Opaque UI and hidden rules + hidden rules changes do indeed plague the game still, and the effects can certainly be seen in this thread, but the concept of perpetual intermediacy comes to mind also. We have a mix of both in this case.
Though it's worth noting that for whatever reason, the vast majority of players wind up being perpetually intermediate, so making the game's rules accessible and understandable to them is kind of important.
Opaque UI? I just tried calling Hansa into a war (which according to my declare war screen they would accept), but since they were already in a war against Burgundy with one of my target's allies (or the target itself, I dunno), they were not able to join. After their war with Burgundy ended, I was unable to get them to join my war because they had already been called to all active wars.
Sigh.
Box should just not be crossed if they're unable to join the war for whatever reasons.
The new expansion looks kind of poopy to me if the proposed map was part of it. In any case, I feel your pain OP, I take breaks from the game a lot, and when I come back, new rules, nothing previously posted matters or works anymore. Okay, the game evolves, EU3 did as well, it's a matter of life with this franchise, that I do kind of still love, even though EU4 didn't take the same place in my heart that EU3 holds.
However, as Spain you can beat France silly, you did something wrong. You must have taken a mil idea, there is no real other response to that. I beat them up all the time. Maybe your were playing on hard, but even then... I mean, England can do it, and Spain actually has more money than them and a shorter trip to deliver mercs, and Aragon probably won't give access, well, to either of you.
You are in a very defensible position in Spain, if you keep a close eye out (and you should have destroyed every other fleet in the Western hemisphere in the first 50 years) then they can't bring troops into your land because there is a string of mountains protecting you. Just turtle until they peace out and then break out. There is a mandatory white peace with no action after 5 years.
Also, you really should have beat the poop out of Austria to start and gotten the Inheritance for yourself, just saying, see my threads.
This was right at the start of the game, before I'd gotten any new tech at all. I had Burgundy in an alliance and we were winning the war, then inheritance happened and 30,000 of allied troops vanished into the ether. I saw your thread and am planning on trying it out. Always been wanting to try inheritance + Iberian wedding, but last time, Savoy (I think it was Savoy) inherited Burgundy even though Austria had released Styria. Silly royal marriages.
