Your are Inca dignitaries, fighting for political supremacy in the Andes. You must exploit the new, still virgin territory of Morray, north of Cuzco, a vast region of forests and mountains, to find the new bases of your civilization.
You must irrigate the soil and plant innovative food crops in circular terraces. Build Villages, then transform them into Cities by building Temples. Then expand the Temples and organize ever grander festival in honor of the Sun God.
