2K Games has a lot of love for Sid Meier and they're proving it through a new collaboration with Humble Bundle. The latest Humble Bundle will collect some of Meier's best games, including the recently-released Sid Meier's Ace Patrol. But if you're feeling particularly charitable, you can also come away with Sid Meier's Civilization V and both the Gods and Kings and Brave New World expansions.
Humble Bundle patrons can pay what they want for Sid Meier's Civilization III Complete, Sid Meier's Civilization IV Complete, Sid Meier's Ace Patrol, Sid Meier's Ace Patrol: Pacific Skies, and Sid Meier's Railroads. Paying more than the average will also get you Civilization V and the Gods and Kings expansion, while Brave New World will only go to the generous folks that toss in at least $15.
All of these Sid Meier's games come with Sid Meier's Steam codes for PC, and a few are playable on Sid Meier's Mac too.
