I think this is part of the adjustment from the typical 4X symmetric start to the Crusader King's approach of having very unbalanced starts between rulers.
Yep, this is what seems to me coming from some of the negative comments I've seen. Yes, it feels like a 4X game at the start through mid game but once the star nations are established it is more like EU4 where it isn't "fair and equal" and some nations (France) are big and badass and not to be trifled with. This if anything is a positive progression of the semi-genre where in most 4X games there is more of a focus on expansion and once you do that you pick off people one by one gaining steam. In this you have to actually do diplomacy and shit and like EU4, you can find your self fucked if the wrong nation takes an interest in you.
I think the mods are going to be awesome after seeing what paradox themselves put in. Just having a mod that adds a ton of NPC "monster" races would be great.
