Villager Recruit is a Strategy and is very, very, cheap.
Game Description: Persuades Vill. to fight in army
Extra Info: While you are marching an army, you will recieve some 50-100 troops every turn. The Villagers will come more often if you are marching Swordsmen as they only need to bring are swords (and food for themselves), and will come less if you are using Spears, Pikes, Bows, Horses, etc as they are harder to make. They occasionaly some with gold.
Note that the food they bring are only worth 90 day's worth. They will also come in lesser numbers if an enemy is near.
