As one of the "old" fans of paradox games (HOI 3, jesus people who played HOI 1 must be dinosaurs) I can say with absolute certainty it is going to be crap. it's not a probably, it's not a almost certainly; it is going to be. This is because that's just how paradox is now, they're lazy money grabbers like any big publisher/developer now, once you cross that line you're dead, no coming back. Ok so HOI 3 was good, Vicky 2 in 2012 was good, EU4 I don't think is very good cause in order for it to be good it has to be $200 in DLC, same for CK 2. HOI 4 had some nice quality of life changes but was ultimately shallower, Stellaris took some time but got good too and with comparatively fewer strings attached but that's cause it's made by a different team. And then we got Imperator. Oh boy. Imperator was shallow as shallow could be, a puddle on the sidewalk has more depth than that game does, and right away everyone could tell why: so they could add the "depth" later with DLC. Now nobody bothers to ask the question WHY is it so shallow? They had 4 years of development time, they have all that DLC money from EU4 and CK 2, so just what the fuck was going on? Simple answer: The CEO and big wigs took all the money and development was token. Hey remember when they said "Hoi4 before 2016 and Vicky 3 before 2020"? CAUSE THEY GOT 2 MONTHS TO ANNOUNCE AND RELEASE VICKY 3 THE FUCKS! And why is there no Vicky 3 despite Vicky 2 coming out in 2010 but there is a CK 3 even though CK 2 came out in 2012? DLC of course. And there's people who defend such scummy tactics by saying "oh but it's not microtransactions" as if I should be thankful that I'm getting only fucked in the mouth and not the ass, or -my favourite one- that it helps with the longevity of the game. I DON'T WANT A FUCKING LIVE SERVICE! I want a good finished game on release with 1 or 2 DLCs that just add some goodies on top like with Vicky 2 and HOI3, the "longevity" they speak of is the stuff in EU4 and CK 2 where they retroactively removed content and paywalled it behind DLC that added other stuff.
So ya, CK 3 is gonna be shallow af, broken on launch so they can just patch it later by making you pay for it, and then they're gonna say "oh but it has 5 times as many events as HOI4 don't you know?" despite said events are actually just the same 2 events over and over again with different character names copy and pasted in, JUST LIKE IN IMPERATOR! Also look at Imperator visually, it just looks like a crack of CK 2 or EU4, which it is, so you can bet your ass CK 3 will just look like CK 2 but somehow worse cause they're still using the Clausewitz engine which was made in 2007.
Oh and it will be made for and catered towards 3 year olds so it can be as accessible as possible.
