1. at the beginning creator started to make this game because of passion. Now he is making it because of money. Quality cant be the same with these 2 motives.
2. probably at the start no one of hes friends and family didn't know that he was working on the game. Later(now) money started to flow, people close to him must be quastening where are money coming from and he had to explain that hi is making the game where you fuck your mother and your sisters. So to me is like he have some moral problem now. If you just look at how story is proceeding he is entering more and more non family characters. Playing and making this kind of game isn't the same in my opinion.
For the game it self, he should stick with house only. What i liked with this game the most is beautiful and simple surrounding with many different possibilities. And that surrounding have so much more potential for fullfilling with story, that is very good at this point, without spreading it any more. But he is doing all opposite now. He is spreading environment, spreading the story whit new characters.
So if im the writer, only new character in this game would be Olivias mother. Everything would be happening in the house. New angles of every room and the game would be awesome.
Sorry for long post.
