As the kingdom becomes more populated with farms and houses, there will be much more valuable merchant wagons rolling around. The value of each wagon that gets created is determined by how many houses surround the town, or crops surround the mill. More commerce means more treasure for the taking. If you kill everything and keep the kingdom in ruins, you’ll starve your own hoard! So don’t kill the goose that laid the golden egg. Of course, letting everything grow unchecked isn't always the best, either. If Taverns appear in your towns, you might want to burn them down, as they create more thieves than usual. Then again, if the tavern is in a town nearby your opponent, you might want to let it live. Another time you might want to kill crops or houses is if the town/mill is full. Burning a few crops yields instant gold, and it won't be long before the new one grows back. The fact of the matter is, being a dragon takes some thought! Happy HOARDing!
