It's not just "all" or "nothing".
I'm talking about a war: a more realistic war.
Glest has its realistic base because develops an economic war: who hasn't mines or forest, hasn't resources to fight. And who hasn't researched knowledge, hasn't advanced ways to fight.
All war in the history is an economic war (I believe), and Glest reflects this aspect, but only with gold, stone and wood. And feed in the tech branch.
When you read battles in a book or see it on a TV movie, they are telling you only a part of the war. 100 soldiers may be the result of 1.000 population, including hundreds of mothers and wifes, children (future soldiers), and learned ancients.
I've submited Glest to young people who has seen other (non free) games, and I'm reflecting that they wish more sophistication in Glest, and more variety/flexibility in the elements in play.
