The man in charge of the company that makes "Fortnite" is now worth over $7 billion. Epic Games CEO Tim Sweeney is No. 194 on this year's list of the world's 500 richest people. Sweeney isn't confirming the number himself; it's based on his presumed sale of Epic Games stock during a recent venture fundraising round. Though "Fortnite" launched in summer 2017, the game's dominance has continued steadily throughout 2018.
