Games like the Fully Automated! Solarpunk RPG (npub19f4…2hh5) base most of their systems around violence hoping for the narrator to fill-in the community aspects.
I would flip that and gamify the systems of non-violent conflict resolution, especially if those are not us-against-them conflicts, but for example disaster relief / resource management.
Give players the good "number go up" feeling when helping community, not actively resorting to violence.
