Re: Massive Battles?
Did you put your units size to huge? If you used the huge set up you will have around 3000 men per legion if you use mercenaries the amount of men will lie slightly higher.
With the huge settings your enemies will have roughly around the 4000 men.
I read on one of the creators descriptions of the mod that there were 5,000 to 18,000 battles
You won't get this amount of men in one legion but it is possible to fight around 5000 - 18000 men in one battle this means more then one army taking part in the battle. Keep a group of 3 legions together at all times fight an enemy army and you get like roughly 12000 men in one battle.
I hope this explains it a bit how things work.
