Final Fantasy Crystal Chronicles: My Life as a King is a video game developed for the WiiWare service of the Wii console. Square Enix decided to make a game for the service that would be high profile, and it was decided that the game would be a simulation game and, later in development, a Final Fantasy title. The game is a city-building game set in the world of the action RPG Final Fantasy Crystal Chronicles and is the third title in the Final Fantasy Crystal Chronicles series. Following the events of the first Crystal Chronicles game, the son of a king who lost his kingdom during that game establishes a new one and sets about creating a peaceful and prosperous land.

According to legend, a deserted town now serves as the lifeless reminder of a once-powerful kingdom. The young son of a missing king reaches this land after a long journey, finding only an abandoned castle-and a magic crystal. Though tarnished by years of neglect, the crystal has maintained its luminous glow and bestows upon the boy the power of architek, the ability to manifest memories into reality. With the help of his loyal servants and courageous adventurers, the new king dutifully prepares to rebuild his people's homeland in this new realm.
