While there are a number of "bishōjo" games entirely focused on hardcore pornography, many of the most popular titles, including all those available for home video consoles, do not contain pornographic material, and many others only contain a small amount in relation to the story as a whole. For example, the 18+ version of the popular game "Kanon" contains a total of five sex scenes and two other images of nudity within a branched story the size of a long novel.
