One under-appreciated breed of fic writer are the ones who hyperfocus on logistics to the exclusion of all canon shortcuts, and thus usually strike upon an awesome way to flesh out the worldbuilding or characters.
Like, I’m not necessarily talking realism here since often it’s still pretty far from realistic, but more like, “someone has to be running spies in this fantasy kingdom, and we’ve seen the whole royal court, so which background character is it? How does that change these three major interactions?” Or “real life historical nobility did in fact have some things to do that were like jobs, how does this human disaster cope with running an estate?” Or “there’s no reason for a sci-fi robot detective to know how to whitewater kayak, where’d she learn?” Or “if this guy is serving the emperor directly he has to be way high up in the space empire servant hierarchy, why is he doing this menial task for someone else? What’s his motive? Does he perhaps have the secret space telepathy?”
Anyway I’m always DELIGHTED to find a fic or writer who asks these questions because the fics themselves are universally bangers.
person who knows how logistical things works has picked up the cannon, hefted it thoughtfully, and put a single chalk mark precisely on the problem.
