See https://en.wikipedia.org/wiki/Sid_Meier%27s_Alpha_Centauri For Game Info
Yea its a old game, but one i like, got it through gog for all the updates, etc.. works fine in win 7. in order to get it to run correctly in win 10, you may need to do the following
Part 1: Modify AlphaCentauri.Ini
Custom World=3, 1, 1, 1, 1, 1, 1,
Part 2: (dunno if needed but did it anyway)
Changed the Compability Options for The terran/terrax(sp) files for “Win 7” and run as administrator
1. Go to “Programs and Features”
-Easiest way I found was go to the “Uninstall or change a program”, and there is a “Related Settings: Programs and Features” in the upper right corner.
2. On the left side of that panel there is a “Turn Windows features on or off”
3. Scroll down the list to “Legacy Components” and check the box. Open it up and make sure that “DirectPlay” is checked.
4. Windows should automatically download something at this point. It worked after that.
I also replaced the .ini as the post above me recommended. Without that replacement the video seemed shaky and unhappy with two monitors, and with it everything seemed to run more smoothly. It did not, however, appear required.
