Since launch, the Humble Indie Bundle has expanded its mission considerably, releasing everything from music to novels on a pay-what-you-want basis. Its latest bundle, though, is laser-focused on one man: game designer Sid Meier. The Humble Sid Meier Bundle includes the complete edition of Civilization III and Civilization IV, as well as 2013 tactical dogfighting game Sid Meiers Ace Patrol, followup Ace Patrol: Pacific Skies, and 2006 business sim Sid Meiers Railroads.
