The guys at Paradox France
(formerly AGEOD) have been making strategy games for a long time. Admittedly, I haven’t been a fan of all of their titles mostly because of the micromanagement of minutia which always annoyed me and, I thought, slowed the game.
This time, Napoleon’s Campaigns II has a very focused gameplay and only two resources to manage; conscripts and money. I suppose you could say that diplomacy is another resource to manage as well, but it all boils down to those two things.

The point of the whole game is quite simple, in those ten years of fighting you need to become the dominant power on either land or sea, have Napoleon recognized as Emperor of France and have two of your family members on the thrones of other countries. You can do that by conquering other countries and then carve it all up and put your own family members on their thrones.
You can play as several countries and each has pros and cons as well as specific types of units. So for example, if you’re playing as Russia you’ll have nearly endless bodies to throw into a war, but almost no money. For Britain it’s quite the opposite. Since nothing ever happens in a vacuum, there are historic events and such that will also affect the game at certain times. These further create uniqueness for each country.
