Sid Meier’s Civilization 6, the latest entry in Firaxis Games’ long-running series of turn-based strategy games, is now available on iPad. This version appears to be a port of the full PC game — with a $60 price tag to match.

2K Games originally launched Civilization 6 on Mac and Windows PC in October 2016, and released a Linux version in February 2017. The iPad version represents the first time a mainline Civilization title has been available on mobile devices.
