My Life as a King takes place after the GameCube's Final Fantasy Crystal Chronicles and it is the third game in the Chronicles series. Whereas in that game the player fought to rid the world of the deadly miasma covering it, in this game a land previously lost to the miasma is recovered and ripe for rebuilding. Your purpose is to rebuild a prosperous kingdom with the magic power of architek, and along the way find out what happened to the previous king: your father.
Rather than controlling an adventurer or group of adventurers as in most Final Fantasy games, in My Life as a King you only have indirect control over such people. As king you can hire people to become adventurers, who can then choose to go on behests. Behests are essentially missions with bounties. Every day some of the adventurers will gather around the behest boards and wait for the king to tell them if they should attempt it or not. These missions will bring in the necessary resources of money and elementite, as well as knowledge of new lands and types of buildings.
To build the town, the king uses his power of architek and a limited amount of elementite to create buildings. Some will house people, and can be used to supply adventurers and money through tithes. Others will be shops adventurers will make purchases from, and at which the king can fund development of new products. Some will be schools to teach magic or skills the adventurers can learn from; also at which the king can fund new developments. Non-adventurer shops will keep the citizenry happy.
Game action is split into days. At the beginning of each day you can read logs of what the adventurers did the previous day, down to specifics of what happened in each turn of the off-screen battles they had if you wish. You then set behests, after which you are free to walk around the kingdom for the rest of the day and take pertinent actions such as creating buildings, funding research, approving adventurers for behests, or simply talking to the townspeople to keep up morale.
