I don't know about the Witcher 3: it basically opened with softcore porn and I was immediately too turned off to continue with it. Several people who are huge fans of it later told me the wank bank material is pretty much an essential part of the Witcher experience, so I filed it away as a similar cache of any number of romance books on Amazon. Which, to be clear, makes a ton of money, isn't easy to pull off consistently as a product, etc etc. I just don't know if I would consider it great literature.
