I was thinking...
Pre-Fallout
Pre-BoS
Vault 15 perhaps
A small number of writers, 4 maybe 5, starting out in a Vault together. Each writer can have 2 characters related or independent.
I hope to set it apart from other stuff by making things more lethal and primitive and by making the writing process more collaborative.
Rather than have a bunch of people writing only as their character we can have each writer put together a larger post involving whatever group they are currently with. We'll switch writers with every post and send him/her PMs in regard to what our characters are going to do.
I'll either PM or write the stuff to move things forward if they get stale.
Generally I'd imagine it being about a small group of people leaving to try to determine what has happened to the world. They find it largely decimated but seek to eek out a living and to make it easier for the next generation. At the same time they're amongst the first people in the area to have left the Vault and see how thoroughly the world has been destroyed. Later on issues will develop with crime in cities, corrupt law in cities, and raiders about their borders.
Does this sound good? Would you prefer a different setting? Would you participate?
Edit:
Any ideas are welcome too. Factions you think would be interesting to see. Themes you think would be cool to cover. Anything. Brainstorm.
