Civilization V is available now for the PC. This page is a compendium of
information on the elements and mechanics of the game, assembled from screenshots, gameplay videos and
online previews.

About the Analyst
This site was set up to track pre-release information about Civilization V. Why did I do this? Because I'm not sane -- I enjoy playing "intelligence analyst" trying to parse data out of screenshots and assembling a coherent picture of the game. And because prior to just a few days before release, the information wasn't available anywhere else.
Pardon the messy, temporary nature of the pages. They are large and image-heavy. I knew when I started it that this site only had a projected lifespan of about two months (until the game was released and the information here became irrelevant), so I knew I would never be able to make everything as tidy as I would like.

9 April 2013: The official Civ V Facebook page has a teaser post all but confirming Shaka Zulu as the fourth new leader.
7 April 2013: It was brought to my attention that Gods & Kings included a number of unused Civil War unit graphics; it seems very likely that these will be used in the War Between the States scenario in Brave New World, so I have added images of them to the New Units section. The screenshots are from FramedArchitect's Civil War mod, which uses these unit graphics.
23 March 2013: Firaxis ran a Brave New World demo at PAX East today. Assyria and Brazil joined Poland as the confirmed new civilizations, and there was an overview of the new Culture and Trade systems.
15 March 2013: 2K Games has announced Civilization V: Brave New World, the second expansion for the strategy game. I will track details as they become available on this page.
19 June 2012: Gods & Kings is now available on Steam in North America. I will update the page to reflect the released state of the game as time permits, but for the most part my work here is done. Happy playing!
18 June 2012: Gods & Kings domestic release is tomorrow, but for those who can't wait, check out the G&K version of the PDF manual. You'll need to scroll about 3/4 of the way down to see the new G&K information. I will update the G&K page as time permits to reflect the changes.
13 June 2012: A new trailer video is now available. I don't know if this was the video that was playing in the booth at E3, or if it's new, but it does have new information in it. Check the Change Log for a list of updates.
7 June 2012: Several people have asked, but there has been no new G&K information out of E3.
5 June 2012: A beta patch for "vanilla" Civilization V is available (see this post for instructions on how to get it). It has a few new UI features, and a few minor things from Gods & Kings (for example, it uses the new G&K version of the Trading Post graphic).
