Your character was born some 200 years after the nuclear war in the safe, sterile confines of Vault 101.
Fortunately, you never had to experience the horrors of a nuclear holocaust. Unfortunately, your mother died during childbirth, and you were raised by your father (in a very scientific fashion). Your early, developmental years play an important part of the character creation process and double as a basic game play tutorial. The G.O.A.T. (Generalized Occupational Aptitude TEST) determines what some of your starting skills and skills will be. Physical, artistic attributes can be customized as well. Much like the first level of The Elder Scrolls IV: Oblivion, you can manually alter your starting stats and skills before you venture forth.
