Transport Tycoon (TT) and Transport Tycoon Deluxe (TTD) are computer games developed by Chris Sawyer and published by MicroProse in 1994 (TT), and 1995 (TTD). The games are economic simulations, presented in an isometric view in 2D with 8-bit graphic by Simon Foster, in which the player is in control of a transport company, and can compete against rival companies to make as much profit as possible by transporting passengers and various goods by road, rail, sea or by air. The deluxe version, as its name implies, is an expanded and improved version of the original game.

To start building a transport empire, the player must construct transport routes, consisting of stations near industries or towns, and in the case of trains or road vehicles, physical routes. One transport route can utilize several different forms of transport, e.g. truck��ship��train. The player's company and the individual stations each have ratings that depend largely on the efficiency of moving goods from one stations to the other. Higher ratings then attract more goods to a station. (Wikipedia)
