Fallout 3

It seemed like a perfect world. After World War II the USA made rapid advances and technologies. Robots, Hovercars, just everything you can dream of was there. But eventually war raged again and in the year 2077, the dream suddenly came to a halt and mushroom clouds dominated the sky. The lucky people were safely secured in their bunkers called "Vaults". The others, well many didn't survive, others mutated heavily and overall what was left of the world was nothing more than a nuclear wasteland filled with ruins and signs of a once great civilization. Now it's the year 2277 and slowly but surely human kind leaves the vaults and reclaims the lands of Earth. The player is one of them. As a member of Vault 101 in the wasteland surrounding the city formerly known as Washington D.C. and now called "Capital Wasteland". And raised in the vault under the tight rule of The Overseer and the watchful eye of his father he doesn't know anything about what's outside. But on his 19th birthday, his father leaves the vault and the player's goal is to go after him. Learning the truth about what The Overseer concealed all these years on the way.
