This video game is actually the final installment of the traditional Harry Potter role-playing games of the early noughties. Harry Potter and the Chamber of Secrets and it's prequel Harry Potter and the Philosopher's Stone, like this one, follow their own canon separate from the book and it's film adaptions. The characters have models based on their book descriptions and Hogwarts layout appears very much to be an original interpretation. Starting with Harry Potter and the Goblet of Fire, the video games based itself entirely on the film canon, removing spell challenges, chests, inventories etc.
The first installment in the Harry Potter Video Game series where characters Hermione Granger and Ron Weasley are playable in addition to Harry himself, each with their own set of skills and abilities (with choosing just the right one often the key to advancing through any given task).
The final game in the Harry Potter series in which Peeves the poltergeist appears in.
