To be honest here for once,
CKIII is going to be half-baked DLC-platform on release. And it will take years before the game will be relatively playable.
And with each DLC they release (and there will be an ocean of DLC for this game) there's going to be a ton of bugs, and they wont be able to fix all bugs before next DLC(because they care more about making DLC, rather than fix the bugs).
And so the game will never be playable, until they stop mass-producing DLC and hopefully fix the game in the end. But I don't think they will, because it's profitable to work on another game rather then fixing the old one.
Because Paradox is all about money in the end of the day.
I've been playing paradox games since the old Knights of Honor. I've seen them being great devs, and slowly with time becoming the biggest crooks the game industry have ever seen. Making even EA look nice and cute and puffy and pink.
As much as I love history and games like this, supporting Paradox of today is like supporting cancer!
