Loosely inspired by the Arthurian Legend, Kaku-San-Sei Million Arthur takes place in Britain where you play as Arthur and defend the country from invaders. The game was first released for smartphones and a few months ago it was ported to PlayStation Vita with extra features like voice acting.
With over five million players worldwide, Kaku-San-Sei Million Arthur was one Square Enix’s recent successes and that means Million Arthur is now a franchise. Square Enix just announced a spin-off Yui-Itsu-Sei Million Arthur is based on the same the universe, but this time King Arthur has four beautiful knights with him. Famitsu calls the spinoff a "harem RPG."
Here’s Arthur and Acerola from Yui-Itsu-Sei Million Arthur.
The Kaku-San-Sei Million Arthur team and Kazuma Kamachi, creator of A Certain Magical Index, are working on the game’s story. Yui-Itsu-Sei Million Arthur will be released at the end of July for iPhone, Android and other mobile phones.
