Has anyone else noticed the things Bethesda has done to go out of its way to ignore Fallout: New Vegas? I know New Vegas takes place on the opposite side of the country, but they seem to go out of their way not to reference it in their games and even their merchandise. They also seem to completely ignore new features added by it. For instance, FNV introduced turbo, the chem that slows down time. In Fallout 4, jet now does this. To get the original FO3 and FNV effects of jet, you have to craft jet with flamer fuel to make 'jetfuel'. ...Why didn't they just add turbo? Something else that is strange is that Fallout 4 has a 'survival mode', which is basically just New Vegas' hardcore mode but renamed and with a few extra features like only being able to save by sleeping in beds. Why did they rename hardcore mode? Did they need it to seem original? This one is more minor, but Fallout 4, despite not including skills, does still include the skill bobbleheads like in Fallout 3. All the bobbleheads are based off of all the Fallout 3 skills -- this means there are Big Guns and Small Guns bobbleheads. There is no bobblehead for New Vegas' Survival skill. This isn't just exclusive to Fallout 4 though. An example that isn't from Fallout 4 would be how Fallout Shelter includes only cameos from Fallout 3 and Fallout 4 characters; none from FO1, FO2, or FNV. The Fallout Board Game doesn't have any references to New Vegas either. You can play in five different locations only; the Capital Wasteland (FO3), the Pitt (FO3), the Commonwealth (FO4), the Island (FO4), and (albeit with an add-on that costs extra money) you can even play in New California (FO1 & FO2)! The add-on features characters from Fallout 1 and Fallout 2 as well, like Ian, Harold, and Marcus. They reference the originals before New Vegas. It seems there are more references to New Vegas in Fallout 4's DLCs than in the base game, especially Far Harbor, which I'm pretty sure did not have all the same team members working on it; notably, I believe Far Harbor did not have Emil Pagliarulo as its writer, but I could be wrong about this. Does anyone know of any other examples of Bethesda doing this?
