At Blizzcon, the company’s annual event for the Blizzard fans, the company did its best to explain that Battle.net is undergoing a major overhaul. The service has 12 million members who play older games such as the original Starcraft and Diablo II on it. But it hasn’t been overhauled since 2003. That means it has to be remade for the age of social networking. The features behind the new Battle.net explain why Blizzard is taking a long time with the new game. The original Starcraft launched in 1998 and it has sold more than 11 million copies. The company has been working on a sequel for some time, but the enormous success of World of Warcraft diverted the company’s resources away from Starcraft II for a time.
