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.[3]

At this time (December, 2010), proprietary data files from the original TTD are not required to play the binary packed game. Nightly/trunk build contains free media files. [4]

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.[5][6]


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


OpenTTD originated with Ludvig "Ludde" Strigeus when he started reverse engineering TTD in 2003. Eventually, the project bears fruit in 2004.[7]
