Epic Games. Microsoft. Riot Games; owners of the biggest computer game titles in the world and part of a gaming industry which has been valued at $200 billion. That’s more than the music and entertainment industry combined. It’s not all plain sailing though.

Epic Games, which created Fortnite, recently cut 870 jobs. Microsoft, which now owns Activision-Blizzard; famous for the Call of Duty and Red Dead Redemption series, announced 1,900 job losses earlier this year. League of Legends maker Riot Games reduced their workforce by 10%, which meant 530 job cuts. It’s estimated that 18,000 jobs have been lost over the past couple of years.

Zimbabwe has a brand new currency; it’s called the ZiG (Zimbabwe Gold) and it’s backed by the country’s gold reserves. This is the third time they’ve launched a new currency in ten years and 80% of transactions in the country are now carried out in US dollars. Can the government persuade its citizens that this one will remain stable and not deflate?

The BBC’s Zimbabwe correspondent Shingai Nyoka explains how people pay for stuff in the country and why the government has brought in a new currency. Two guys in Harare tell us what they make of the ZiG, and whether they’re using it instead of the US dollar.
