Gods and Kings adds 3 new scenarios to Civilization 5. The scenario is in particular interesting: A steam punk scenario that takes you into an alternative reality. But let's talk about the scenarios in their order.

Fall of Rome

Play as either Eastern Rome or Western Rome trying to fend off the barbarians OR as one of the barbarians themselves. (Webhallen, Official) Both Eastern and Western Rome have to pick Social Politics, that have negative effects. This is supposed to reflect the political decay and decadence. The Social Politics make also the Barbarians stronger to make the struggle for survival harder.

Into the Renaissance

Grow your medieval kingdom into one of the great nations of Renaissance Europe, fending off outside invasions from Mongols and Ottoman Turks and fighting the religious wars of the Crusades and Reformation! (Webhallen, Official) This scenario mainly focuses on spreading religion under leadership of a major European empire.

Empires of the Smoky Skies

Build flying airships and huge tractor-like tanks from the unique tech tree of this Victorian science-fiction scenario, and use them to spread your empire across the pre-industrial world. (Webhallen, Official)

Empires of the Smoky Skies is a scenario in a Victorian science fiction style, also known as Steam Punk. Empires of the Smoky Skies plays on random maps and alters the tech tree, heavily. The tech tree projects into an alternative present and future, right from Steam Power. All technologies up to Steam Power are given to the player. The alternative technologies group into three alternative eras: The Steam Era, the Aviation Era, and the Future. Empires of the Smoky Skies features new units, buildings, technologies, and resources like Luborium and Aetherium that makes things fly and help you to dominate the world. To dominate the world, you start with 3 settlers, 2 Scouts, and 2 Land Ironclads, which will help you against the Barbarians

How to win the Empires of the Smokey Skies

To win in Empires of the Smoky Skies, you have to be awarded by the League of Empires three of five Honorable Titles and hold them for five consecutive turns. The titles are unlocked by certain technologies and are in the following domains:

Who leads the Empires of the Smokey Skies

Empires of the Smoky Skies has five unique fractions, that struggle for domination of the world. The fraction leaders "all deliver their veiled and not-so-veiled threats in a decidedly Victorian tone [as text-only messages]. The text-only messages appear under canvas paintings of the world leaders, mustachioed or with goggles. (The Verge) These paintings and text only style is in contrast to the animated and speaking leaders of the standard game. But it shows modders how to not only add new civilization with limited resources, but also how to add new win condition, and how to turn of religion, which was just added on Civilization 5 by Gods and Kings. Here is the list of the five Empires of the Smokey Skies fractions:
