OpenTTD is a business simulation game in which players try to earn money by transporting passengers, minerals and goods via road, rail, water and air. It is an open-source[5] remake and expansion of the 1995 Chris Sawyer video game Transport Tycoon Deluxe.

OpenTTD duplicates most features of Transport Tycoon Deluxe and has many additions, including a range of map sizes, support for many languages, custom (user-made) artificial intelligence (AI), downloadable customisations, ports for several widely used operating systems, and a more user-friendly interface.[6][7] OpenTTD also supports local area network (LAN) and Internet multiplayer, co-operative and competitive, for up to 255 players.

OpenTTD is free and open-source software licensed under the GNU GPL-2-0-only[8] and is under ongoing development. According to a study of the 61,154 open-source projects on SourceForge in the period between 1999 and 2005, OpenTTD ranked as the 8th most active open-source project to receive patches and contributions.[9] In 2004, development moved to their own server.[10] Since 2018, the project uses GitHub for its source repository and bug tracker.[10] Starting from April 1, 2021, the game is now also available on Steam.[11]
