* WhatCouldHaveBeen:
** In general, [[https://tcrf.net/Fallout many things]] [[http://fallout.wikia.com/Fallout_cut_content were cut]] from the game.
** Additional Raider factions (The Jackals and The Vipers) were cut. You could report [[ImAHumanitarian 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.
** 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''.
** The original draft of the conclusion of the Junktown questline was rather [[GreyAndGreyMorality 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 KnightTemplar 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".
