OpenTTD is an open-source remake of Transport Tycoon Deluxe. It is an isometric transport business simulation and building game. Compared to the original, OpenTTD features high resolution support, modernized multiplayer capabilities, advanced signaling, support for significantly larger maps, improved terraforming and road/rail construction system, improved water transport features like canals and shiplifts, vehicle cloning, advanced orders and more.

While the game does have its own audiovisual assets, graphics and sounds/music from Transport Tycoon Deluxe can be imported from an existing installation.

Its original build was released in March 2004. While it eventually grew a large community of players as a standalone release, it was released on Steam and GOG.com in 2021 to increase visibility and potentially expand the player base.

Updates are generally released multiple times per year, with nightly builds also publicly available. The internal repository for community modifications and add-ons is well-populated and multiplayer servers are plentiful.
