Well, like ludovico said, "just my 2 cents", on the 2 points that really atracted my attention.
- The monarch system: The idea of monarch points is good. The idea of choosing a path is good. The balance in the game is NOT good. The way "the spending points" system is, does not allow you to follow the path you've chosen. That is what provokes the awkwardness of, for example, having a supposily colonisation empire with crap naval tecnology. There are only 2 ways to level your points: monarchs and advisors. Its not enough, if the idea is to choose a path. There should be relevant discounts on the price of related tecnology once youve chosen an idea (or the other way, discounts on the related idea once you choose a tecnology). Just to keep the example, once you upgraded your diplomatic tech tree, you get relevant discount on the exploration idea (or/and another idea that uses diplo points). I could give thousands of examples, but my point is, that's just a matter of balance, that can be fixed in the next months once players give paradox the feedback.
- the monarch: if paradox really wants to give the monarchs the importance they seem to have (the whole point system is highly based on the monarch), there really should be ways to upgrade your monarch.
Thats it.
