How "Game of Thrones" changes everything

the series Game of Thrones changes everything, as far as fantasy goes. For one, it goes back to the world-building tropes, that were present in Dune. Plus, we are now entering into the 5 families fiction, a trope, where we follow at least 5 great families, as seen in War and Peace. Also, this series is weird, as it does not revolve around the lives of children or teenagers, but rather adults. Fantasy comes from fairy tales, which tend to be about little children or teens who try to make one's way in the world. One need only think of Grimm's Fairy Tales here. Disney even once centered fairy tales around babies. Water Babies is also around the baby fantasy trope. Harry Potter, Red Queen, Divergent, We, Narnia, and Ender's Game all go around teens having adventures. But now, it is all about grown ups. We'll have to see how well the public likes having everything change.
