I have played this till the day after the awards for now, I like the story so far. The dialogues in their family feel natural and I think the graphic/models are good too.
If not for too many criminals at the same time and too much of a feeling of "siege" on the family it would feel realistic enough.
The bodyguard is weird though. He feels not so professional after all (aside for what is up to player decisions) and even quite unstable (the way he refers to Emma "I will protect you this time" or something like that... damn creepy)...
For instance he is also talking way too much when not needed or even when it could be dangerous. Revealing things that can easily be used against him (the phone thing that he revealed to the cop for absolutely no reason) or against his clients, or possibly put them in danger like talking about where and when he will bring Emma for running, while talking to the bartender that he knows well as a pervert, in a bar where someone could hear.
With his mental issues about Emma the MC should be on the top of the list of suspects about the real danger hiding behind the stalker.
