Lemuria

Lemuria, an ancient city running on the now forgotten time control technology. Using the force from the stars, channeled through the star altar, they could control time and transform the versatile resource Materia into anything they wished.

You are one of the city builders of Lemuria, and you must fight for control of the altar, sometimes cooperate with others, and use your resources to further develop the ancient city. And the time limit is just one year.
