Here you have an typical mid-nineties economic simulation which, you guessed
it, simulates a airline company.

At the start of the game you own 100% of a stock corporation with a few
million dollars capital. With this money you buy airplanes, which differ in
statistics like range, price or room. On a world map you define routes, ticket
prices and load (passengers or commodities) and send them on the flight. The
rest is handled by the game itself and the only thing you have to do is buying
new planes, sell parts of your stock due to financial difficulties, watch your
balance sheet and handle a few random events like strikes or oil crises. Due
to the nature of the game you’ll spend all your time either on the world map
or in front of statistics.
