OpenTTD is a simulation game for transportation and a clone of the proprietary game Transport Tycoon Deluxe ("TTD"). The game's source code is licensed under the terms of the GNU General Public License version 2.0.[4] Proprietary data files from the original TTD are not required to play the binary packed game. The game project has free/libre media files. There are official libre data sets for the graphics (OpenGFX), sounds (OpenSFX) and music (OpenMSX). Some GNU/Linux distributions already have packages for these, but if not, these can be downloaded and installed in-game from the extensions menu.[5]

OpenTTD has many improvements over its inspiration, TTD, such as larger maps and online multiplayer play. It was written in the C++ programming language using the SDL or Allegro library.[6][7]

Development[edit]

Branches of OpenTTD releases are divided up into nightly, testing, and stable releases.

History[edit]

OpenTTD originated with Ludvig "Ludde" Strigeus when he started reverse engineering TTD in 2003. Eventually, the project bears fruit in 2004.[8]

In October 2008 a graphics replacement set was released that uses the same license as the original game engine recreation project.[9] That lead to the inclusion into Linux distributions like Fedora.[10]

Version 1.0.0 was released in April 2010.[11]

The official sound set of OpenTTD, OpenSFX, was meant to be a libre sound set for the game actually was under a non-libre license for a very long time, way past the OpenTTD 1.0.0 release.[12] The sounds were licensed under Creative Commons Sampling Plus 1.0, a retired[13] non-free license (it has a non-commercial clause). So efforts have been made to completely rework the sound set to be 100% libre. Version 1.0.0 of OpenSFX, the first actually libre version, was released in March 12, 2021 without any big announcement.[14] The sounds in OpenSFX are licensed CC BY-SA 3.0 from that point on.[15]
