This what-if scenario comes from Jurajj, who asks...
What If: Vault-Tec never existed?
Premise: In the mid-21st century, fear of nuclear war is at an all-time low. Believing in the superiority of their country's military, most Americans see the Chinese menace as a simple annoyance. The few nuclear shelter companies that do form are soon after closed by the government for "un-American" opinions. How might Fallout's events be altered in a world where no one prepared for the Great War? No Vaults, no Vault dwellers, no NCR, no Master, no Project Safehouse. What powers might arise in this timeline, and how would regions that should have been devastated or saved by the results of Vault-Tec's machinations be fairing?
