So this is my idea. It takes place in 2296 in Texas.
Before I get started I'm going to lay down some history on what happened leading up to this idea.
History
After a NCR victory at the second battle of hoover dam, the legion retreated back to Arizona. With most of the legion leadership dead or captured the legion fell into anarchy with the legion dividing into many different factions.
This ended in the year 2282 when a person emerged claiming to be the son of Caesar. This person quickly gained followers and by 2284 reclaimed all legion territory. He started stabilising it and also integrating more technology to improve their army.
Meanwhile the NCR discovered another nation while exploring out past New Vegas. This nation was called the 'United Texan Federation'. Do to shared ideals such as democracy the NCR and UTF became quick friends.
To connect the two nations a old pre war railroad that went through the edge of Arizona and New Mexico located just outside of legion territory.
The NCR has also expanded into much of Nevada during this time and met little opposition due to the legion staying mostly quiet while rebuilding.
In 2285 are annexing much of Nevada the NCR secured the divided and took control of the nuclear weapons their.
Later in 2287 The Legion discovered a pre war nuclear silos with unfired nukes while exploring near Kansas.
After the NCR and Legion discovered that both of them had access two nukes a second cold war started this time between the NCR and Legion.
This Cold war started in the year 2288.
In 2290 the Legion had expanded north annexing many tribes into it's ranks. It has also started recruiting super mutants.
In 2292 the Legion attempted to negotiated with the UTF about them joining the legion. The UTF refused.
In 2293 the Legion begins a invasion of the United Texas Federation. The NCR is unable to help due to the fact that the Legion has nuclear weapons. The Legions sweeps through northern Texas with the UTF unprepared to defend themselves from such a foe.
By 2296 over half of Texas has been taken over by the legion. With constant war going on in the middle. The NCR has been secretly sending rangers to help train UTF troops and have been given them weapons.
Now that we got that out of the way let's get to the story of the game…
Story
You are the Outcast. You were born into the Enclave before your bunker was destroyed by NCR forces and you were forced to integrate into the NCR. But after your heritage is revealed you were forced to leave the NCR or face punishment for the crimes of your family.
You fled to the UTF where no one has ever heard of the Enclave before to live in peace. This was until one day when the Legion started invading. Now the region is in a state of constant war between the UTF forces and the Legion invaders.
The Game starts with you waking up one day and doing you normal routine. Washing your face while looking in a Mirror (Character Creation). After doing that you hear a voice telling everyone to come outside.
After leaving you small one room house you see that the UTF are conscripting people. You get conscripted and then must fill out a forum and get asked a few questions (Tags, Special and Naming). You then get a really quick crash course on being a soldier (Tutorial).
But before you can complete you training and officially become a soldier the Legion attacks, killing most of the conscripts and soldiers leaving you one of the few survivors. Where your story goes from here is up to you….
Factions:
The United Texan Federation: This is the federation that once controlled most of Texas. It is now struggling to defend against the invading legion.
The New Californian Republic: The Republic which controls Californian and Nevada. It has been sending rangers to secretly help train the UTF troops.
The Brotherhood of Steel: Are allied with the NCR currently and are also secretly helping the UTF for the NCR. This is their first time in Texas and have never ever been their before.
The New Caesar's Legion: Formed after the old Caesar's Legion fell into anarchy by a man who claims to be the son of Caesar. This person is known a Caesar the 2th.
The Enclave: Made up of a few tiny scattered hold outs and remnants. Mostly exists in Chicago.
The Texan Resistance: The general term for the rebels in Legion controlled Texas.
Companions
Note: These are only the ones I come up with now. These aren't all of them
Linda Homsom: A desert ranger who left when the NCR annexed them. Carries a hunting revolver.
Jerry Yonder: A ghoul who was a pre-war soldier. He has a deep hatred of anything communist and sees the Legion as the second china. Carries an assault rifle.
Rebecca Bishop: Is the daughter of the bastard son of the Chosen one. She moved to the UTF because she didn't want anything to do with mobster stuff. She is also still pretty loyal to the NCR despite moving away. Carries a laser pistol.
Cato Fabius: Is a legion agent who will join you if you side with the Legion. Carries a shishkebab.
Well That's the end of my idea. What do you think?
I reposted this and deleted my original post because I didn't like the title I made for it.
