In the next civ, leaders would have the ability to create concessions of they country in foreign cities, giving the ability to put military units in that cities and to have comercial benefits in there. Of course this ability is only allowed in the modern ages, and would give benefits to both leaders involved: the one that gives the permission and the one who put their concession in the city.

What do you think of this?

Using this system you should also be able to create puppet states. Lets say you conquer a territory on another continent, but it would be so corrupt that you don't even want it. You should be able to turn it into a Civ that pays tribute to you and that you can occupy. This would allow you to turn those corrupt and useless cities on your borders into valuable and permenant allies.

Excelent idea
Also i have tought in another thing: The Vassalism
The ability that apears in the Middle Ages and permit one country to be vassal of other country. The minor country pay a tribute on the other one and give military support.

I agree. COnsidering that I would love the diplomacy mode to be expanded, this was one thing I missed the most..

Love the vassal and puppet idea.

Vassals sound just like the Surrender diplomatic option in SMAC. This would have been really powerful in Civ3 with the mega-corruption system. As it is, you kill off another civ and end up with a bunch of massively corrupt cities that do you no good and force you to spend lots of gold rush-building improvements. But if you get the other civ to surrender, you can just give them back all their cities and get permanent tribute, diplomatic aggreements, and a willing trading partner, at least until someone else conquers them. It would also make things a lot more realistic.

Although they are puppets, another civ may offer to help 'liberate' them from your imperialism. You could do the same, or fight proxy wars.

Also, you could sell your goods at ridiculous prices to them and get theirs for ridiculously low prices.

The form of government you chose should also influence how you deal with vassel states. Republics and Democracies would be more adverse to obtaining serfs.

It should also depend on the age you are in. In the ancient age vassalage should not be frowned upon as much as if it were done in the modern ages. I,m thinking of how Rome went about things even though it was a republic at the time vs a Western Democracy in this day and age.

however vassal countries could never win cities by culture neither competing with their masters by culture, because if the central power of the big country is away from there, then it will be more easier to get those cities, that wouldn't produce much shields.

i like this concept "proxy wars". it would be nice to fight little wars to gradually increase the experience of units.

What do you mean by little wars?
