So a guy on /v/ got interested when we got to discussing whether or not a game would could be set in another country without breaking the lore too much. (That's another discussion entirely so I'd appreciate it if we could table that till later.) Anyways he brought up some interesting concepts for setting the game in japan and I brought up the game I ran.
So yeah, Storytime.
The Place is Okinawa, the time some years after the events of Fallout 1. But I'm getting a little ahead of myself.
In my version of the fallout universe the hypernationalistic USA converts Okinawa into a fortress island and little beacon of american culture. More importantly it served as the hub of serious technological defences that kept Japan from being glassed during the Great War (much of which have fallen into disrepar for reasons I will go into)
The players are descendents of American Military Personel, in the years following the great war this group of people have splintered into two factions. 13 Blessings and The Destined.
13 Blessings holds the American Empire in a sort of religious reverence but believes that the dream is dead. It's done, time to move on.
The Destined believe in Manifest Destiny and want to restart the glory days of the american empire starting with conquering mainland Japan.
The two factions have battled since their inception and the automated defences of the island (primarily automated flying drones and submersibles) make it near impossible to approach.
