Optimized Rebalance

The aim is to restore the historical balance which is lost in the original game, by making few simple rule changes. Many simulations were ran till the current state has been stabilized. Crusader Kings 2 and other mods has given some inspiration.


In the original game, large countries tend to become larger, and swallow the small ones near their borders. Overhaul mods have been developed which restore the balance, at the cost of making the game too complicated, so a long sequence on new rules have to be memorized. Moreover, the overhaul mods are not compatible with the 99% of the other available mods.

The concept of this mod is simple and straightforward: make as few rule changes as possible, in order to end up with a map which looks like the historical one, given that no human players are involved in the game. As the start date is considered the year 1444, and as the end date is considered the year 1821. Dozens simulations have been ran for this mod, using the original map, on the "observer mode" from the day 0 of the game. The final result is that the various small countries in today's Italy, Germany, still survived to 1821, and there are also medium sized countries in Central Africa. Russia, the Ottoman Empire, and the Ming Empire are still holding expanded borders and there are no obstacles in colonization. Finally, observing each game throughout, it became obvious that non European technology groups were lagging in technology, without the European countries invading them; and the reformations in the Catholic Church were spread extensively in Northern Europe. I took care of the Central African countries, to remain intact (as much as possible) by the end of the game.

In conclusion, this is the mod I am going to play from now on, till I see some decent mechanism in the original game which discourages blobbing. This mod doesn't make blobbing impossible, but increases the expansion penalties as the country gains in size.

Always open to structured comments and discussion!
See the Extended Description for a justification of the rule changes.
Needless to say that this mod is NOT Ironman compatible.

Enjoy!
