I saw that several mods have changed the name and version of the game, I'm developing one and I wanted to know how to change it

could someone make a mod so that you do not have to go through every provence to capitulate a nation? something like a few turns after you take there capital they surrender or after you take a certain percentage of provinces.  

I feel like the game is missing something vital. Historical strength of nations. What I mean by this is that power is purely calculated by income and income by how many provinces a civ owns. By adding these starting buffs and debuffs. Here's how they would work:
Starting buffs and debuffs can be removed by decisions in events or just by time passing. Eexample: Napoleon's France could get a starting buff to soldier attack and defence so they can realistically take on a few countries in Europe easier. They start with the buff in the Napoleonic wars start date and lose it when it's 1821.

Add spies, you can send them to another country to get some information like:
Army size, How much gold they have, How much gold they earn, How much they can recruit etc.
There is a chance the spy will get caught. But, the weaker the nation, the lower the chance he gets caught. If he got caught the country might decrease relations with you.
If a country sends a spy to your country, they will get your info and see if you're weak so they can attack you. If your country is strong, they might fail and you get a message that [country] sent a spy to you, then you can decide what to do: send insult, declare war, demand other stuff etc.

It's a bit anoying to, let's say, have two French countries, that both have different nationalities. It doesent make sense that France 1 has to asimilate land from France 2. Isn't there any way to make a system like in Victoria 1/2, where every country has accepted cultures. Maybe we could have the ability to make our own cultures, and if we make new countries, we could have the option to asign them accepted cultures. The cores can stay the same, but when we make new scenarios, we could add to each province as many cultures as we think are necesary. Maybe when raising soilders, you could have the option from wich culture these soldiers should be.
That's my suggestion
