Ruth Davidson investigates the brain drain of talent from Scotland's games industry to foreign shores. With major development hubs in Dundee and Edinburgh, Scotland has been at the very forefront of this successful sector of our economy, one which makes more money than either the UK film or music industries. For the last 30 years Britain has been third in the world, behind only America and Japan, in selling its wares to gamers across the globe. So if gaming is so strong, why are numbers falling, studios closing and developers leaving these shores? And why is a seemingly successful industry asking for government help? Following The Investigation, Graham Stewart hosts a discussion on the future of the games industry with Professor Paul Harris, head of Abertay University's new Institute for Art, Media and Computer Games; and Ian S Bruce, technology editor at The Herald.
