FenrysWulf
Evil Norse Wolf
In all the Civilization games my strategy has always been to build only offensive units with high mobility, like mounted units and tanks. The theory being that you can defend yourself by attacking attackers before they get to you, and the quicker you get to the enemy city, the less time they have to bomb you or attack you with artillery, etc. I really don't like using a stack of slow moving infantry. This has always worked in the past games, but it's different here because of the fact that certain units are very susceptible to others, so knights against pikemen doesn't work like it used to. I have to learn a new way to make war, and it's hard to adjust.
