Transport Tycoon Deluxe

Transport Tycoon Deluxe is an expanded and improved version of the original Transport Tycoon game released in 1994 by the same developer Chris Sawyer. Deluxe, which was released in 1995, contains many significant changes over the original game, such as the addition of three new environments, an included World Editor, and even a multiplayer game mode.

Transport Tycoon Deluxe, or TTD, is a transportation/ commerce simulation game where the player must manage a company that handles all kinds of transportation from buses and trains to boats and planes, in the hopes of striking it big and making it rich. The game is known to give the player great freedom of choice with lots of clever ideas mixed in. 

TTD is among the best classic strategy games with many unique ideas and deep planning involved. Unfortunately, making it work on modern Windows OS (like Windows 10, 11, or newer) is challenging, especially for casual users and gamers. However, an open-source game called OpenTTD is available for free. OpenTTD aims to be as faithful to the original game as possible while providing many extended features, including compatibility with modern operating systems.
