I don’t want to say much in this thread because I don’t want to break the author gag rule, but I feel like this statement is partially informed by something I said in another thread on the general design forum. So I just wanted to address one thing.
I wouldn’t consider turning a page in a book “interaction” in a meaningful sense, and that’s not what I meant by my comments in the other thread. An “interactive” version of Moby-Dick was released last year where the only thing you did was turn the page to read more text. It was exactly the same as any normal Moby-Dick book you could get in a bookshop. This game was created specifically to prove the point that “turning a page” is not quality interaction.
But it is possible to make a linear hypertext game that could not be transposed to a traditional book format, because the text is structured differently to capitalize on the interactive component. The Moby-Dick game does not require interaction. Something like growth by Liz England does.
