Barbarians

Build faster
Continuously select the icon next to the percentage.
Explore enemy territory without being attacked
Advance to the Feudal age, build a Market, then create a Trade Cart. Use the Trade Cart to safely explore your opponent's territory. If your opponent is neutral, they will not harm the Trade Cart. Another trick is to create several Trade Carts and place them evenly across your opponent's area to see everything they are doing, without having to spend several thousand gold to research Spies/Treason.
Instant building and unit creation
During gameplay, press enter and type in aegis. this allows you to create any building or unit for the entire game instantly.
More bases advantage
To have a better chance of winning, you might want to build more than one base. Enlarge the base you start out with, making it completely fortified with at least two castles. Then, send a scout cavalry, or some other fast moving unit, to the opposite side of the map from your base. After you have checked the area and confirmed that it is safe, send a villager to build a castle at that location and fortify that base. This is very helpful if your enemy knows where one of your bases are located, especially during online play.
Save resources
When you are allies with others, do not build a market to avoid giving them resources.
Saving your villagers
Use the following trick to keep your villagers alive while hunting boars. If you are in the Castle Age, create some monks and place them near the villagers as the kill the boar. The monk will continue to replenish the villagers' health as they kill the boar.
