fewest copies of all the games in the Civilization series. It sold more than 100,000 copies in its first two months of release. This was followed by 50,000 copies in April, May and June. In the United States, Alpha Centauri was the tenth-best-selling computer game of 1999's first half. Its sales in that country alone reached 224,939 copies by the end of 1999, and rose to 281,115 units by September 2000. Critical reaction The game showed well at the 1998 Electronic Entertainment Expo (E3). Walter Morbeck of GameSpot said that Alpha Centauri was "more than hi-tech physics and new ways to blow each other up", and that the game would feature realistic aliens. Terry Coleman of Computer Gaming World predicted that Alpha Centauri would be "another huge hit". OGR awarded it "Most Promising Strategy Game" and one of the top 25 games of E3 '98. In a vote of 27 journalists from 22 gaming magazine, Alpha Centauri won "Best Turn Based Strategy" of E3 Show Award. Aaron John Loeb, the Awards Committee Chairman, said "for those that understand the intricacies, the wonder, the glory of turn based 'culture building,' this is the game worth skipping class for." Alpha Centauri's science fiction storyline received high praise; IGN considered the game an exception to PC sci-fi cliches, and GamePro compared the plot to the works of writers Stanley Kubrick and Isaac Asimov. J.C. Herz of The New York Times suggested that the game was a marriage of SimCity and Frank Herbert's Dune. GamePros Dan Morris said "As the single-player campaign builds to its final showdown, the ramifications of the final theoretical discoveries elevate Alpha Centauri from great strategy game to science-fiction epic." Game Revolution said, "The well crafted story, admirable science-fiction world, fully realized scenario, and quality core gameplay are sure to please." Edge praised the uniqueness of expression saying it was "the same kind of old-fashioned, consensual storytelling that once drew universes out of ASCII." The in-game writing and faction leaders were also well-received for their believability, especially the voice acting. GameSpot reviewer Denny Atkin called the factions and their abilities Alpha Centauris "most impressive aspect". Greg Tito of The Escapist said, "the genius of the game is how it flawlessly blends its great writing with strategy elements." Alpha Centauri's turn-based gameplay, including the technology trees and factional warfare, was commonly compared to Civilization and Civilization II. The Adrenaline Vault's Pete
