Easy money
During the second part of the game (ruling as the king), if you want to earn more money without making evil rulings, buy out land from Albion during or before the last mission on the to-do list of every day. This will grant you money over time, and help you lower the Civilian Casualties before the final battle of the game. Note: Although long, this process is effective and does not progress the time remaining until the final battle.
After you become King or Queen, buy yourself a house or sleep at the castle until midnight. Preferably, purchase a house next to the Tattoo store at Bowerstone Market. Sleeping until midnight about 12 a.m. is the best. Run over to the store that sells potions and do a break in. The guards will warn you not to be in the store and that they will make an arrest. Ignore them. Because of your status you can get away with the crime. Steal all of the items in the stores. You will not want to pay for any of the items, because you need to save for the final battle (especially if you are good). Raise the rent on the houses and the stall vendors to be set to "High". For stores that are in the buildings such as the Blacksmith, set their prices to "Highest". After the potion store, run to the clothes shop, then to the Blacksmith, and over to the barber shop. Steal all their items and sell them to the pawnshop, for easy money. Do this before morning. Repeat this as many times as desired. There are no limitations.
This works best with a wired controller. At any point in the game, provided you have purchased property, go onto the Road to Rule and just remain there. Every five minutes, you will earn your rent/shop profits and there will be no risk of attack. This works best when you own shops, as properties will deteriorate over time unit you earn nothing, but shop profits do not diminish.
