How does Hearts of Iron IV compare to Hearts of Iron II?
Also, how does it compare to Stellaris, and why did Paradox decide to release two major games within a few weeks of each other?
Because Hearts of Iron IV was delayed multiple times, when it was announced it was supposed to be released in late 2014.
I'm not sure if that's the case. Looking in the game files, it appears that each ideology is divided into sub-ideologies: conservative, liberal, and social democratic for the blue "democratic" ideology; Marxist, Leninist, Stalinist, Anti-Revisionist, and Anarcho-Communist for the red "Communist" ideology; Nazi, Fascist, Falangist, and "Rexist" for the brown "Fascist" ideology; and finally "despotic", "oligarchic", "moderate", and "centrist" for the grey "Non-Aligned" ideology.
They have no excuse then.
Putting as leader of a country as someone whose wiki explicitly says was only an administrator that never held any political position is incredibly incompetent.
