Has anyone had a game with a crew full of war veterans? I had a (possibly bad) inspiration where the Flashback mechanism could be used both in the usual way, and also as actual IC flashbacks to the war.
This idea came from reading a new book, Hero of the Empire, about Winston Churchill in the Boer War. This could be a great source of inspiration for the Unity War, with armored trains, guerilla war, POW and concentration camps, early celebrity culture. War service gives a great justification for knowing odd things and people outside your usual social circle, too.
