If you have a little bit of spare change and a lot of free time, Amazon has quite a deal for you. The retailer's deal of the week offers both Civilization IV and Civilization V at a hefty discount. Either game can be had for a mere $9.
Developed by Firaxis Games, Civilization V reinvigorates the classic turn-based strategy genre with an astonishing new engine built from the ground-up for this flagship edition of the Civilization franchise. Players are introduced to an entirely new combat system, deeper diplomatic interactions and a cavalcade of expanded features that deliver a fully immersive experience. Players build and defend their empire on their quest to become the greatest ruler the world has ever known.
