Fans of the venerable Civilization franchise have something extra to be thankful for today as the highlight anticipated Civilization: Beyond Earth ($37) lands on the Mac. Currently available at a special launch price on the Mac App Store, the new sci-fi themed chapter takes Civilization players to the final frontier where they must tame a new world and write the next chapter for humanity. The usual Civilization game play aspects abound here, with players challenged to explore and colonize an alien planet, choose the direction of their new culture, research new technologies, build armies, cities, and wonders, and much more.
