That’s the sneaky thing about IP based projects. Even if it was a small indie team, even if they were in love with the original book, even if they had incredible respect for the original author and their work, a book and a game, or a movie, or an episodic show, are so inherently different as to make any IP deal simply a lie. They use different techniques, methodologies, and structures such that they can’t produce anything like the same experience, even with the same plotline. It’s a mask to trick people into buying the product, and the wildest part is that the mask can work so well that even the makers don’t realise it’s a mask.
