In Game of Thrones, violence serves a great narrative purpose. They often use it in important story moments, such as when a character is in danger or dies. You actually see that in every detail. So it does not create a shock but makes the shock from a character's death stronger. It also feels much more intimate, because of how real it is. You can project your own body and your own senses onto this character. It is disturbing, but this is the main point. As for nudity - well, it does not look like entertaining nudity. It often grim - depict women like sex objects in this world, or shows how characters manipulate each other or simply do not care about each other (like scenes in brothels). I think it fits the setting extremely well, and even if it is sometimes needed only to shock a viewer - it also serves a narrative purpose. This setting should feel uncomfortable. All of this can also be said about the Witcher, but sometimes it feels like Andrzej Sapkowski just wanted to entertain, yes. Well, I guess we need to know that Geralt is successful with women. It does not look like a bad thing. At least it can attract a new audience.

And as far as I know - Forgotten realms is a relatively dark setting too, and the first two games are not fairy tale stories. Hard to say how they would be depicted with modern technologies. Looks like a good D&D setting to introduce all these narrative methods for me.
