**SPOILER: THIS IS A SMALL CHEAT FOR UNLIMITED MONEY. If you do not want this, then don't look.** Anyway, when I was adding water to my city, I decided I didn't want it. So I was using the little bulldozer to change it back to grass when I noticed that the price goes down, and eventually to negative if you click on the same spot a lot. I did this for a while, and got $50,000,000. All you need to do is: 1. Place a lot of water. 2. Using the bulldozer tool, keep tapping in the same spot until the money goes to -. 3. It goes by $10,000 for each press, so enjoy! Sorry if this isn't allowed, not sure if cheats are allowed to be posted.
