How much do you love Civilization? If the answer is LOTS, then the latest Humble Bundle might interest you, because it's all about Sid Meier, and there's a hefty bunch of swagalicious Civilization goodness to be had right there.
Here's what throwing down any amount of cash will net you: Sid Meier's Civilization III Complete, Sid Meier's Civilization IV: The Complete Edition, Sid Meier's Ace Patrol, Sid Meier's Ace Patrol: Pacific Skies and Sid Meier's Railroads!
But if you pay over the average (currently $6.80 / ~£4.17 at the time of writing), you'll nab yourself Civ V and the Gods and Kings DLC on the cheap too. Pay over $15 and you'll unlock Civilization V: Brave New World. Seriously, what are you waiting for? #yolo
As per usual, you can choose how to split your donation between devs, charity (this time its Action Against Hunger), and Humble Bundle themselves.
