Age of Empires 2
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.
When you are allies with others, do not build a market
to avoid giving them resources.
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.

Play in deathmatch mode and choose the Vikings. Instead of
having Berserkers, they will have Barbarians.
