If you play a lot of video games, or a lot of a video game, you slowly learn the map, it stays in your head. It doesn’t exist, it’s an imaginary place, but you can find your way around in it, even give directions within it.
A shared fiction is like a shared map, a space we can inhabit, a shared memory palace, even for a brief period.
