Their dlc's have always been overpriced, but there hasn't been one that actually broke the game in years.
Well... Eu4's newest expansion, "Leviathan", has actually broken the game, it is actually unplayable. And the worst part? Even if you don't have the DLC, you're still screwed because the free patch that came with the DLC also breaks the game.
Oh, and also this dlc is 20$.
So please shit on paradox interactive in this thread.
When it's spread out over 5 years it doesn't seem that bad. My steam library is worth like $8000 at full price but I only paid like $2000 for it (over 14 years)
