Mayor's Tips & Tricks - Services

When starting out, I only brought coal power stations and the small water towers, it was the biggest bang for the buck. I would save up as I leveled so that I had enough money to buy the biggest fire, police and hospital. I wouldn't level up to the level they are available till I had that money in the bank. They give the greatest coverage and are worth the extra effort to get them, eventually I sold my water towers and coal plants and upgraded, but that was much later probably around level 30.
