Also. Each (or most of the towns) are dependent of other towns, what town A doesn't have, town B exports it to them. Pretty idiotic move to pull a war then if you ask me.
For cities north of Shady sands they would have so much more to loose if they tried to fight NCR. You got to imagine that these are towns we are talking about are in a post apocalyptic wastelands. There isnt thousands of people in cities/towns anymore. Also you have to know that when you take any amount of people from such a small community you will have an adverse effect on your own survival.
The only organizations capable for war is The Enclave, BoS and NCR. Each of those groups usually tend to ignore each other so there isnt much reason they would go into war with each other unless something major had happened.
Of course the only reason there would be
war in the wasteland would be because the Enclave finally decided to "restore" the pre-government authority.
The way i see it happening is....
1)Enclave would first attack BoS (this would work as at the current time as BoS does not have access to Vertibird tech, along with the Enclave superior technology. One could imagine the fight to be like Helm's Deep without Gandalf)
-if they succeeded I'd imagine, depending on their fighting situation, would either
A) Launch a surprise attack on all of the NCR cities. ( I do believe New Reno would join in the fight with the Enclave against Vault City as they both seem close)
B) Offer NCR some sort of ridiculous surrender agreement which would be called "Ratification of Statehood"
Then again this is FOnline 2238.... if a story line like this was to be accepted into game-play one could see players all around joining the fight for whatever side they choose. I would love to see players traveling to various cities in arm to repel Enclave attacks. Even if this isnt possible an event in which players defended cities against Enclave would be pretty cool.
I'd imagine it would look like the Kansas City Mission in Fallout Tactics except instead of super mutants attack it would be Enclave members.
This location and its associated mission is a highlight of the Fallout Tactics game. Some seconds after you arrive the ghoul town will be ambushed from three directions; north, west, and south. http://fallout.wikia.com/wiki/Kansas_City
