dudalb: Just to clarify:
The Civ 2 gold game is a 32 bit game,but has a 16 bit installer. There are workarounds that are not all the hard to get it to run on a 64 bit computer.
The original Civ 2 and it's expansion discs are 16 bit programs. Short of Goint the virtual machine route, there is no way of getting them to run on a 64 bit computer.
Maxvorstadt: CIV II had expansions?
I only know the base game (still own the boxed version), but I never heard of an expansion.
There were three expansions.
First one added 20 new scenarios - it was called Conflicts in Civilization
Second one added several fantasy scenarios (X-Com, Master of Orion, Master of Magic worlds, etc.) - it was called Civ II Fantastic worlds.
Third expansion included all of the above and added multiplayer for the game.
Only the Ultimate Civilization 2 Classic Collection includes all the above features.
There was also a remake of Civilization 2 called Civilization 2: Test of Time (really loved this one).
