I'd rather the achievements be less about conquering shit like they are in EU4. Such as...
A Real Russian Revolution - As the Soviet Union, have the greatest industrial score in the world.
Cotton Diplomacy - As the CSA, have a Great Power intervene on your side in the Civil War.
Land of the Free - As any country, attract x-amount of immigrants.
Now That's a Factory! - Have a lvl. 99 factory with a full staff (not even sure if this is possible)
Mahan's Dream - As a Great Power, have more capital ships than all the other Great Powers combined.
The Global Revolution - As a Great Power with 3 or more neighbors, have all of your neighbors and yourself be Proletarian Dictatorships.
The Invisible Hand - Maintain a profit with 0% tariffs and less than 5% taxes.
No Coal, No Problem - As a country that produces no coal, have an industrial score of over 1000.
A Militarized State - As a country with over 1 million pops, have 20% of your pops be soldiers.
Swiss Neutrality - As Switzerland, never go to war with another country (this includes being attacked by a hostile power)
Reverse Imperialism - As an uncivilized African nation, become a westernized Great Power and own a state in Europe.
Liberator - As a Great Power, liberate 5 countries through crises (through war or diplomacy).
