Transport Tycoon Deluxe (OpenTTD)

Game: Transport Tycoon Deluxe → (DOS, 1995)

OpenTTD: an open-source transport simulation game based on Chris Sawyer’s Transport Tycoon Deluxe that tries to mimic the original as closely as possible while extending it with new features, many inspired by TTDPatch. It allows maps up to 64 times larger and stable multiplayer for up to 255 players in 15 companies, with dedicated servers. It adds new pathfinding algorithms, mammoth and multi-headed trains, conditional orders, pre-signals and path-based signalling, canals and ship lifts, larger stations that can be joined, longer and higher bridges, building on slopes, drive-through road stops for articulated vehicles and trams, and zooming further out. It supports TTDPatch NewGRFs to change graphics and behavior, player-written AIs, and game scripts, and it downloads add-on content from inside the game. It’s translated into more than 50 languages, there are Windows, macOS, and Linux builds, and it’s also distributed for free on Steam, GOG, and the Microsoft Store. The stable release is 15.3 (April 4), and 16.0 is in testing: its beta4 came out on September 20. Its contribution guidelines forbid submitting AI-generated code.

You needNo copy is needed: it runs on OpenGFX, OpenSFX, and OpenMSX, the free graphics, sounds, and music the project publishes, and the Windows installer can download them. If you have Transport Tycoon Deluxe, for DOS or Windows, it can use its graphics and sounds (sample.cat and the trg*.grf files) and its music; the Windows installer can copy them. Plus Windows, macOS, or Linux.
