I’d say if you’ve ever wondered what it be like to just wander about the castle, it’s well worth it. It’s cheaper than going to say universal studios or the Warner Brothers lot in London…
But there’s actually very little gameplay in the castle around areas you recognize from the books or movies. It doesn’t take long until you’re throwing into a very generic game with a thin coat of Harry Potter paint applied. There’s a lot of samey quests and combat doesn’t really evolve ever.
