Kaku-San-Sei Million Arthur was the start of a brand new series for Square Enix that grew large enough to get a live action TV show. But, Square Enix is moving on from the first game. The smartphone version will close on March 30, 2015, but players will be able to continue playing the game on other platforms.
Kaku-San-Sei Million Arthur was ported to PlayStation Vita and a Nintendo 3DS version was released just a few months ago. The Amazon app store version will also stay online. Players will be able to import their data into those versions of the game and the new smartphone game, Kairi-Sei Million Arthur. Details about what data can be transferred into those titles have not been announced.
