Building Your Community
Villagers play a vital role in Age of Empires II. Throughout your campaign, keep adding new villagers until you reach the scenario's population cap. When placing your Town Centers, consider how easy it will be to defend as well as what resources (farms, gold, stone) are nearby. As you gain villagers, focus their activities on food, wood and gold. For every five villagers have two looking for food, two gathering wood and one mining for gold. Vary this when you start building your castle. Villagers can idle once a task is completed. Keep an eye out for this and keep them working. Once you have several Town Centers, you can select tasks through there. Every villager attached to that center will work toward that goal. Set each Town Center to different goals and your villager micro management reduces.
Enhancing Their Homes
Upgrades improve your civilization's quality of life. Gold mining, horse collar and double bit axe upgrades are essential to building a strong economy. After building your castle, next build an archery range, stable and blacksmith. This strengthens your military allowing for many upgrades. Build a monastery. Not only can you upgrade your monks but monasteries can receive discovered Relics. These are source of continuous income and gathering and keeping all of them can be a game winner. A university also provides crucial upgrades to advance your civilization to the next age.
Choosing Your Special Forces
Although each civilization has its own unique unit, some units are very effective in large scale combat. Mass Archers, Paladins and Mass Infantry are a must. Start with rookie troops in each of these units. Choose one unit and build it your civilization's maximum before upgrading the other two units. It's always better to have one really excellent unit instead of two good ones. Choose and build other units that suit your civilization.
Conclusion
Age of Empires II: the Age of Kings combines history with an intense gaming experience. Starting campaigns focus on famous battles during world history. Building a sound infrastructure - food, wood, education and technological improvements bring more success than just rapidly building up your military.
