World of Warcraft’s launch-week player concurrency climbed to its highest point since the 2010 launch of the Cataclysm expansion, as champions from around the world united to strike a mighty first blow against the fel invaders. But the battle has only just begun.


World of Warcraft had 11.5-12 Million players at the beginning of Cataclysm.

Looks like Legion has proved to be the expansion to bring the game back to its glory days.
