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$.
So please shit on paradox interactive in this thread.
I only play HoI4 and Stellaris but I imagine this is the same across all their games, their tendancy to lock significant features behind DLC fucking sucks. I have to pay 20$ just to have an intelligence service in a game about WW2??? Lame as fuck.
