Hints
From Old World Official Wiki
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.
The Terrain units more order will have an impact on how far they can move each turn. Hills, Sand, crossing a River, Scrub and Trees all add an extra movement point. Rivers and Roads within owned territory require only 2/3 of a movement point.
Unit types
There are two types of units:
- Melee units need to be adjacent to an enemy unit to attack it
Barbarians
Barbarians occupy City-States like other Tribes, but they are in a permanent state of War with all Nations.
