Every Paradox grand strategy game tries to capture the essence of an era: the rivalries and discoveries that defined it, the way they reshaped the world. In Hearts of Iron 4, all roads lead to global destruction as players use all the tools of progress to win a spectacular international deathmatch.
The important distinction between Hearts of Iron 4 and the rest of Paradox’s strategy lineup is that Hearts of Iron is a scenario, not a sandbox. It’s a very big, very complicated scenario that can play out many, many different ways, but it’s not the open-ended playground of Crusader Kings or Europa Universalis. Those are games where the Iroquois can conquer the world, or the Viking can become the militant defenders of the Zoroastrian faith.
