Description taken from PC version of this game

Transport Tycoon puts you in a multi-layered, complex, vast domain where your survival depends on wits, tenacity and management skills. You'll build or lose your fortune depending on how well you compete in a cutthroat world that revolves around building and controlling a mega-transportation empire. Your business strategies will be tested and challenged by ruthless rivals as you build or buy stations, airports, roads and shipping networks that take advantage of air, sea and land routes. Operations will be hindered by natural disasters, equipment malfunctions, stubborn council members and ferocious competitors. Acquiring and investing resources in land and equipment, upgrading your transportation systems and vehicles (land, sea and air) as advancements in technology are realized, and developing efficient systems to transport passengers, mail and goods will be formidable tasks.

A huge game world rendered with 3D landscapes and an isometric viewpoint, Transport Tycoon is a challenging resource management business simulation. Establishing and maintaining every aspect of a mega-business is an engrossing time-consuming prospect and Transport Tycoon is no exception. As a hands-on manager, you are given multiple options to customize gameplay to your liking, including five different currencies, four levels of difficulty, and a random world generator. ~ Michael L.
