the danger of havin an epic story that takes a long time to finish is like, the fans end up more invested in the world/characters than the author and will remember all sorts of details the author didnt think of, or their fav character will be some character the authir was never that invested in and had no longterm plan for, etc. and the linger it takes to finish the worsr it gets bc the fans hav so much time!!!

this phenomenon is something that kinda scares me as a writer haha
