A Book is better to get a text narrative across (duh!) because you put yourself in the world. However, games can be as engaging, narrative can be delivered with other means. Have him play "missile command". No flashy cutscenes, no music. The Player creates the scenario for himself and immerses himself in it. No narrative but the game itself but if you immerse yourself in it, it will haunt you.
The MAss effect games will put you in a universe that is full of philosophical issues and Aliens that are actually alien.
