Hearthstone Tops 50 Million Registered Players

Just in time for the Whispers of the Old Gods expansion -- or likely because of -- Blizzard announced that its free-to-play CCG, Hearthstone, has more than 50 million registered players.

During PAX East, the World of Warcraft developer revealed plans to give a variety of cards away to players, encouraging lapsed players to return and new players to sign up for the first time. The new expansion adds a creepy Cthulhu-like feel to the game -- even reskinning the in-game board.
