Note
When you build 1 of something, you only build a part of a building; each part takes 1 land. Having 1 part of a 10-part building is less than half as effective as 2 parts of a 10-part building. The closer to the completion of a building, the more efficient it becomes. For example, 10 of 10 Training Fields is 100% effective while 9 of 10 Training Fields is only 81% effective.
