It was already a great game for me, but after replaying it after reading the book, I realized that it has been perfectly made the transition to the game. You can hear many references about statements made on the book, even those who refers to parts that aren´t on the game, like the "missing station" or the "curse" of the Kremlin.

Play it for the story, or for the ambience, or for the gameplay, or for the music, but play it.
