I don't tell stories. I ref Role Playing Games. PCs live or die by actions taken and a certain amount of randomity . There are no guarantees in life
Well do you like rolling up new characters very often? T20 characters take a long time to roll up.
Well I suppose an AI program could create characters on the fly as you need them to replace casualties. Maybe it can generate 10 characters for each player, and make them all average Joe cannon fodder types and we can see who survives just like on real life battlefields, who survives and has a story to tell is as often a matter of luck as it is one of survival skill and experience. With leveled characters, you rely on luck on your first few adventures and afterwards after you increase in levels, your ever mounting hit points keep you alive. So if you start with 100 characters and 5 are left over after multiple combat encounters, those five are the heros, everybody else is just cannon fodder, that is what modern battles are about.
Are you familiar with George Armstrong Custer? He fought in the American Civil War, and throughout that war, he was both fearless and lucky, those two qualities made him a hero, he was so lucky, that at times he felt himself invincible as people to the left and right of him, got blown up, maimed killed and shot, he continued to charge into battle, and because of that, he was one of the heroes of the Civil War, his Valor and courage serve as inspiration for many soldiers up to this day, and then at the battle of the little big horn, his luck ran out, I think Custer was more of a statistical fluke rather than being a better soldier than those who were just as brave and fearless as he was but got killed or maimed early on.
