In Civilization 6: Rise and Fall, you earn points every time you fulfil your Dedication, or complete researching a new technology or civic before anyone else in the world, making it a Historic Moment for your civilisation.
The start of every new era gives you four Dedications to choose from you get to pick just one if you're in a Dark/ Normal/ Golden Age, but if you earn a Heroic Age – going from Dark to Golden Age – you get to pick three. Dedications are the main focus of a civilisation, such a constructing Districts, converting a city to your religion, discovering a new continent, or even something as simple as completing a trade route. The points needed are different for each civilisation, and depend on your position in the tech and civics tree relative to the era the game's in, the milestone Historic Moments you've achieved, and the Dedication you've chosen. Say the threshold for Golden Age is 30 when you begin then the bracket for Dark Age might be 0-15, and anywhere in between constitutes Normal Age. Ages work on a points system, with the game giving you three different tiers at the start of every new era. How you do in one era defines the benefits for the next era. One of the biggest and most obvious additions in Civilization 6: Rise and Fall is "Ages", which reflect your performance in an era, and define the peaks (Golden Age) and troughs (Dark Age) of your civilisation. Rise and Fall is quite successful in emphasising different ways of playing – an improved advisor system includes recommendations from other branches, such as science, military, and religion – but it's much less successful in rooting out the issues.
And being a Civilization expansion, it also brings a roster of new civilisations, leaders, wonders, buildings, districts, and units. Its aim, on paper, is to further push the manifesto laid down by the base game, and weed out the problems that led to game-breaking experiences. That's where the game's first expansion – Civilization 6: Rise and Fall – comes in. The big downside was the rather fickle and dumb AI, whose cluelessness in times of war led to some hilarious moments.
Civilization 6 brought some big ideas when it released in 2016 with the introduction of Districts – city improvements that occupied their own tiles instead of sitting atop the city tile, a revolutionary concept for the series – completely changing how players viewed the location of a new settlement, and new systems such as Eureka and Inspiration playing a huge role in allowing for non-domination victories.
