I don't really see the point in saying this isn't a porn game just because it has great writing and fantastic humor.
This IS a porn game, AND it has amazing writing, that's what makes it so good. It really does a lot to capture the style of the KND cartoon and yet include explicit sexual scenes in a way that's believable within the setting. I could see Numbuhs 1 to 5 getting into some of the hijinks the characters in this one get into.
