Harry Potter GAMES : .....
"There are eleven Harry Potter video games, eight of which correspond with the films and books, and three other spin-offs. The film/book based games are produced by Electronic Arts, as was the Harry Potter: Quidditch World Cup game, with the game version of the first entry in the series, Philosopher's Stone, being released in November 2001. The video games are released to coincide with the films, containing scenery and details from the films as well as the tone and spirit of the books. Objectives usually occur in and around Hogwarts, along with various other magical areas. The story and design of the games follows the selected film's characterisation and plot; EA worked closely with Warner Brothers to include scenes from the films. The last game in the series, Deathly Hallows, was split with Part 1 released in November 2010 and Part 2 debuting on consoles in July 2011. The two-part game forms the first entry to convey an intense theme of action and violence, with the gameplay revolving around a third-person shooter style format. The other spin-offs games, Lego Harry Potter: Years 1–4 and Lego Harry Potter: Years 5–7 are developed by Traveller's Tales and published by Warner Bros. Interactive Entertainment. A number of other non-interactive media games have been released; board games such as Cluedo Harry Potter Edition, Scene It? Harry Potter and Lego Harry Potter models, which are influenced by the themes of both the novels and films."
So why would it be different to obtain the license for a pinball machine ? Yes Universal would love more exposure they just invested millions of dollars creating Harry Potter as part of Universal Studios. The franchise is a major money maker with a huge fan base. I think it's only a matter of time before the Harry Potter Pinball Machine is made.
