Says you. As I recall, there is
always a bunch of guys posting to the effect that it's unplayable because of x,y,z and how could Paradox release it in this state and its the worst Paradox game yet and so forth. Always.

Maybe personally you weren't one of them on the specific games you mention, but they were there. Don't believe me? Go hunt up some old threads from right after those games were released.
They always post stuff like that, too.
...and like that, too.
Well, sorry...but it really is kinda "been there, done that". The folks doing the complaining (almost) always have legitimate issues, and have generally paid their hard-earned money to buy the game. However, as I wrote, I'm sure that if complaining about it would do any good then by now (8 years, in my personal experience on this board), it would be different by now.
You may very well be pleased with 1.3, but I'll bet you there will still be some posting the same old stuff again, because it won't have fixed whatever it was in 1.2 that "broke" the game for them, or introduced a new bug that "broke" the game for them. Often these games don't really hit their stride until an expansion or two is out (and a few patches on those).
I think people just have unrealistic expectactions. In the long run, between Paradox continuing to patch games for years and the efforts of the modders, we always end up with a gem in the end. They haven't let me down yet. My advice is chill & enjoy the ride.
