The company says this move was made possible both by increased Marketplace growth and Fortnite. "Thanks to both the Marketplace's growth and the success of Fortnite, Epic now conducts a huge volume of digital commerce," Epic CEO Tim Sweeney said in a statement. "The resulting economies of scale enable us to pass the savings along to the Unreal Engine Marketplace community, while also making a healthy profit for Epic."

As for that Marketplace growth, during the first half of this year, Epic says it experienced a 30 percent growth in active sellers. The Marketplace now has over 1,500 creators selling more than 5,000 products and more than 8 million downloads have taken place since its launch. As of July, over 6.3 million users have chosen Unreal Engine 4 -- an increase of one million since March.
