Since it isn’t Final Fantasy or Dragon Quest, Kaku-San-Sei Million Arthur may not be on your radar, but it’s one of Square Enix Japan’s successful new series. It’s a smartphone card battling game loosely based on the Arthurian legend with over a million users since it launched in Japan in April 2012. Square Enix also partnered with a Korean company to translate and publish Million Arthur in the region.

Million Arthur will be released for PlayStation Vita on April 11. It will be a free download and just like the smartphone version additional items will be available to purchase. While we don’t have free to play games for Vita in America, Japan already has Samurai & Dragons from Sega and Picotto Knights from GungHo Online Entertainment.
