Back in February, Activision shared an impressive sales milestone — a cool 15 million — for Blizzard’s epic dungeon crawler, Diablo III. Jump to today, just six months later, and that number has surpassed 20 million across all platforms. That’s an impressive number for any franchise, and it’s only going to continue to grow with the imminent release of the Ultimate Evil Edition on PS3, PS4, Xbox 360 and Xbox One, which is slated to arrive on August 19.
