I'm just playing that game and i can say that the first part was fantastic, but suddently once they started that stupid porn movie thing it went to crap.
Everything seemed to have changed at that moment just if it was another game done by some other dev without imagination and talent!
What did happen ?? did the guy who did the writing quit and was replaced, even the technical part was of lesser quality. Renders went from very good to average, animations went to crap, the dialogues became annoying, all the kinky humor and funny situations disapeared for bad jokes and mediocre scenes!!
I had a lot of fun playing this game till that moment but then i had the feeling to play another game in which all what made it special disapeared.
