The latest DLC, Leviathan, and the "free patch" accompanying it totally broke the game (just one example: when you try to colonise the "New World" you discover that the natives are already so advanced that they kick you back all the way to Europe). Also, the bug list is mindblowing.
To Paradox's credit, they took a breath and decided to slow the production of new content until a great number of the outstanding (in the literal sense of the word ) bugs are fixed, while also working on the balance of the game and the AI. The latest Developer's Diary promises the moon about this issues. We will see.
It must be said, however, that the game is now too bloated and collapsing under its own weight. I have 600+ hours on Steam and all the DLCs (I'm a compulsive completist) and there are things I still haven't a clue what they are about. In comparison, Crusader Kings II is, possibly, as richer in content, but it doesn't forces you to learn everything. You don't need to know how Satanism works unless you decide to secretly embrace it. The social and religious practices in the Scandinavian region are replicated in a very interesting way, but you need to bother about them only if you are from that region. And so on.
Actually, half of the fun of learning CKII comes from the fact that you can imagine to be someone tasked to rule a fief - and you don't have a clue about how to do it. Chaos and very funny situations ensue. EU4 asks you to have a degree in political sciences up start or you will literally not understand what happens when you do something, and why. The Wiki helps but, by now, too much of the game looks like work.
