We all know that Fallout New Vegas is an incomplete game, and that Obsidian wanted to do things that were never made because of one reason or another. So I am making this thread to record what we know of how Obsidian wanted Fallout New Vegas to be and the reasons why the final product is not like that (if known). Playable Ghoul and Super Mutant race: Obsidian wanted the player to be able to make Ghoul and Super Mutants characters. It wasn't implemented due to how hard it would be to do so using the game engine. Larger game world and locations: Obsidian wanted to have a larger world with more and larger locations. It wasn't implemented because of lack of time, console hardware restrictions and Bethesda saying that from each landmark in the world, the player has to be able to see another three landmarks (making the world have to be more compact). A specific town/settlement couldn't be used: This one is sketchy, but apparently Bethesda told Obsidian not to use a particular town/settlement in Fallout New Vegas. I don't think the town name was ever revealed. A more "morally grey" Caesar Legion and explorable Legion territory: Caesar's Legion was supposed to be represented as a more "morally grey" faction than it ended up being in the final product. The player would also be able to explore Legion controlled territory and a number of "civilian" Legion settlements. Not implemented due to lack of time. A less buggy game: Any developer wants to release a game without bugs, but Fallout New Vegas was released in a very "broken" state. Obsidian gets a lot of criticism about releasing very buggy games, but that criticism is misdirected, because it wasn't Obsidian's fault. Bethesda was the one doing the testing and QA of Fallout New Vegas, and it did a very poor job. Ulysses was supposed to be a companion in Fallout New Vegas: Ulysses was planned to be a companion in base Fallout New Vegas, but it was cut off from the final game. It then reappears as the main antagonist in the Lonesome Road DLC. Fallout New Vegas was supposed to have and use the Child at Heart perk: The Fallout 3 Child at Heart perk exists in Fallout New Vegas, but it is not obtainable without cheats. There is still also content in the game where the perk would be used. The cause for cutting this content was most likely the very short amount of children featured in the game. Floaters were supposed to make an appearance once more: The Floater enemies from Fallout and Fallout 2 were supposed to appear on Fallout New Vegas too. Probable cause for not being in the game is lack of time. There was supposed to be more traits available and they were to be picked by filling in a medical history questionnaire: The questionnaire contains 13 options (doesn't contain one for the Wild Wasteland trait), while the game was released with 10 traits (including the Wild Wasteland trait). The reason why it wasn't implemented is unknown, but it might be due to the engine, since it could be hard to make it so the player can "tick" the boxes and/or to implement new traits added by future DLCs (for example Old World Blues adds 6 more traits). Some trait descriptions are similar to Perks, so there's also be the chance that some of those planned Traits were turned into perks instead. Spoiler: Medical History Questionnaire From the top option to the bottom one we can identify these Traits: Four Eyes Unknown Trait Unknown Trait Unknown Trait Small Frame Fast Shot Unknown Trait (This description seems similar in part with the classic Fallout games "Good Natured" trait) Trigger Discipline (This trait differs from the questionnaire description because it applies to all guns and energy weapons, instead of only applying to automatic weapons) Unknown Trait Heavy Handed Unknown Trait (Could be related to the "Jinxed" trait, from classic Fallout games) Unknown Trait Loose Cannon Courtesy of @Alphons (link to post): Primm was supposed to have reputation: The settlement of Primm was supposed to have a reputation system like some other settlements in the game. Lack of time and/or lack of content might be the deciding factor to not implement this. Myers was supposed to have his own deputies, that were also former prisoners at NCR CF: If you resolved the quest to get Primm a new sheriff by picking Meyers, there would be deputies. Probable cause for not being implemented, lack of time. Both Freeside and Strip were supposed to be only two zones (not 4), while Westside and North Vegas were supposed to exist in the world zone (no loading screen to enter): The cause was console hardware limitations. There was supposed to be a pack brahmin companion named Betsy: Game files indicate that it was somehow relevant to Freeside's North Gate, which contains a cut cattle pen with a gate. Probably a temporary companion. Probable reason to not be implemented, lack of time. Rotface had an unmarked quest: The way it is now, Rotface will get tips and buy a hat (Eulogy Jones' Hat). But that unmarked quest was much more than that. It was probably cut because of a lack of time. If you freed Benny at the Fort he would later try to kill you: If the player saved Benny from the Legion, he would later ambush the player while using a Stealth Boy. Probable cause for not being in the game was lack of time. Ability to play after completing the game, with all consequences from the endings: For example, if you didn't kill Fiend leaders McCarran is a mass grave. The reason for not being implemented was lack of time. There was more to that scene, where Van Graffs shoot that guy when you first enter the store: He was supposed to be pushed from stairs by Jean for flirting with Gloria and then killed. Probable reason to not being implemented, the game engine. Stein (Nipton mayor) was supposed to appear as either a corpse or alive: Now he's a skeleton. Probable cause lack of time. Courtesy of @Atomkilla (link to post): The Courier and Cass married: Obsidian considered having the Courier and Cass get drunk and getting married by the King. The reason why its not implemented is that it would be too complicated. If you can remember any more things please say something and I will add them to the list.
