“Hearts of Iron 4 wields complexity like a swift armor division during the blitzkrieg, allowing it to serve the idea of layered, cerebral, strategic warfare instead of letting it needlessly bog down the experience.”
9/10 – IGN

“It captivates me because—imperfectly, impressionistically, and perhaps a little amorally—it lets me orchestrate the most titanic armed struggles in history, from the fussy economic details to the cut-and-thrust of mechanized warfare. There are other great strategic-level wargames out there. But I have never played anything like Hearts of Iron 4”

“For now, after many dozens of hours, I'm taking a break from Hearts of Iron 4. Not because I'm sick of it; quite the contrary, in fact. What I need to do is some serious reading, some careful planning on what my vision for the United States should be in 1936. And when I've done that planning — when I've formulated my character sheet, as it were — I have the utmost confidence that Hearts of Iron 4 will be ready for me to play a role in world affairs.”
