You can dress up how you describe new "features" however you want and it won't change the fact that most of these "features" are naff buttons you press or just pointless, for example you're calling "Draft Transports" a feature when all it does is build some boats?? Seriously? All monuments are are a set of modifiers you can pump gold into. Music and Sprites don't count because they're useless bloat you unnecessarily ship with actual gameplay affecting DLC to justify a higher price (Unit sprite packs not selling enough eh?). Carpet siege as with all QoL should be free, etc etc.
Primarily what I don't understand is how official eu4 content is so lackluster. Modders are making content that blows DLCs out of the water constantly and they're often individuals or small teams who don't take a paycheck from the game and just do it out of passion, rather than being an actual multi-national games studio like Paradox.
At the end of the day I think 8 years is too long to support any game for, especially eu4, as the development team changes and more and more dlc comes out it becomes increasingly more expensive and less time effective to create new content for that game, as you have to mess around with testing unusual dlc combinations (the number of different dlc combinations has got to be in the thousands at this point right?) and 9 year old spaghetti code that almost undoubtedly wasn't written by whoever is working on it now. Not to mention how the vision of the game changes as the project lead inevitably changes. Another thing to consider is that consumer attitudes change and what was once deemed cool no longer does it for fans, with an 8 year game support life cycle as you're finding now you have to try and desperately hamfist the game into doing what it wasn't designed to do (playing tall is the example I'm thinking of.)
I know that eu5 is being worked on currently and I can say without a doubt that even if it's the greatest game ever on launch (it'll probably be a critical flop since it'll be a shallow and unchallenging husk of a game with obviously missing features and QoL being withheld to sell more dlc down the line) then by the end of its life cycle it'll be considered the same as eu4 is now if managed the same.
Oh btw the very fact you had to make this thread should tell you everything you need to know.
Yes I'm fully expecting a ban because lol can't criticise pdx.
(btw I'll take back everything I said i you rework the economy.)
