The most powerful game engine in the world is your player's imagination.
At least, that's the angle game designer Sam Barlow took in his GDC 2016 Narrative Summit talk about lessons he'd learned in making Her Story.
Released in 2015, the award-winning non-linear game afforded players access to a searchable database of live-action one-sided video clips to make sense of; in the process of doing so, many players found themselves creating pages of notes about keywords and theories about the game's plot and characters.
In his talk Barlow outlined why he thinks that happened, and explored how a powerful, compelling game can be built around that core if you can figure out game structures and mechancis that empower your players' imaginations.
