The video game industry earned $8.47 billion in digital sales for August, according to the latest figures from SuperData Research. This represents seven percent growth over last year, driven by pay-to-play PC and free-to-play console titles.

On PC, World of Warcraft‘s Battle of Azeroth expansion was a big hit, earning Blizzard $161 million. This doesn’t include pre-sales leading up to the launch.

Mastercard recently signed with League of Legends as the game’s first global partner, which will offer its cardholders VIP esports packages. With new exposure around the competition circuit, Riot Game’s title could bounce back during the World Championships beginning October 1.
