Hello
Slaughter Manslaught,
Thank you for your compliment.
I have come up with a plot I feel is good and it has an ending too but I do not want to spoil it in case I may ever be able to pitch it as a mod or perhaps in the unlikely event a full game.
Also, why you want to do another epic plot? I like me a epic, but one of the things FNV did right was not going straight epic save the world thing.
Feels sort of tradition to me.
The local matters to me make sort of the meat of a campaign, helping out settlements and groups, with the big plot uniting them all.
Plus its not a 'destroy the world or kill the mutants' plot, its more about bring some of old world's power back with all of its failures and mistakes.
While NCR does have a presence in my idea it is not a large presence.
In my take the NCR did manage to take control of the dam but they were never able to annex New Vegas thanks to the Courier and Mr House/Yes Man.
Plus as the NCR spread further it became weaker while problems back home only became worse.
I am thinking that the famine that Dr Hildern is perhaps already happening and that the NCR is either on the verge of a civil war due to the problems mentioned in FNV or that that is also happening.
NCR is not the power it used to be and the colony that was send to San Antonio to secure the Sunset Route only has sporadic contact best West, making the people wonder if there is still a NCR.
Regarding your other post, there would be Texas Rangers or a similar organization in Texas (perhaps a different name may better better to prevent confusion with the NCR Rangers and Desert Rangers) but they are an independent group of trouble solvers rather than working for any of the city states, much to the annoyance of Lone Star.
Like
Makenshi suggested, each city state has its own police force and militia.
I wasn't sure about using material from FOBOS or FOBOS 2 Vagrant Lands as that game was not well received for good reasons.
I still like the idea of the secret Vault Tec Vault, the Texas Brotherhood of Steel chapter, and the Super Mutant army led by Attis, that is why I decided to use some of it.
