Resources - Rise of Nations
Rise of Nations - Rare Resources
Every map is scattered with rare resources, usually numbering around the two dozen mark. Any nation can collect them - even in enemy territory. Build a Merchant at the Market and dispatch him to the site of the rare resource; he'll set up shop and you control the resource as long as he's alive. Multiple nations can collect the same resource at the same time.
Rare Resources can help you in a variety of ways, from raising your population cap and improving the healing of military units to cutting your costs on the homefront. Units, upgrades, and technologies all cost resources and take time to obtain; rare resources can ease the burden.
