I see. The game is getting good reviews so far, so it would seem that the storyline isn't bothering a lot of players. I can see why you would prefer that it stick to Emily and her immediate family, though. It must be hard for the developers to continue moving the series forward while trying to keep the games fresh, although I think they have done a good job with it so far.
I'm looking forward to playing it. As long as the gameplay remains the same, I am quite sure that I will enjoy it. I hope you will still have some fun with the game.
