PostMaster is a simulation game on adapting your business to a growing city. You will start out with a single post office, supplying pick-up and delivery services for a small area of the city. To maintain an excellent service you'll need to hire workers to sort mail, contract security guards to protect your offices from robberies, while also purchasing new vehicles.
Once you've settled into your first office, you'll need to look to the future of your company and determine the best plan of action to expand your services. In order to maintain your claim on postal services for parts of the city, you're going to need to remain competitive. With a rival business looking to take a cut of the services there are methods of attack to remain the superior mail distribution business. You can carefully plan your delivery routes to make your average delivery time faster than anyone else, or you could lower the prices of your services to remain the cheapest.
