Resources

Resources are currencies or assets used to build, defend, and expand your nation.

Money
Money is the most important resource in Reign. Most structures, most units, and land are able to be built/purchased with money, the few exceptions are purchased with uranium (see below). Money is also the common currency on the world market. Money is gained by taxing citizens within towns and cities.

Metal
Metal is a valuable resource for unit construction. All armored and air units requires metal to build. Metal is collectable by constructing a Metal Mine.

Oil
Oil is essential when a nation wishes to attack. Almost every armored and air unit (with the exception of Mirage Jets) require oil to operate (Only in attacks, not in transferring). Oil is produced by Oil Rigs, whose output is doubled by an Oil Refinery.

Uranium
Uranium is the currency used on the Black Market, which will exchange money or units for your uranium. In fact, the Black Market is the only place in Reign in which you will be able to hire Mercenaries, Mirage Jets, and Radicals. Uranium is available for collection manually from the Overview Screen every 12 hours by clicking on the Green Icon next to the Uranium logo (Reign Pro Accounts will be able to automatically extract uranium every 12 hours). 40 uranium can be used to make a Nuclear ICBM.

Land
Land is the most important asset in Reign. At the end of each round, the nation with the top three land counts in a world is awarded a gold, silver, and bronze medal respectively. Land is gained either though purchasing it, war, or Eminent Domain. You can't buy any over 65 land.

Citizens
Citizens can be gained by building barracks. They are needed to hold units. Each gives 100 citizens.

Executive Power
Executive Power is essentially your mana pool. It slowly recharges to 100 over time at a 1 Executive Power Point per 15 minutes. You can spend your executive power on Executive Orders.
