World of Warcraft: Shadowlands sold more than 3.7 million copies in its first full day on sale, Blizzard announced today.
That topped the company's previous day-one high, Diablo 3's 3.5 million copies sold upon release in 2012, and prompted Blizzard to label it the fastest-selling PC game of all time, based on internal sales figures and "reports from key distributors."
