When you talk about why certain genres appeal to certain people more than others then you need to understand that different people have different tastes. Many people love reading romance novels while others love to read modern tragedy fiction. So, as people have different tastes they have different requirements that satisfy their cravings. Many people love fiction because it helps them to trigger emotions and their imaginative sides of the personality like nothing else does. Some people like nonfiction more than fiction. Like I mentioned it totally depends on a person’s taste in books, do you agree?
