I am sure this has been brought up but coming off a CK3 to EU4 play through how after all these DLCs can we not have a better royal marriage system? The crap shoot of trying to find a nation I can even marry and then hoping they have a queen for me is getting old. Can we have Royal marriages only be for the king and his heirs and the marrying off of the daughters being named as Royal alliance or something? Because early game when you are only allowed to have so many allies it becomes annoying waiting on another nation who just 5 years earlier under your old king had a royal marriage proposal for you but evidently it's never for the heir who's about to take over regardless of his age. I mean of all the obvious "please fix" mechanics I feel this one sticks out most. Royal marriages are not THAT precarious or hard to find back then.
It's very important to note that unlike CK3, EU4 doesn't track individual characters. A Royal Marriage isn't even specifically about the King - the tooltip for the interaction even says you're proposing a marriage
between one of your dependents and one of theirs, even if you get a consort out of it. The RM system here is more about diplomatic relations with the nation in question, and the chance of getting your dynasty on the throne if they don't have an heir. But mind you, even that heir of your dynasty wouldn't be a sure path to personal unions under EU rules like it often is in CK3. You can go for literally generations of marriages without getting a PU in EU4.
It's best to completely disregard everything you know from CK3 when it comes to EU4, much like you should disregard pretty much everything you know about warfare in CK3 when it comes to EU4. It's a completely different system. RM the people you want to ally, ASAP. Heirs/consorts take care of themselves here, and aren't affected much by marriages. Sometimes, you'll even notice a fresh-to-the-throne 15-year-old starts with a 12-year-old heir. It's an extremely high-level system, with enormous abstractions.
