Well, I've played the update to end (I always start from beginning for the best experience) and I can say the new models aren't as bad as I initially thought. Lucy's model has become more soft and balanced since version 0.8, which is good. Sarah's model is too young (remember, her eldest daughter is 23 years old) and looks like her older sister, but that's a matter of taste.
It would be really nice to update Benjamin's model, as the story is heading toward direct conflict, and it's hard to take him seriously with a "childish" model.
I'm still interested in continuing the story with Mia, and possibly Lisa, but with Lisa, probably in a friendly way, not as lovers. Having relationships with mother, eldest daughter, and youngest daughter all at once is a bit much :-)
Thank you for great game, one of the best in genre.
