Whatever hours you see that I have on steam by the time you read this is a fraction of the time I've spent in this game. I owned it back when it was new. I bought crossfire. The mind worms have long since captured me. I am one with planet now. Join me. (Seriously - this is one of the best 4X games out there. Period.)

Favourite game of all times. Perfect fusion of diametrically opposite world philosophies tumbled together on a new, hostile planet. No other game will touch Your soul as this one, besides Deus Ex, but even that pales in comparison. I'm surprised steam updated the ini file. The only difference between this and gog's version is the recent implemention of a mod (personal preference). Linux wise (Debian 12 xfce), the sound problem is still persistent, but everything else works out of the box (fullscreen, no missing cursor, no intro video cut off, no save & reload after every secret project playing). I take it the steam version would work flawlessly on w10, because gog one does. It's time for planet busters and nerve stapling:) "In one moment, Earth; in the next, Heaven."; "The wicked have told me of things that delight them, but not such things as your law has to tell."- St. Augustine We must dissent)) P.S. Don't forget to read the prologue to the story + the trilogy (pdfs were available on archive), it's fun EDIT: regarding Windows 11, theres a problem when firing up the Alien Crossfire. As of sept 2025., there are only two ways of having it fixed. You can either download a mod or patch the exe file (terranx) via the little program made by a youtuber Nathan Baggs (adamite on github). If you choose the latter, an additional exe file will popup, terranx_nb.

This is the original Sid Meier's Alpha Centauri, with updated graphics and support for modern PCs. In my opinion, SMAC is a cornerstone of 4x games and it is a genre-defining experience, even more so than Civilization. The factions are all unique and differentiate themselves very well, and the Secret Projects and Research have extremely memorable quotes. The only negative thing I have to say about this game is that the Alien Crossfire expansion, which is included with this purchase, does not work as of the latest patch.

The best Sid Meier's game by a long shot, long overdue for a remake

It's 2025 and this game is still a 10/10. While I have yet to afford Civ VII, in my opinion: this Sid Meiers turn based game is better than any of the modern Civ games that came after it. Every time I play a Civ game, I get the itch to play Alpha Centauri. Returning players and new players should keep in mind that this game was released in 1999. It doesn't handle some things as gracefully as you have come to expect from other Civ games. But it does not fall short of in-game content, extensive research, unit design, economics, projects and rich story telling - if you care to watch the FMV's and read the various excerpts. There is no other game like this. Calling it Civ in space would be a dishonest description. You play Civ on Alpha Centauri with the last remaining survivors of Earth - not past leaders. Man had taken itself to the brink and sent people into the stars to start again. The planet, Alpha Centauri, is Earth-like but along with the threat of the other factions, the planet itself holds sentient life that will spontaneously attack you. There is also another threat: Global Warming. The expansion pack, sadly, does not expand the original game; as we have become accustomed to, and is basically the same game but with 7 different factions. It's hard to gauge what a new player would feel about the expansion. For any die hard's, the original 7 factions are the best but overall the new 7 factions are fun to play and offer a different rhthym to playing. Tutorials are short and sweet while telling you what you need to know. The index is extensive and detailed. For any questions just push the menu button and give it a look through. Even changing how turns, notifications and combat is handled. 10/10. So grateful this was available on Steam for me to enjoy again.
