The game follows the events and characters of novel, and film.. The game uses an improved version of the group casting mechanic found in the Harry Potter and the Prisoner of Azkaban. Improved graphics mean the characters themselves more closely resemble their film counterparts than in previous games. Gameplay in the Goblet of Fire is much more action-oriented, which is a change from the puzzle and adventure elements found in previous games of the series. (wikipedia.org)
