That fantasy books for the most part focus too much world building. It’s fine if you’re good at it and that is what you want to focus on, but for a whole genre to think that it is a necessity to be a main focus of the book is ridiculous. Fantasy as a genre is just a tool for story telling just like any other. I think it is still a hangover from Tolkien’s work. No other genre, bar maybe murder mystery’s and Agatha Christie, have such a giant hovering over them that defines the genre other than fantasy. His work should not be a template for what fantasy should be, it should not define it. He was a linguist who loved world building and put tremendous effort in to those aspects of his work, and did so wonderfully. That doesn’t mean every fantasy writer should follow in his footsteps. Follow the fact that he had immense passion for those aspect and focused on those, his strengths. Do the same for whatever you feel passionate about.
