Update after a month of silence for self reflection planning and work: Server has been purchased and is up and running. It's still a completely solo operation at the moment just me working on my own.
I've decided to start the game inside of a vault with the condition of the outside world left a mystery. The idea is that as the player-base expands the game will expand to match.
I'm going to use inspiration from the canceled Brotherhood of Steel 2 that I've been able to gleam from some research and what may or may not be a design document. Though I suppose the authenticity of it doesn't really matter considering how far from canon the original Brotherhood of Steel was. Still just going to use them for some ideas, and the vault the game takes place in is going to be in the city of Lonestar from the BoS sequil.
At that it's going to be a government vault consisting mostly of military and government personnel from the state of Texas with an emphasis on maintaining a governmental structure and actively trained military through the use of those fancy handy dandy simulator pods in order to prepare for the reclamation of Texas.
Will this group turn out more Brotherhood of Steel or Enclave? Who knows but right now that's the setting I've settled in on. I've got a good chunk of work done on setting things up but it's been a little slow so far since I don't really know what I'm doing.
Still rest assured I'm sticking this through since I've already prepaid for server hosting for the next year or so.
