From Strategyinformer.com: "In many ways, Hearts of Iron III was a bit of a problem child for Paradox Interactive. A grand-strategy WW2 wargame, it was wonderfully ambitious, but a bit bloated and ultimately flawed in execution. Still, for wargamer's and fans of grand-strategy games, it was the perfect marriage of two different but very compelling sub-genres. More importantly though, the pains and gains of Hearts of Iron 3's creation brought about a change of approach in development that led to the stellar success of Crusader Kings II and Europa Universalis IV. Before the former came along, it was actually Paradox's biggest selling title, and its legacy is not to be ignored. The prospect then of a new game that will benefit from the last few years of evolution is actually incredibly exciting.".
