Its a different type of game to things like summertime saga, and overcomplicating the game by adding new gameplay mechanics would mean less time towards adding more content. I have also played many adult games and can say this is still a top tier game with out these features.
You are right Jmike but it can't be denied if the game had those over complicated mechanics it would be surpass being a Dik and all other games it would the greatest top tier adult game in the world Being a Dik developers did it so it's not impossible and this game can be so much better than it if managed correctly. Don't get me wrong I love this game and I'm looking forward for more episodes and season but adding a variety of gameplay mechanics may appeal to a wider range of gamers bringing in more revenue, not all players want to feel like their reading a book they want to be in control.
