OpenCiv2 - Civilization II (Multiplayer Gold) reconstructed
https://github.com/richardpenman/civ2

You need your own copy of Civilization II Multiplayer Gold Edition.

1. Move OpenCiv2.app to Applications (or anywhere).
2. The program is not signed by a registered Apple developer: the
   first time, macOS refuses to open it. Open System Settings >
   Privacy & Security and click "Open Anyway" (or, in Terminal:
   xattr -dr com.apple.quarantine /Applications/OpenCiv2.app).
3. The first time, it finds the game where it is usually installed
   (~/Civ2, ~/Games/Civ2, or a Wine or CrossOver drive C:), or its
   CD (or a copy of it) mounted, or a disc image of the CD (a .cue
   file with its .bin, in ~/Downloads, ~/Desktop, ~ or ~/Civ2*)
   (else it asks where it is), and copies it into
   ~/Library/Application Support/OpenCiv2/GameData; then the game
   starts. Afterwards it starts the game directly.
4. The music (the CD's audio tracks) comes only from a disc image:
   found, it is encoded into GameData/Music (a few minutes).

From Terminal, OpenCiv2.app/Contents/MacOS/OpenCiv2:
  --setup [FOLDER]   set the game up again (from FOLDER: the
           installed game, the CD, or a disc image's
           .cue: with only the music missing, adds it)
  FOLDER             play the game in FOLDER where it is
