Based on Bethesda's Fallout games they want the world to be in a perpetual state of everyone grubbing in the dirt as scavengers like it's mad max minus the cars, and the West Coast games are the exact opposite of that as they are all about humanity moving on. Though by the same token I also don't think we'll get another West Coast game since Bethesda seems intent on keeping themselves contained to the East Coast so as to avoid acknowledging the games they didn't make themselves. But if house is alive, a lot can change, he has lots of plans for new vegas.That is my take It would keep with the theme of the West Coast however of society rebuilding and returning to its former self, so for that reason I do believe that it would be the chosen ending. Its doesnt seem to have a lot of ideas for the story. I think having the NCR win the Dam is the most boring ending ever, things just go back to normal. Each of them have different narrations and different events. Originally posted by Mr_Faorry:There isn't one, but if they ever revisit the West Coast and have to make one I'd most likely just be 'NCR won at the dam' (yes I believe the NCR would be the canon one should they do it) and then the details of everything else are left to your imagination and just never mentioned. There is no right ending, theres the NCR ending, Caesers legion ending, Yes man and mr House.
