I haven't played the whole thing yet, but this game has the best comedy for a porn game. Not to mention the mystery, pinch of horror, and action. Incredibly intriguing, especially with the characters' chemistry.
Edit: This game has everything! Overarching mystery, some thriller, a sprinkle of horror here and there, action, and A HEIST! And of course, the romance and sex. Not to mention the music and overall directing of the scenes. Amazing!
