From a literary point of view, 'A Game of Thrones' is a better-written novel that uses a vast character base to propel an intricate story across two continents. The sheer complexity of the story towers 'Harry Potter' where there are many weak points in J. K. Rowling's storytelling. However, many choose 'Harry Potter' because it is calming and does not put the reader on a rollercoaster of emotions.
