Rapelay, IIRC, wasn't so much a visual novel as a flat-out rape simulation game. You could follow the girls around, then kidnap them, knock them up, etc. It was pretty intense. It received the attention it did because of its ability to be purchased on English-speaking Amazon, according to Wikipedia. How people can crucify games like this but then play things such as Manhunt doesn't really make sense to me.
