Firaxis has just released the new Gods & Kings expansion for Sid Meier’s Civilization V, following up on last week’s patch. The expansion features some significant rules changes and two entire new subsystems (Religion and Espionage returning from Civ4), as well as the expected new civilizations, units, buildings, etc.
If you have turned off the Civ5 intro movie, you might want to turn it on again briefly to see the expansion’s new movie. (Or just watch the WMV file directly…)
There’s a new manual for Gods & Kings that gives an overview of all the changes and additions, but it’s not installed automatically. You need to download it from your Steam product page, or directly from Steam links collected on Civilization Fanatics. When you open the new combined PDF manual, simply click on the Gods & Kings cover to jump to the expansion section on page 236.
Also on CivFanatics, a thread entitled Gods & Kings: Introductory Guide describes the new expansion features in great depth.
Both tactical and strategic AI seem improved compared to the incompetent bumbling in the base game, judging by my own experience and reports from other players. On the other hand, the generous AI bonuses on various difficulty levels seem to have remained much the same.
I’ve updated my Civilization 5 Manual Addenda with the above information, plus some relevant changes: Great General citadels now perform culture bombs; Spies reveal territory around foreign cities; naval units stack with embarked units; and Bomb Shelters reduce population loss from nuclear attacks. That’s just a fraction of the full feature list, though – please read the expansion manual and the CivFanatics guide for all the details!
