For your reading pleasure, allow me to note a moment in my thesis where I mention the Fallout series:
 
" The post apocalyptic setting is a common science fiction setting often termed as a sub genre. It is also a setting used in popular genre works outside of literature. The 1968 film Planet of the Apes for example takes place in a post nuclear environment as do a number of popular video games including the Fallout series. The post apocalyptic setting allows the artist to explore a destroyed world while raising issues associated with the cause for the disaster, in the two examples above, the fear of a nuclear war. Similarly, The Road uses its setting as a comment on modern environmental concerns. "
