I agree that Nintendo is within their rights on this, as much as it bums me out.
I also really, really hope Bitmap Books can cut a licensing deal with Nintendo. And I'm surprised they didn't try that up-front. Or worse, they did, and Nintendo said no
But I'm not 100% sure your Disney Parks analogy is a good one. When I go to a theme park and take a photo, that photo, that composition, is mine there's a unique element, it's an original work, even if the subject isn't mine, and that makes a difference. Case in point: there are a lot of books that are just photographs of the parks. For example,
this book on Tokyo DisneySea has been around for a long time, and I highly recommend it!
That's not the case with a screenshot, though. Those pixels don't change
they're either there or they're not.
