It's staggering to think that World of Warcraft is now six years old. Blizzard Entertainment's video game masterpiece has spent over half a decade dominating the online role-playing scene, with no sign of letting up. Nothing comes close. Player opinions of Azeroth may have waivered through the years, but critics unite in praise each time a substantial update or expansion pack adds to the already bulging install size. Whatever your thoughts on the game are, and no matter how many times you have cancelled your subscription (only to resub later), World of Warcraft is arguably the greatest MMORPG in the world.
