This game is going to focus heavily on how a sense of finality or fatalism affects people. There is, realistically, no ending for these characters other than death - either death in battle, or being executed for desertion. They exist in a society that they're no longer really a part of. They fight to protect a world that they are, in some ways, no longer welcome in. How does that impact them on a personal level? And what kind of person would sign on for this sort of duty? What motivates someone to give up their chance at life, attend their own funeral, and sign up with a military unit that will keep throwing them at things until they die?

Despite the military nature of the game, this is not a purely combat-oriented game, or even a primarily combat-oriented one. There will be a lot of social and character development content going on.
