From the developer:
OpenTTD is an open source simulation game based upon the popular Microprose game "Transport Tycoon Deluxe", written by Chris Sawyer. It attempts to mimic the original game as closely as possible while extending it with new features. As president of a start-up transportation company in 1950, you have a choice of building rail, road, air and maritime transportation routes to build up your transportation empire.
You may want to check out more software for Mac, such as Clone Window, Finder Window Manager or Window Tiles, which might be similar to OpenTTD (64-bit for Windows Vista/7/8/10).
