Within the context of Infinite Worlds this would be considered a close parallel with high historical inertia until 1947.
The people the aliens of the Mothership Zeta DLC kidnaped are not counted as there is nothing to show they were notable in OTL. While the main divergence was the field- point transistor not being invented in 1947 there are indications that the Fallout reality diverged way before that date. Tonewise Fallout is a darkly satirical version of Classic: Atomic Horror with bits of Classic: Illuminati (Vault-tec, Nuka-Cola, Hallucigen, etc) thrown in for good measure. Fallout in the early design stages used the GURPS system but for reasons unclear the deal fell through with Interplay and Steve Jackson Games parting ways.įallout is a post-apocalypse Dieselpunk setting set in a close parallel to our own world that majority diverged in 1947.
