After defeating Harry Potter and the Half-Blood Prince I can finally hold my head up and say "I beat all the Harry Potter video games!" This game was a lot better than Part 1 of the Deathly Hallows (everything is better than Part 1) and is just about as great as Part 2, but for different reasons.
The reason that The Half-Blood Prince might just be my favorite of all the games is because it returns to the core of Hogwarts and Harry Potter games. Not only does the game focus on the story very well, it allows for Harry to participate in three different clubs: dueling, potions, and quidditch. By competing in matches and dueling the other houses everything just feels right as it should be before they completely leave Hogwarts in the seventh book.
