Um. No, I can comprehend just fine, sir.
But that is NOT the point of AVNs. The key is the A bit.
There's plenty of great games which just use the VN format. Once you add the A bit, you are stuck either narratively, in regards to the adult content, or stuck in regards to narrative strength. They tend, as I just explained, to not be conducive to each other.
A strong narrative, often means the story finds ways to juts ease in the adult content naturally, and logically, dictated by the story...... but that often means paltry amounts of adult content, often done poorly, without the focus and care it should have.
A game with a lot of adult content, covering all kinds of fetishes and taboos, by necessity often has to have some fairly absurd, at the least, writing, often times some unbelievable crazy premises, and tenuous associations and logic.... otherwise the scene cannot be set for that intense BDSM Orgy that is a thing in the game... along with many others.
About the ONLY games which do both naturally, are games where the sexual nature of the MC, or the ultra sexualized nature of the world, are CORE traits not only to the character and world, but the main story plot itself. BUT, that is VERY limiting.
So, what side should the AVN author fall on?
It is an A VN, not a VN... the game is meant to be an adult game, with adult content. Adult content at the expense of narrative strength ALWAYS WINS as far as I am concerned.
Maybe you are playing the wrong kind of games? Perhaps you should seek more mainstream VN format games.
