I have said it before, and I say it again: the target of our game is not that the human players shall share Europe among them - if 8 or 9 human players ally no one will be able to stop them - they can expand freely, and it is as unhistorcal as it can be! To ensure a healthy game the maximum-two-humans-in-one-alliance rule is needed.
It will not be changed: and due to the compromise this is out of discussion. Sorry, but I have been adviced, in order to make a interesting game, to avoid 100% human dominance. I don`t understand how an alliance consisiting of Scandinavia, Austria, England, the Mamelukks, France, Saxony, Lithuania, Venice, Portugal and the Ottoman Empire can bring any new aspects to the game - it will make it boring! And if two or more alliances commit themselves to assist each other - which may happen - I doubt that they always will be true to eachother. The badboy points for declaring war - and the fact that they doesn`t need to lose stability for dishonour the "call" - make them less tighter, and less dangerous. AND - Gottwaldus: We have the possibility to forbid two alliances to cooperate that near, too - since you mean it could be a problem... (which I don`t)
