What are the world's Top 5 video game markets? A Foolish Take

Fortnite may be a free video game, but it's already earned $1 billion this year, as well as a cult following. A crowd gathers to buy copies of "Call of Duty: Modern Warfare 3" during a launch event for the highly anticipated video game at a GameStop Corp. store November 7, 2011 in North Las Vegas, Nevada. The worldwide video game market could grow from $137.9 billion this year to $180.1 billion by 2021, according to Newzoo. The research firm also expects the top five video game markets to generate nearly $98 billion in revenue this year. China famously banned video game consoles for 15 years (2000 to 2015) due to fears about their impact on children's development, but that merely turned PCs – and later, mobile devices – into its main gaming platforms. China is now home to Tencent (NASDAQOTH: TCEHY), the largest video game publisher in the world.
