SimCity Classic is a 16-bit remake of the original SimCity. It was released in 1993 for Windows, Mac, DOS, and OS/2. A version that could be played for free was able to be cloud streamed on SimCity 4's and SimCity 3000's official website until 2012, when both websites ended their service, and successor sites did not continue to make the game available.
