Blizzard announces Battle for Azeroth is the fastest-selling World of Warcraft expansion ever, showing their MMORPG still wields some clout in the marketplace. After all these years, they say the game's expansion set a new one-day sales record by moving 3.4 million units:

When the Battle for Azeroth™ erupted worldwide last week, champions of the Alliance and the Horde around the globe were called upon to fight for their faction. Heroes everywhere turned out in force, and Blizzard Entertainment today announced that as of Battle for Azeroth’s first full day of launch on August 14, more than 3.4 million units of the latest World of Warcraft® expansion had sold through worldwide—setting a new day-one sales record for the franchise and making it one of the fastest-selling PC games of all-time.*

“Battle for Azeroth is a definitive chapter in the Horde and Alliance conflict at the heart of Warcraft, and it’s been thrilling to see players representing their factions in record numbers and embarking on their war campaigns—not to mention joining in ourselves,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “But the launch is just the beginning of this conflict. More epic content is coming to World of Warcraft in the weeks ahead, and we can’t wait for players to experience the full story as it unfolds over the course of the expansion.”
