I am trying to complete the mission of terraforming a square occupied by trees. I need to speed 500 coal, iron, stone. wood & 10,000 lime, in exchange for 7,500 wood.
This means I am spending 12,000 resource to gain 7,500 resource, where is the logic in that? Is it possible that someone has made a mistake in the amounts needed or awarded?
In the exchange at the market The black market exchange rate (is at max market level): 15 for 1 resource.*
If anything 1.6 resources for 1 makes a lot more sense than 15 for 1.
But you aren't exchanging resources for resources since you can never get more copper than you spend. You're exchanging resources for a space for a building.
If you need to exchange resources, do so at the market, either XX:1 or to other players for what ever will be accepted. Trading between players should give you a faster payoff than terraforming.
The purpose of turning a space into mountain or forest is to allow you to build or move a lumber, iron, or stone collection point.
Terraforming can be one of your best defenses. Mountains and forest have a movement penalty. They will slow an enemy down, and give your ranged soldiers time to shoot at them. They also slow you down.**
