It's official: Activision Blizzard is committed to mobile gaming in a big way. The company has closed its $5.9 billion acquisition of King, making it the owner of Candy Crush Saga and giving it 310 million extra users. King will continue to operate independently, but make no mistake -- this is about filling a gap at a game publisher whose moneymakers are mostly limited to consoles and PCs. Between this, the purchase of MLG and the creation of a video studio, it's evident that Activision wants to have all the bases covered.
