Sid Meier's Alpha Centauri Complete Edition Compatible OS: Windows XP/Me/98 Japanese Version I purchased this a long time ago. Everything in the photos is included. I confirmed that it could be installed on my current laptop (Windows 11 Pro), but the game would not launch. It is likely that you will not be able to play the game unless you have a PC with a compatible OS. Please consider purchasing only if you understand the above.
