How hard is Hearts of Iron IV?
What makes it hard: systems — knowing how it works. You get through it by working out what the game is actually doing and coming back with a better build or a better plan, not by faster hands.
Finishing it
Hearts of Iron IV has an ending, but nothing in its achievement list marks it clearly enough to trust — so there's no finish rate to show.
