Strategy 2 - Rise of Nations
To gather the Timber resource, build woodcutter's camps near forests. The more trees near a Woodcutter's Camp, the more citizens will be able to work there (and the faster you will gather timber). Gathering timber will never "exhaust" the trees in your forests, but once a woodcutter's camp is "full" of citizens you will need to build additional woodcutter's camps near other forests in order to gather timber faster.
You cannot see Oil fields until your nation reaches the Industrial Age. Once you find Oil fields, you can build Oil Wells either on land or at sea. Build Refineries to increase Oil Well output throughout your nation.
Civic research at the Library allows you to build additional cities; this strengthens your economy and extends your national borders.
To gather the Food resource, citizens must build farms near your cities. One citizen can work on each farm. Since each city can have only five farms, you may need to build additional cities to increase your food production.
Garrisoning military units inside forts, castles, towers, and cities protects the units from damage and increases the attack value of the building. To garrison military units in a building, select the military units, left-click the Garrison button, then left-click the building. Units can also garrison inside of the kind of building that produced them (e.g., barracks, dock, siege factory). Units garrisoned in buildings are gradually healed or repaired.
Some buildings provide a special bonus when constructed. For instance, building a new market provides a one-time wealth bonus. Similarly, when the Mongols build a new stable they gain free ranged cavalry units. However, these bonuses accrue only when the new building increases the nation's all time high total of that building--so if the market (or stable, etc) replaces one which was destroyed or voluntarily razed, no bonus applies.
Move your scout into the unexplored (dark) areas of the map to reveal hidden territory. Your scout can also explore ruins to gain resource bonuses and discover rare resources such as silk, wine, and horses, which merchants from your market can claim.
Set a building's rally point on a unit to have new units go to wherever the unit is at the time they are created. New units will also try to join the target unit's control groups, if any.
Forts and Castles are strong defensive positions, which also influence national borders. They can also garrison military units, and can create generals and spies.
Adjust the speed of the game by pressing the + and - keys.
The level of Military technology you research at the Library determines your Population Limit, the maximum number of units your nation is allowed to control. If you reach your population limit, perform additional military research at the library. Military research also provides access to powerful siege and artillery units as well as better defensive fortifications.
If you would like to adjust game options and preferences, click the Menu button at the upper right corner of the Rise of Nations' screen (or press F10) and select Options. You can also adjust music, sound effects, and video settings.
Build a missile at a silo, then launch the missile by selecting the silo and right-clicking the target.
To have your selected unit Follow another friendly unit, you simply right-click on the target unit.
