- Divorced Installment: Originally the game was going to use the GURPS system for character creation, and was entitled Vault 13: A GURPS Post-Nuclear Adventure. Disagreements with Steve Jackson led to the termination of Black Isle's GURPS license, so the developers cooked up the SPECIAL system for the game and changed the title to Fallout.
- What Could Have Been:
- In general, many things were cut from the game.
- Additional Raider factions (The Jackals and The Vipers) were cut. You could report Iguana Bob to the Hub police (and is in fact a requirement for one of the endings, which you naturally cannot get in the final game). In the Mariposa Military Base you could have taunted a super mutant into lowering some energy barriers. In the L.A. Boneyard there was to be a gang (the Rippers) in the Deathclaw Warehouse with associated quests (the cybernetic hand of the leader is a dummied out item itself!). Also a cut area named the Burrows where FEV-mutated raccoons lived (the only thing in the game that remains are a few things in The Glow, such as a holodisk detailing the raccoon experiment). You could also get addicted to alcohol. One removed encounter was of a caravan wrecked by a super mutant (that also perished) — whom you recognize as a previous Vault Scout sent before you. There was also an invasion ending for the Lost Hills Bunker where a (dummied out) traitor of the Brotherhood would sell out the location of the bunker to the Unity, which you could prevent. Etcetera, etcetera.
- The original draft of the conclusion of the Junktown questline was rather morally grey, with Gizmo turning the town into a grade-A resort in which society flourished, although for a mainly selfish reason, and on the other hand having Killian become a Knight Templar who ends up ridding the town of crime once and for all, which also causes a slow depopulation of the place, as people would start to avoid it in fear of the overzealous sheriff. This was scrapped for the final release after the marketing department decided that the game had to "reward good and punish bad".
- One of the concepts dropped from the game during development to meet release deadlines was a race of FEV-mutated Noble Savage raccoons, descended from two pairs of FEV test subjects that escaped from the research facility that ended up as the Glow. It was scrapped because to the devs, the idea didn't feel Fallout enough; as such, the only hint left in the game about their existence is the FEV experiment holodisk at the Glow mentioning that when the virus made the test subjects smart enough to escape from the laboratory, the guards hunted them down and exterminated them, but two pairs remained unaccounted for.
