A few months ago, 16-year-old professional gamer Kyle Giersdorf, known online as Bugha, took home $US3 million ($4.3 million) after winning the inaugural Fortnite World Cup.

For those unfamiliar with Fortnite, it’s an online, multiplayer video game where players fight it out in a post­apocalyptic battlefield, with the last one standing declared the winner.

Since its 2017 release, Fortnite has reached some 250 million players worldwide and reportedly generated billions of dollars for its developer, Epic Games.

But the game has also generated controversy amid concerns children as young as nine are becoming addicted to gaming; concerns perhaps vindicated by the addition of ‘gaming disorder’ to the latest edition of the WHO International Classification of Diseases (ICD-11) last year.
