So i was thinking now theres loads of threads suggesting thing slike this.But in van burren the ncr was in a Civil war between the loyalists and the rebels lead by Victor Presper so if Obsidian ever makes another Fallout game i think it would be cool to base the story around an Ncr civil war over things like Mutant rights -parreling the rights of Blacks and irish that cause the American civil war so just a suggestion and please don't redirect me to another thread thanks.
If an NCR civil war was to happen, I think it would work best if the BOS nuked the NCR capital. The fall of central government leaves a void that several states try to fill - I'd suggest Reno, Hub and Angel's Boneyard claiming the right to be capital and setting up paralell federal governments and presidents - Only Reno and Hub being serious, Angel's boneyard secretly playing and arming both sides to prolong the conflict (and make more cash). Vault City and a few other places try to go independent again.
The game then can be set around the players actions - Restich the union, and with who in favour? Don't restich the union, kill it dead? Have the BOS become the steel scourge theatened in the alternative ending to FO1?
