Victoria is a GAME based upon a period of history. This is it's great strength and weakness.
We want to see history changed, France win in 1870, Mexico beat USA, Russia colonise the Pacific, whatever is our particular fantasy.
Trouble is once one thing changes so does all that follows. All that one can do is to ensure that your basic mechanics are reasonably historical. Breech loaders, Ironclads, Railways etc appear within in say + or - 10 years of when they actually happened. The mechanics of colonisation should mirror history in how it happened, the fun is that it should not be restricted to who actually did it. If Bavaria wants Ironclads OK, if the Papal States want an African colony OK. What should not happen is a breaking of the realities of C19th technology and politics. And one fact is that there were perceived ways that the "Family of Nations" behaved and how they saw themselves in the eyes of the world, and the nature of alliances and relationships that existed.
Claimed colonies of civilised nations could not be targets of attack for another nation without a general war between them and their allies. Attacking and seizing land from uncivillised nations was acceptable, especially if they had no friends.
The Spanish -American war is touted as being a colonial war it wasn't, it was a war between Spain and the USA it was just fought in the colonies, America got what she wanted because Spain's "war exhaustion" was such she could not hope to win, and American victory did not upset the perceived European balance of power.
To use Syloki's argument the Cuban missle crisis shows how you can't just have a colonial war. The USSR wanted to make Cuba a "colony", for the US this was unacceptable and they were willing to go to all out war to prevent it, the USSR backed down because in the terms of the cold war they had not got a high enough war score on the US to succeed.
As for the American War of Independence it was the war exhaustion caused by foreign intervention as well as colonial defeats that convinced Britain they could not win ( I'm a true blue Brit but the smartest thing the Yanks ever did was kick George III's butt, so I've no axe to grind). Theoretically she could have continued against the colonists on their own indefinately.
Holland beat Spain because outside help meant Spain couldn't win.
Colonial war should only be possible against claims, war against colonies is war against the owning power, and if they are big enough and determined enough they will not give in. Perhaps the problem is that AI nations can't tell each other to pack it in it is not worth it, were sick of all that shooting noise it's frightning the horses, I guess any game with that level of subtle programming would be something else.
