I was so into mastering all the countries that had developed focus trees, that completely forgot about the existing DLCs and at first, honestly, didn’t really feel the need of them. Well, that was what I was thinking back in the day, when I started playing the game. “Hearts of iron 4” is by far one of the most amazing strategy games out there and when you launch it for the first time, you might think, that its gameplay mechanics and alternative history scenarios cannot get any more detailed and complicated than that.
