Battle for Azeroth is the fastest-selling WoW expansion ever

World of Warcraft's major expansion Battle for Azeroth had its first full day of launch on August 14, and now we know that it is the fastest-selling World of Warcraft expansion to date, shifting more than 3.4 million units on that day alone, setting a new day-one sales record for the franchise at the same 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 co-founder 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."

It charted in the UK top 10 charts on its own, which is hugely successful for an expansion, but have you been getting stuck into the battle?
