Developer: Chris Sawyer
Release Date: 1995

Transport Tycoon Deluxe was released in 1995, a simulation game by Chris Sawyer in his graphic/UI style about managing transportation in a city. Sort of the progenitor to things like Cities Skylines. Or maybe just the transportation parts of SimCity.

The source port OpenTTD, as its name might suggest, is a reimplementation of Transport Tycoon Deluxe. Like some other ports on this site, it is not based on existing code, it is a reimplimentation of the engine designed to consume the Transport Tycoon Deluxe data files.

For a long time, Transport Tycoon Deluxe was not commercially, so em>OpenTTD allows you to download third party clean room data implementations of the game data files. When you run the game for the first time, it will prompt you to download the files for you. There's also tons others to choose from. More recently the game was resurrected so you can get the official files from Steam or GOG as well.
