A number of Steam reviews for EU4 express sentiments like the following:
Fun for a while, then once you realise they announce DLCs and remove content that was already in the game/charge for content that should've been in the game from the get-go or in a free DLC, then you realise how far you've fallen.
My interpretation of this is that DLC has been released that includes "replacements" for features simultaneously removed from the vanilla game (or earlier DLC) but I can't find a list of specific examples of this.
What features have been removed and replaced with equivalent (or considered equivalent) features requiring paid-for DLC?
I appreciate that there's likely some subjectivity in determining that a given feature is a "replacement" for another but given the frequency with which this comes up in recent reviews I'm assuming there are some clear examples of this.
