Having chosen your country and start date, the game will start in paused mode. Speed control is very important, so familiarize yourself with the buttons near the date in the lower line of the bar at the top of the screen (I added an orange rectangle around them in the screenshot on the right, click to enlarge). Don’t unpause just yet. I chose France in the Blitzkrieg Campaign, which will make for plenty of action right away and a great, quick, compact introduction.
Before you even touch an army, there are probably a few icons at the top left, just under the main bar at the top of the screen. Mousing over them will give you a tool tip, holding there for a second longer will bring up details. There is a lot to keep track of in Hearts of Iron III, but these icons will let you know the critical details, like when you are at war and with whom, have units to deploy, wasted research or industrial capacity, undersupplied units, and so on.
These are our most pressing concerns, so we will deal with them first.
