i feel like people call it "goon material" because there's an excessive amount of NSFW and NSFW reference in the early parts of the plot with very little horror until quite late. Honestly barely managed to read through Murdoch's route because for the early parts sam mentions blowing Jim at least 5 times to the point of excess. If the NSFW happened later into routes it would probably be more understood
Quick sidenote, after manually censoring the entire VN upon a friends request (he's only into the horror part) i found out there is about 180 NSFW images with full nudity (including variants)
