Beyond cashing in on the success of the franchise, a developer should always remember that it is very important for fans playing the game to see and experience the fictional universe in the exact same manner that their favourite characters do. Though the story and presentation of Harry Potter and the Half-Blood Prince got hung upside down (Get it? Levicorpus!), Bright Light Studio were pretty close to the mark with the gameplay. While it may not be very challenging, the magic of the world that J.K. Rowling has created has definitely rubbed off on this one.
