Ismus- I disagree, the earlier ones have a pretty low yield but later on the profits will be pretty big. It's worth it even though you have to pay a large amount of money for them.
Why do I lose so many troops while attacking other countries? I lost troops equal to about 5x the amount of that country's army size even though my power was about 150x greater and the size of my army 50x greater
Bigger army, less training. Throw the peasants out front in rags to shield the good troops. etc. Thanks for playing.
