counterpoint that you just yourself made: gameplay should take priority.
the task is not to write a book or film a movie, it is to make a video game.
it is not the most orthodox move to have the player really start to unlock the porn in a porn game after the actual game is over. generally speaking, you'd want the story and gameplay to be centered on the porn aspect of a porn game.
and to be clear i was just making a counterpoint, think what you think, and like what you like. i know the devs are going to do what the devs are going to do. it does not matter in the slightest if it makes sense to me what the devs consider important.
