Most zombie games focus on survival and very few games have the narrative depth, for instance The Last of Us or The Walking Dead. What makes storytelling in zombie games so difficult? Do you like open-world survival or a story-driven experience?
 
It's true that there are few story-driven zombie games. I do want to see more like The Last of Us.
