Description taken from PC version of this game

Zeus: Master of Olympus is a city-building game set in the legendary Greece of ancient mythology. Players start with an empty tract of land, full of possibility. By marking certain areas for housing, citizens will begin to move in and populate the budding village. These townsfolk are put to work to keep the village running and to aid in its expansion and improvement.

Some will trade, some will farm, some will patrol the streets, and (depending upon the kind of neighborhood they live in) some might even lounge around all day, just soaking up the culture. As the city develops, different types of workers become available offering more services to the community. Leaders of more advanced cities can even create buildings to appease an angry god or summon a great hero, like Perseus or Hercules.

Zeus was developed by Impressions Games, the same team that created other city-building games such as Pharaoh and the successful Caesar series. While the basic gameplay in Zeus is similar to those titles, the interface has been rearranged somewhat. Other, seemingly minor differences, in citizen behavior and the management of goods, may provide interesting new strategic challenges, even for accomplished veterans of the earlier games ~ T.J.
