Question for those who know about the Terra map type. Its about 1000AD and I have 12 cities on the homeland and I'm exploring the new world. 12 cities seems about right for a good spaceship launch. I'm aiming for early 1800s but as I'm just researching Nationalism, seems a bit optimistic, so I don't want to have to settle the New World if I don't have to, which leads me to my question.....
What are the resourse balance issues. ie, are there any resources solely found on the new world. In my map gems appears the case but I've never played on Terra before so I don't know if that's just this map.
