It is hard to think of a more modern entertainment format than the open-world video game. These sprawling technological endeavours, which mix narrative, social connectivity and the complete freedom to explore, are uniquely immersive and potentially endless. But do they represent a whole new idea of storytelling?

This week I met Dan Houser, the co-founder of Rockstar and lead writer on Grand Theft Auto and Red Dead Redemption, who has been in London to talk about his new company, Absurd Ventures. He’s working on a range of intriguing projects, including the novel and podcast series A Better Paradise (about a vast online game that goes tragically wrong), and a comedy-adventure set in an online world named Absurdaverse. He told me that, 15 years ago, he was doing press interviews for the Grand Theft Auto IV expansion packs when he had something of a revelation about the series.
