Novelist and games writer Naomi Alderman asks why video games haven't received the cultural recognition of other art forms.

On her quest, she meets some of the most important and powerful people in today's entertainment industry. They run companies worth millions of pounds and make games played by tens of millions of people around the world, yet they rarely find their way into the spotlight.

She also finds out how writers contribute to the shaping of new game narratives, and looks to the future, when games might well react to the personality of the player.
