Il setting del primo Fallout è questo:
Converrai a questo punto che si tratta palesemente di un'ambientazione post-apocalittica, per quanto riguarda invece Fallout 2 sono d'accordo e l'ho già detto più volte nei post precedenti...The world that remained was harsh and unforgiving. 90 years after the Great War, humanity continued to survive, but struggled to do so. Above ground, small bands fought over the crumbling remains of once great cities while mutants prowled the irradiated wastes. Underground, a fortunate few enjoyed the relative safety and comfort of the Vaults, designed before the war, seemingly to protect residents from the nuclear destruction. Some sought to keep the world out, others to connect with and re-populate it. Wherever humanity survived it was under constant threat by psychotic mutants, rogue machines, vicious raiders, and all manner of hostile mutant creatures.
