Civilization 6 was recently released on iPad, which came as something of a surprise. Publisher Aspyr Media had made no previous announcements. This is not some lite version of Civ stripped down for touch-screen, mobile implementation. It’s the whole game. It’s the first time a full Civ game has been released on mobile, though previously we’ve seen arcadey versions like the underwhelming Civilization Revolution.

When it arrived on PC last year, I reviewed Civilization 6 and was generally impressed. It's a useful evolution of the empire-building series, engaging geography as a major factor in societal progress while honing systems like combat, science and culture.
