The Civilization series heads to space, letting you colonise an alien planet.
I'm probably the least qualified person to review Civilization: Beyond Earth. By the time the Mac version was even available to play, a mere 4 weeks or so after the Windows version, everyone who had an opinion on it had already expressed it, and they all had run the gamut of "not as good as Civilization V" all the way up to "not as good as Alpha Centauri". Ordinarily I'd not even read reviews before posting my own thoughts, but in all honesty I wasn't expecting to write a review anyway.
