Fallout 3 takes place in a post-apocalyptic United States in the year 2277. The player character is a member of Vault 101, a fallout shelter serving Washington, D.C. The player character lives with his/her widower father until, one day, the player wakes up finding that the father has left the vault and ventured into the wasteland for unknown reasons. The vault overseer becomes suspicious that the player had something to do with the father's disappearance, and the character decides to go out into the Capital Wasteland in search of him. Along the way, the player will encounter organizations seen in the previous games, including the Brotherhood of Steel, a group of technology-coveting survivors, and the Enclave, the elitist and genocidal remnant of the U.S. government.
Well this game comes out tomorrow and suffice it to say I'm buying it. Bethesda seems to have really outdone themselves on this one from what I've seen. Granted, it'll never be as good as the first two Fallouts but it's looking like a solid game with plenty of action and plenty to do.
