The Iain Banks novel Complicity dedicates a fair few words to the system requirements of Despot, a fictional game which is basically Civilization (Banks had a bit of a Civ problem). If even Iain Banks didn’t shy away from such responsibility, I hardly can.
With Civilization VI [official site] now less than a month away from launch, the system requirements are now finalised. As you’d expect, they’re not too strict, running on most PCs from the past four years or so.
