From the developer:
OpenTTD is a clone of the Microprose game "Transport Tycoon Deluxe", a popular game originally written by Chris Sawyer. It attempts to mimic the original game as closely as possible while extending it with new features.
OpenTTD is modeled after the original Transport Tycoon game by Chris Sawyer and enhances the game experience dramatically. Many features were inspired by TTDPatch while others are original.
You may want to check out more Mac applications, such as FlightGear, IMVU or Algodoo, which might be similar to OpenTTD.
