Just out of curiousity and in case you keep track of that:
How many named NPCs / NPCs that played an important role? How many of them died /survived?
Did the PCs care about it?
I think we had about 80 named NPCs. Many died. Sometimes PCs cared. I don't know how to measure importance. Here's an excerpt from a G+ conversation we had prior to the final session (where a whole lot more named NPCs died):
R.I.P.
Harridan, middle-aged, father of Daff, exploded by the Queen of Bleak in the Ring of Coruscation. Your heart stayed true.
Daff, fourteen, daughter of Harridan, branded to death for mutiny against the Torches of Surtur. Your despair was your greatest strength.
Tem, young adult, twin brother of Thao, rider with the Blue Eagles, mouthed off to Kite. Your brother dearly misses you.
Princey, young adult, onetime Keeper of the Flame of Surtur, maimed by Newton, died under Mei's care. We never saw you whole.
Baby, youngest son of Domino, savaged by hummingbird people, died under Mei's care. Catalyst.
Clubs, older, erstwhile leader of Iron Church, died under Mei's care (when Domino opened fire on everything in the room). Your inestimable wisdom died with you.
Mei, young adult, Angel with the Torches of Surtur, rider with the Blue Eagles, spirit tree aficionado, had throat cut by Burroughs. Quested for tragedy. Found it.
Flamingo, middle-aged, erstwhile leader of Iron Church, shot by Kite. Didn't afraid of anything.
Prexy, teen-aged, assistant to Dealbreaker, had throat cut and eye stolen by Burroughs. Your spark never caught.
Dealbreaker, middle-aged, owner and founder of Dealbreaker's Life and Death Emporium, had masculinity seized by Domino. Deserved worse.
Shark Week, adult, citizen soldier of Amara, killed in battle with the New Eagles at the Fridge. Marble Slab will be holding a story circle in his memory tonight at sundown. Bring water.
Captain, leader of the Silver Guard of the Reef, assassinated by Kite. A cog in the wrong machine.
Logan, young adult, slave to the Pole People, gunned down by Whitmont. Finally free.
Magda, Flamingo's right-hand. Loyal and stalwart to the end. Gunned down in the course of Flamingo's murder.
Newton, whose only flaw was ambition, murdered by Kite.
Mangle, leader of a once-great chopper gang. Had not the soul to lead nor the mind to deceive, but the clear and simple consequence to accept a lamentable fate at Domino's hand.
