Has no one ever written an episodic domestic timeskip fic? Like, not on a macro scale, just around 2-5 years or so. Writing how ponyville and the ponies in it have changed over the years.
It'd show how the world and the characters have all developed, as well as being able to add new characters and plot lines, and adding returning characters to create new scenarios and incidents. One (or multiple) of the M6 could be written as having foals depending on how far time has been skipped. Like, exploring how AJ’s farm, the boutique, RD’s career, or Pinkie’s bakery are going, as well as how it affects both them and the people around them. Some might not even be in ponyville anymore, like RD being a wonderbolt or if it's pre-alicorn (ideally) Twilight being in the middle of studying to be an archmage and whatever that entails. Showing how the fillies have grown up and how their relationships have all shifted in their tween/young teen years.
You'd think that that'd be one of the more popular premises to write for but I can't recall any that are over 20k words and in an episodic format.
