One of the biggest Japan-related tech stories from 2012 was the success of Cygames’ social card battle game Rage of Bahamut on DeNA’s Mobage network. Whether or not Japanese social games can succeed in markets abroad is a very interesting question, and Bahamut so far is perhaps the most convincing evidence to date that they can. With over 10 million users around the world, Rage of Bahamut has been an unexpected success, and a fixture atop the iOS and Android top grossing charts for the majority of 2012.
