There's auditory and visual queues, there's engaging feedback loops, there's built in reward structures, there's failure states, there's built in interactivity. You don't have to force yourself to do the thing and pay attention. Some games like StarCraft may force you to focus more intensely on things outside the actual game to be successful at playing it but a book is quite frankly more boring and less immediate and you have to force yourself to engage with it until it becomes not boring.

Forcing yourself to do the boring or difficult thing until it's not boring or difficult is what trains that muscle.
