StarCraft II: Legacy of the Void launched on November 10 and it appears to have been a success for Blizzard, which announced that over one million players had "warped in" as of Friday, November 13.

In comparison, StarCraft II: Heart of the Swarm sold through approximately 1.1 million copies worldwide in its first two days on sale, whilst Wings of Liberty managed 1.5 million in its first 48 hours.
