The latest Humble Bundle offers the chance to own three complete Civilizations, as if you were trying to recreate the British Empire. Along with Civs III, IV, the lowest tier contains the recent Ace Patrol games, which are fairly lightweight, but clever, replayable and oddly adorable considering the World War dogfighting subject matter. All of that, along with the latest incarnation of Railroads! can be yours for any chosen price. Pay more than the average (at time of writing, $8.16) and you’ll receive Civ V, and the Gods and Kings DLC. More than $15 unlocks the Brave New World DLC as well. BONUS: approximately two days of a Humble Paradox sale remain.
