Tastes differ, methinks. And one of the main differences IMO between Sandbox style games and VN style games is that the former feel more like a game, the latter more like a novel or movie. Nothing is inherently wrong per se, but personally I like to do some stuff to earn my rewards, even though I like me a good VN, too.
But as with many tags, it is a question of what you like. Don't want NTR? Don't play NTR games. Want NTR? Don't play non NTR games. Generally I think it is good a variety exists for all people, even if I am missing out on one or two gems because they go the wrong direction. But even though I don't like competitive FPS games, I don't go on forums for them and complain that they aren't made differently, I just ignore them.
