This page is a comprehensive list of improvements to your land which increases your gold per acre. The wording is from screen captures of the relevant improvements. This is the intended format:
- What the improvement "gives" you
- The way that the game describes the improvement(Price depends on amount of acres owned, so just put ??? gold)
- The name of the "offer" you get on the next turn announcing you bought the improvement
Putting in screenshots of the HUD would also work.
