Humble Bundle is featuring some of Meier’s most popular strategy games, with the highly regarded Civilization series well represented.

As is the standard with Humble Bundle sales, this month users can pay whatever they like for Sid Meier’s Civilization 3 and 4, as well as Ace Patrol, Ace Patrol Pacific Skies and Sid Meier’s Railroads.

For those willing to pay more than the average, currently hovering between $7 and $8, they will receive Civilization 5 as well as the Gods and Kings add on content for the game.

What is unusual in this sale, however, is the addition of a $15 set price that will net users the entire package of aforementioned games, with the edition of the recently released Brave New World downloadable content for Civilization 5.

The proceeds of the sale can go to video game publishers 2K, who publish all of Meier’s games at the moment, to charity Action Against Hunger, or to the Humble Bundle web-store itself, with the ability for users to determine how their payment gets divided up amongst these three groups.

Meier’s games are well regarded amongst the strategy game community. His Civilization series, for example, sees players starting a new civilisation from scratch with limited resources and competing against other civilisations throughout history to become the most powerful in the world.

So if you’re looking for a cheap (and highly addictive) strategy game fix or want to keep your eye on future deals, head over to the Humble Bundle store now.
