I could see a game where it’s vitally important to conduct proper funerary rites.
You could design a mechanism that would take the dead guy’s reknown or XP or expertise, and redistribute it among his mates-- with a side chance of really pissing them off.
After Peloa-2, there were funeral orations every few hours. Nine Hibiscus kept the old tradition of a Fleetwide broadcast on a seldom-used frequency, a recitation of the names of the dead. When the Tenth Legion wasn’t in active combat, it sang its way through a thousand years of previous casualties, cycling every week and a half from the most recent fallen soldier in the Legion to the very first Teixcalaanlitzlim who had died wearing this uniform. Nine Hibiscus couldn’t forget his name, or the low tone it was sung on during the litany—Two Cholla. A spear-name, all cactus needles, a name that would have sounded very fine with captain or ikantlos in front of it. Two Cholla had died a thousand years ago, at seventeen, before any titles or ranks could accrue around his name. There were a lot of names that came after his. During active combat, the funeral frequency stopped playing its endless loop of memory and broadcast actual funeral orations, however small and paltry they ended up being. A snatch of song, the sound of blood falling into a bowl, and on to the next.
