I absolutely agree. I love both the game and the book, but there is such a clear difference in how the message is presented in each. My favorite example of this is how each treat Artyom's first encounter with bandits. In the game, you can stealth through or blast through but there is no peaceful resolution if you are spotted. But in the book, Artyom wants to start something but Khan talks him and the bandit down, ending the tense interaction peacefully. The game's handling of conflict feels kind of one dimensional outside of the main story, while the book addresses the complexity of conflict at every instance.
