James can't stop buying $20 Fortnite skins. And now it appears Fortnite developer Epic Games is worth $8 billion. Go figure. 

According to Bloomberg (via gamesindustry.biz), Fortnite is set to accrue $2 billion this year alone—and, according to the Bloomberg Billionaires Index, the developer is now valued between $5 billion and $8 billion. This figure includes all of Epic's business ventures, including its Unreal Engine. This also makes Tim Sweeney, Epic's CEO and founder, a billionaire.
