From Impressions Games:
Attracting a hero to your city to defeat a monster is just one of many goals that you may be asked to achieve as you make your way through the adventures in Zeus: Master of Olympus. An adventure may begin in the Greek wilderness, where you will be asked to establish a city from whatever scant resources the rocky landscape has to offer. Then, you may need to establish a colony on more fertile shores to ensure that your city receives the supplies it needs to sustain itself. Once the colony is established, it's back to the parent city, where you might build a sanctuary to a god of your choosing, conquer another city, or fend off a monster. A god might even ask you to undertake a quest to retrieve a mythical item, such as Hermes' Winged Sandals or the Golden Fleece. From there, who knows? Maybe you'll need to establish another colony, or maybe you'll need to continue building the parent city.
