Ideologies:

• Countries can now adjust their government type.
• Each ideology consists of two perks whose magnitude you can adjust, and a final effect that varies depending on the magnitude specified in the former.
• The ideology and the magnitude of the perks you chose will determine the political freedom in your country.
• Democracies can win the sympathy of other free countries and improve their diplomatic relationship when opposing authoritarian regimes with little political freedom, even as an aggressor.
• Optionally customise an emblem to use on your flag when you change your country's ideology. These emblems are unlocked as you earn score points or influence coins.

Rebellions:

• After taking control of a country, there is a possibility that local rebels will rise up to restore their former country.
• The risk depends on many factors, such as the GDP per capita of the region and the type of government.
• Other countries can fund rebellions through diplomatic actions, which will increase their force and the probability of uprising.
• The likelihood and strength of rebellions will fade over time as they are quelled.
• The rebellion will start in a single location and, if not quelled before too late, will quickly gain momentum and spread throughout their former territory.
• Strategically deploy troops with the defend command throughout the territories you annex to ensure that any possible rebellion is crushed in time.
• When passing through an unfriendly country there is now a risk of local militias ambushing the troops and severely damaging diplomacy with that country.

Conquest:

• Now it is mandatory to share a border or direct access by sea in order to annex any piece of land.
• Divide and conquer: new command to automatically divide your troops along the border and take large land masses more quickly.
• At the end of a conquest, any small piece of land completely surrounded will collapse and get annexed.

Economy:

• The global economy fluctuates over time, impacting the economic growth of countries around the world by shifting between booms and recessions.
• Saved money is now automatically invested to avoid devaluation and grows at the pace of the world economy, but it could also lose value in periods of economic recession.
• Bordering countries now have a greater impact on the exchange rate.
• Population growth declines when the country is overpopulated, taking into account its size and type of terrain.
• Population now migrates over time from overpopulated regions to more suitable areas within the country.
• Troop recruitment costs are higher as the size of the army increases, and slightly lower when training larger groups.
• You can now further increase your military spending to upgrade their equipment and facilities and thus enhance their capabilities. This extra spending also reduces very slightly the cost of recruiting troops both for you and your allies.
• Budget changes are now applied progressively over time.

Usability:

• Click on the name of a country in the ranking interface to select it.
• Click on the top part of the upper toolbar to select your own country.
• Click on the flag of the selected country in its overview tab to go to that country in the map.
• New defense map overlay and stat: see the combined defensive power you would face when attacking a country if all its allies intervene.
• Optionally move your capital for an additional cost by using the Urban Planning research project.

Data:

• New countries: Greenland, Northern Cyprus and Vatican City.
• Military power updated to 2023.
• Improved regional population end economy data.
• New research projects that require a constant allocation of research points that are consumed every day and grant a bonus according to the amount used.

Custom games:

• Flags, names and date can also be changed now.
• Custom multiplayer games can now be saved and loaded instantly at any point, and you can even create a new multiplayer game from any of your single-player custom saves.

Multiplayer:

• New rating system and leaderboard: analogous to influence coins but the earned amount diminishes as it increases for high values, so the determining factor is the winrate.
• Absent players are now replaced by AIs while they are offline.
• Required progress to win now decreases over time to ensure that most games wont take longer than about 2 hours.
• The minimum bid is now lower for weaker countries, and is capped for players with high influence coins, so that they can optionally play weaker countries and lower risks.
• However, players with lower influence coins will get the stronger countries when the bids are equal, so experienced players will still need to risk higher amounts of coins to play with the stronger countries.
• Weaker countries now start with more money and research points in order to bridge the gap with the stronger ones at the beginning of the game.
