We Know What Happens
One problem is that we know what happens 170 years later. This removes the mystique from some of the events of the show. It also makes it difficult to invest in the possibility that the world is in peril from the events of the day. This is a big problem for showrunners and writers to overcome.

Game of Thrones deals with ‘The Long Winter’ and the impending end of the world. It will be challenging for House of the Dragon to achieve the same effect because it’s less significant. HBO knows this so it will be fascinating to see how they deal with it (via Men’s Health).
