TTDPatch

''Transport Tycoon'' is a business simulation game designed and programmed by Chris Sawyer, and published by MicroProse on 15 November 1994 for DOS. It is a transport business simulation game, presented in an isometric view in 2D with graphics by Simon Foster, in which the player acts as a transport company owner, who competes against rival companies to make as much profit as possible by transporting passengers and various goods by road, rail, sea and air.

''Transport Tycoon Deluxe'' is an expanded and improved version of the original game, released in 1995. A version for Android and iOS was released on 3 October 2013 based on the sequel, '' Chris Sawyer's Locomotion''. A fan-made game engine recreation ''OpenTTD'' is also available. In November 2024, Atari SA acquired the IP rights from Chris Sawyer.

Gameplay

Transport Tycoon is a business simulation game where the player takes control over a transportation company and is tasked with building out a transportation network by constructing transport routes in order to move passengers, goods and materials around an isometric map to earn money. Routes are created by building stations between two or more locations, with the available transportation options being rail, road, air and
maritime. 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 their efficiency at moving goods from one stations to the other. A station with high ratings may attract more goods.

The game begins in 1930, and ends in 2030. The player starts out by borrowing money to finance construction of transport facilities, and is charged interest until the loan is repaid. As the user plays the game and earns revenues, they have the choice of expanding service along existing routes, or expanding their transportation network. The game features a progression of technology: in any particular year of the game generally only contemporary types of technology are available. For example, railroad signals which allow more than one train to use a section of track are initially semaphores. Later, they are replaced by red and green traffic-light signals. Similarly, in the beginning there are only steam engines, but later diesel and electric engines are introduced. In the game year 1999, monorails become available. These require a separate track system from railroads. If the player remains in business until 2030, the game announces that they have won, allows them to post their name on the "hall of fame" and then continues. At this point, the year stays 2030 and never goes any higher, although the game can continue indefinitely. Playing the entire 100-year campaign takes about 40 hours. The game allows the player to save at any time, and multiple saves of a particular game at any point are possible.

Vehicles in the game must be constructed at corresponding depots, which must be connected to the road or rail networks. Towns and cities have their own road networks, but extra roads may be needed to connect them to other towns, or to various resources.

The player earns revenue by picking up resources or passengers at a certain station, and delivering them to another station where there is a demand for them. Demand is determined by the area which surrounds the station; for example stations close to towns will demand passengers. The revenues will depend on the delivery time, distance, and quantity delivered. The influence of these factors on revenue varies according to the type of goods being delivered. For example, mail will rapidly fall in value, meaning that it can only be delivered profitably over short distances, or over long distances very fast. On the other hand, coal loses value very slowly, so it can be transported in bulk over long distances whilst remaining profitable.

At times, subsidies are offered to the first company to move a particular resource from one place to another. This encourages the player to create a larger more complex transport network, rather than focusing on previously profitable routes.

The game features a system of Local Authority. Each city has a rating for every transport company based on the impact of their transport network. When the rating falls too low, the player will no longer be able to demolish buildings or construct new stations. The rating depends on, among others, the level of service and the deforestation caused by the company.

In the course of a game cities develop and expand according to various economic factors, and new industries (demand) or other resource sites (supply) may appear. Some natural resources may also eventually be exhausted and industries without adequate transport service may shut down. Also, new models of vehicles are introduced and eventually come to replace older models. At introduction such a new model will likely have improved characteristics, but may suffer from reliability issues.

Development

Having been playing ''Sid Meier's Railroad Tycoon'', '' Populous'' and ''SimCity'', Chris Sawyer began exploring ideas and prototypes for a transport simulation game as early as October 1992, using his own isometric game engine he had developed in his spare time. For Sawyer, the game, known originally as ''Chris Sawyer's Transport Game'' or ''Interactive Transport Simulation'', started off as a way to contend with the monotony of his game conversion work. It also would allow him to combine his love for open ended simulation games and trains, he began with adding them into the game world alongside other vehicles. Sawyer wanted "little vehicles all going about their business", where both playing and observing the action is enjoyable. ''Transport Tycoon'' was entirely written in x86 assembly language, Sawyer has stated that he prefers to write in a low-level programming language as oppose to a high-level programming language like C as he wants to know what every function does in complete detail and to optimise for efficiency. He claimed that working in assembly code allowed him to add more complexity to game, as it allowed him to optimize the workload on the processor better.

Over the course of development, Sawyer in addition to adding different modes of transport, he implemented various different worlds and a basic economic mechanic to earn money, one that was even more simple than the one in Railroad Tycoon. The time period was set from 1930 to 2030, as this would according to Sawyer lead to "greatest variety of train and vehicle type" and that 100 years per playthrough felt right. It would give players 30 years of steam trains followed-up by diesel and electric trains, and ending with high-tech monorails. Creating a challenging artificial intelligence was of paramount importance for Sawyer. He considered it the most challenging element to program, he would spend hours playing the game on his own figuring out the best strategies a human player would use and then building algorithms that simulate those aforementioned strategies for the opponent companies.

Jacqui Lyons, Sawyer's business agent, approached a number of video game publishers with a half-finished version of the game. Sawyer would leverage his preexisting relationship as a work-for-hire programmer with MicroProse, to convince them to take a chance on a game. Following a productive meeting with MicroProse, Sawyer agreed to sign with them to publish the game, as he found the team at MicroProse more supportive. Ultimately, they would publish the game, which included changing the name to ''Transport Tycoon'', where it would sit alongside their '' Railroad Tycoon'' franchise. When he signed the contract with MicroProse, the railroad parts were already nearly finished. Originally, a producer at MicroProse set the timetable of two years for the rest of development, but Sawyer managed to get the game in shippable state in 4-5 months, although he had to cut some content and ideas. Some of these were later included in the deluxe edition. MicroProse had very little input on the game itself, most of their suggestions were either unfeasible or ignored. On a suggestion of Sawyer, the game contains a few easter eggs referencing other MicroProse games.

By the time Sawyer had finished up his last game conversion contracts, he had created a full-fledged version of the game in low resolution with his own crudely hand-drawn graphics. He decided to spend all of his time for a couple of months on the project and see how much progress he would make. The low quality bitmaps Sawyer drew were replaced by Simon Foster, an artist he had met around that time. Foster recreated the art of the trains, trucks, buildings and scenery with high-resolution bitmaps. This was made possible by newly released graphic cards with the ability to render 8-bit graphics which allowed them to render the redone art and sound. Within several months the game was almost hundred percent complete and would be shown to MicroProse.

Music

The music in ''Transport Tycoon'' are original compositions by John Broomhall. It features old-style blues and jazz tunes including parts of Herbie Hancock's Cantaloupe Island.

Reception

A reviewer for ''Next Generation'' gave the DOS version four out of five stars, commenting, "The best economic sim since ''Civilization'', Microprose's new ''Transport Tycoon'' has all the features of Sid Meier's '' Railroad Tycoon'' mixed with the look and ease of Maxis' ''SimCity 2000'' and a host of new features ... that give the game a feel that is all its own." He further lauded the game for its graphics, "pleasant" music, sound effects, addictive play, and realistic simulation of the growth of cities and towns.

''Next Generation'' reviewed the ''Transport Tycoon Scenario'', rating it three stars out of five, and stated that "A solid upgrade for a great game."

Related titles

A "World Editor" expansion pack was also released for the original ''Transport Tycoon'', but was overshadowed by the Deluxe version released shortly afterward. It featured an alternative, Martian set of graphics, which did ''not'' appear in TTD.

''Transport Tycoon Deluxe''

''Transport Tycoon Deluxe'' is an expanded and improved version of the original game. It included many significant changes, such as:

* 3 new gameplay environments alongside the original Temperate climate. These are: Tropical, Arctic, and Toyland. The new environments introduced different industries and challenges. For example, towns in the Arctic environment do not grow without regular deliveries of food, while those in the Tropical environment require access to fresh water before they will grow.
* World Editor included - Allowing the creation of custom maps and scenarios.
* Network play, allowing multiplayer games.
* Improved railway signals. The original ''Transport Tycoon'' only included ''bi-directional signals'', permitting trains to pass in either direction, while the Deluxe version introduced ''uni-directional signals'', to restrict trains to a single direction of travel. This has significant effects on gameplay, as the original bi-directional signals could result in trains trying to travel towards each other on the same section of track. While this would not result in crashes on a properly signalled route, it did require either building extra track, to allow the trains to pass each other, or building a great many tracks in parallel, to avoid the problem. The new uni-directional signals enabled building one-way track systems, giving the player greater control over the operation of their rail network, enabling far more efficient routes, and preventing trains from trying to travel the "wrong way" on a section of track. By utilising both uni- and bi-directional signals, the player could now build effective switching yards, junctions, and other useful designs. It also enabled the building of continental-length railroad systems, by incorporating one-way tracks in both directions, as well as the option to merge other rails with the main line. This became a very popular strategy, allowing for transportation across entire game maps, resulting in larger profits.
* Maglev trains and track.
* Buy/Sell Shares and take-over rival companies.
* Heliports.
* Ability to re-fit aircraft and ships to carry alternative cargo types.
* Games now begin in 1950 and end in 2050, while the original game covers 1930 to 2030. Accordingly, the Deluxe version loses many of the earlier vehicles from the original game, while adding several new types later on. Moreover, the vehicle names in the original game were based on real-life models, but were replaced with fictional ones in ''Transport Tycoon Deluxe'', due to trademark issues.
* The Deluxe version also allowed players to rename their vehicles, stations and towns in-game; this can be useful for identifying services in a network and adding a personal touch.
* Remixed music theme for the main menu.

''Chris Sawyer's Locomotion''

After the success of ''Transport Tycoon Deluxe'', Chris Sawyer turned his attention towards a sequel, but during development he changed his mind and produced ''RollerCoaster Tycoon'', which turned out to be a runaway hit. After ''RollerCoaster Tycoon 2'' was done, work on the third version was left to another development team, and Sawyer returned to work on a ''Transport Tycoon'' sequel, '' Chris Sawyer's Locomotion''. It was released in September 2004 and was described by Sawyer as the "spiritual successor to ''Transport Tycoon''".

It received poor reviews and was deemed a commercial failure on release, but sales through the digital releases are unknown. Regardless, there is an active ''Locomotion'' community that continues to produce modifications.

iOS and Android version

On 15 July 2013, Sawyer's 31X Ltd and Origin8 Technologies announced that they were working on a mobile version of Transport Tycoon. Sawyer was originally focusing on funding for the game, but ended up overseeing the design and helped with the debugging. The game was released for iOS and Android on 3 October 2013. The game is single player and is primarily based on '' Chris Sawyer's Locomotion''.

Third-party creations

Several development teams are currently working to improve ''Transport Tycoon''. ''TTDPatch'' provides gameplay enhancements and numerous bugfixes to ''TTD'' by patching the original binary.

''OpenTTD'' is an open source complete recreation of ''Transport Tycoon Deluxe'', achieved by reverse engineering the original game.The 50 Best Free Games On PC - 8. Open Transport Tycoon
on Rock, Paper, Shotgun (31 October 2016)The 50 best strategy games on PC - 50: Transport Tycoon Deluxe (1994)
on Rock, Paper, Shotgun by Adam Smith ''"Where can I buy it: OpenTTD is a free, open source remake."'' (18 November 2016) It delivers many bug fixes and general enhancements to the game, like making it possible to run ''TTD'' on multiple platforms, including Mac, Linux, PSP, and Android. While both games allow new graphic sets for vehicles and terrain to be used, at present, ''TTDPatch'' still requires the original ''TTD'' graphics, sounds, binary and music files to run. While ''OpenTTD'' can still use the original ''TTD'' graphics and sounds, it does not need any of the ''TTD'' files to run as it has free graphics and sounds.
