Itll be boring for the first 20 minutes or so.
I have never been so drawn to a game's story. You will really connect with the characters, and be blown away by the revelations.
Also, if you like film noir then this game is for you. Private detectives, dark and damp settings, eerie prophetic music, and the criminal underground are all key elements.
Damn, I want someone to beat it just so I can talk about it without ruining it!
