The World Congress is also making a comeback, along with the diplomatic victory condition. The World Congress and Diplomatic Victory return Many other civs, as well as governors from Rise and Fall, have been rebalanced or retooled to take advantage of the new mechanics. Enemy troops that get caught in a blizzard on Russian territory will now suffer increased attrition while you sit back and wonder why no one ever heeds the warnings about invading your country during winter. For example, Egypt’s bonuses will now reflect their unique talent for making the best of regular river flooding. Some new and existing civs will be getting unique ways to take advantage of these events. Each will provide some kind of potential reward to compensate for the risk of building in a danger zone. There will also be blizzards, storms, droughts, and coastal floods to deal with. Volcanoes can erupt and scorch adjacent land, but also create similarly rich deposits. All rivers on the map will now flood semi-randomly, potentially damaging constructions on their banks but leaving behind fertile soil that will increase agricultural yields. Long before you have to start worrying about carbon emissions and rising sea levels, however, the map is going to throw some other reminders of nature’s fury your way. Natural disasters bring risks and rewards There are three phases of sea level rise that can play out gradually as carbon emissions increase, meaning you’ll have time to take steps to prevent things from getting worse once climate change is in motion. But eventually, they can become permanently submerged, including the loss of any non-city-center districts they contain. The initial stages will simply cause coastal tiles to become temporarily flooded, damaging anything built on them and preventing construction. While you can’t outright lose city centers from sea level change, they can be put in “a world of hurt,” as franchise lead designer Ed Beach put it. The severity of other semi-randomized disasters like blizzards and floods (more on that below) will increase as well. Left unchecked, it will eventually lead to melting ice caps and rising sea levels. Buildings and districts that use coal and oil for power increase carbon levels, and removing forest and rainforest tiles can speed up this effect. This won’t be a major factor until around the industrial age, when the first factories start popping up.

The most intriguing new feature is a dynamic climate system that will track the amount of carbon that has been added to the atmosphere by all civs on a map. Climate change will shake up the late gameĪll rivers will now flood semi-randomly, potentially damaging constructions on their banks but leaving behind fertile soil.
