I don't care for them unless the game is specifically centered around them and even then I'll probably end up looking at regular ol' porn...
Usually the writing just goes out the window and I'm subjected to overlong descriptions of what I can plainly see happening before me. I'm good with the anatomy lesson thanks. That and the fact that the girl has to give me a play by play of everything that I'm doing to her. Yes I know my dick is inside of you, and that I'm fucking you, and that your hips are moving on their own, why do you keep reminding me?? (maybe because it's usually blurred out she thinks I don't know?)
Plus by some awful decree every girl in a Vn has to be a virgin so I'm subjected to a whole lot of blood letting. Like do we have to see that? It's gross...
