I'm a huge fan of these type of games. I've spent hours and hours playing Transport Tycoon, Railroad Tycoon, Industry Giant, and city builders like SimCity, Caesar, and Pharaoh. Unfortunately, it's been quite a few years since a good one has come along, so I was happy to see Post Master and gave it a try!
I tried it for several hours, and although it is addictive, the game experience doesn't change. Basically, you're doing the same thing from the beginning. Yes you can buy new offices and expand your business, but running a 2-office business is the same as running 10 offices. You open the office, select your vehicles, plan their tasks and routes, and then try to keep an eye on volume of mail being handled.
This game has a lot of room for improvement, and I truly hope the developers will delve into it further to create a more in-depth experience. It's a nice game, but I do believe this has the potential to become more than that!
-Allow to upgrade existing post offices.
-Allow to skip to end of day.
-Get a daily status report with details about income and expenses. How much money do you actually make from letters and packages? How much do you spend on maintenance, fuel, paychecks?
-Better and more detailed graphs. It is very hard to see the big picture here.
-Efficiency report for each vehicle, are they actually making money? Is the vehicle too big or too small for the actual volume of mail, or is it making too many or not enough trips to handle their cargo?
-The ability to upgrade a vehicle, to make it faster or expand the cargo space.
-Distribution centers where mail gets sorted.
And I'd love to see the game develop over time, like unlocking things, seeing the city expand, adding more elements to the game:
-Trains, airplanes and boats to deliver your mail
-Adding more different types of mail, unlocking over time, requiring to build specialty buildings and/or vehicles.
Examples: international letters and packages (in combination with trains and airplanes), magazines, advertisement, catalogs, extra heavy packages, fragile packages, and maybe even love letters, christmas cards, birthday cards, party invitations (Yes I know those are realisticly not treated as seperate mail, but I'd love to see more elements in this game)
-In-game companies that ship items using your (or the competitor's) services. For example bookstores, game stores, clothing shops. Business can expand, shrink, or even go broke depending on how their deliveries are being handled.
-A feature from Transport Tycoon: being able to donate funds to a city, so the city will expand, improve infrastructure, allow new businesses to develop etc.
And please, add a campaign or scenario maps!
