doing any quests you want to. I give this game a 10/10 and say it is a must buy.
