The first campaign is Germany 1939, where you get Germany ready for WWII. HoI3:TFH set you up with four campaigns to choose from with different objectives and controls. There’s so much data being created, that in many cases you can customize the data to read the information you find more valuable, whether it be information on border allies, Axis powers, or whatever you deem important to the mission. Each topic has its own tab at the top of the menu and inside, each aspect is crammed with information.
The game is broken up into Diplomacy, Production, Technology, Politics, Intelligence and Theatres. Sure, it may look like a lot of spreadsheets, but deep down, you control every aspect down to the nuts and bolts. Hearts of Iron has prided themselves with in depth strategy games. The first Hearts of Iron dates all the way back to 2002.
Hearts of Iron III: Their Finest Hour is the latest expansion to Hearts of Iron III developed by Paradox Interactive.
