Hints

In Old World you will explore the map with Scouts, expand your Nation by founding Cities on City Sites, exploit Harvestable Resources and Luxuries, and recruit armies to exterminate rival Nations and Tribes (or negotiate and trade with them). When starting a new game the map is yet unexplored, awaiting discovery.

As a rule of thumb, it is best to have at least one Worker per City, a few extras to build Roads or assist where needed and at least one to cut down trees each turn until a Lumbermill is built.

Scouts can hide in trees in friendly or enemy territory, preventing the enemy from seeing them. They can hide in all tiles if the Nation Leader has the Schemer archerype. Owned units that are hidden will display the icon above them.

After a War ends the two Nations cannot be at war again for 5 turns.

Religion

Each Nation will follow a unique Pagan Religion at first. When certain requirements are met the Nation can found a different Religion which can use Disciplines.

Each character will follow its own Religion. When enough characters in a Family convert to the Nation's religion the Nation will receive additional benefits.

Religion	Founding requirements
Christianity	Metaphysics 12 Citizens 1 Owned Jewish City 2 Global Jewish Cities
Judaism	Labor Force 2 Ranchers
Manichaeism	Monasticism 2 Global Christian Cities 2 Global Zoroastrian Cities
Zoroastrianism	2 Acolytes

Trees

Trees can be cut by a Worker to produce Wood. Trees cut down will regrow in a few turns. But if a tile is cleared completely of trees they will not grow again.
