If you don't have a very strong rig to support HoI4 and play it properly, you should definitely try HoI3. Since my review comes this late, I'll try to give a few pointers why this would still be relevant to play now that HoI4 is out (single player mode) and also give my impressions, as I remembered from when I played the game.

Why is it still relevant?
The order of battle in HoI3 is the most immersive part of the experience. The new version doesn't have anything similar and being able to assign commanders all the way down to the level of army corp makes you feel like the actual strategist in charge of the army. The generals available are alter-egos of generals that commanded armies during the actual WW2 and they even have actual portraits, not an artistic icon. In the new game, you ony add the chief of any single army group, no matter how large it is. You're allowed to disperse the divisions to whatever theatre with no repercussions and in general organising your troops on the frontline is broken in the new game (at least as it is in v1.1.0). You don't get a lare pool of generals to use, as you did in HoI3.

The battle system is just as easily exploitable in HoI4 as it is in HoI3, so why not play the more immersive version? Unfortunately, the new one brings a superior production system, which is also a good spin imo.

Air planning is strictly better and also more immersive in HoI3. You can specify a cone, a sphere or region(s) that a squadron should cover and it can be customised to as far as the range of the aircrafts permits. Unlike in HoI4, you can make sure that your aircraft engage the enemy only in the areas that are relevant to your plans. It's not very intuitive, but once you get the hang of it, you won't want anything less.

Ultimately, the best part about HoI3 was the learning curve[\b] for me. It is good that HoI4 made things more intuitive, especially for returning Paradoxians, but the learning process was part of the experience for me and that's cool. If you're a new player to the HoI series and think you'll want some explanations and tutorials, you simply have more for HoI3 and they're better, so again this will be your #1 option, imo.


Actual things about the game
Lots of stuff are broken. Performance wise, it works well for me (even on a laptop), but there are plenty bugs still. Planning your divisions and triggering various manoeuvres are so immersive that it makes all issues fade away. The Ai is not very good, but this won't be obvious in your first playthroughs. You have multiple areas that you'll have to pay attention to in order to do well. One single game can take tens-hundreds of hours, but if you focus you can move through at a faster pace, if you must. But I didn't, the micromanagement is too tempting in HoI3.

After a couple tries at the game and after finally understanding it i decided to play as Germany for the 2nd time (First time i didn't understand the game so Poland,France and the UK invaded me.) So here is me trying to make Germany Great Again.

-Early 1936: Forced all of my time into making Germany lose neutrality
-late 1936: Invade the Swiss to bypass the French Border
-Early 1937: Invade Hungary since they were a smaller country
-Mid 1937 Swiss rebels start appearing out of no where even though there is a ton of MPs in Switzerland
-late 1937: Stop rebels and decide to Conquer Romania
-Early 1938 Annex Austria and decide to accept Bulgaria into Allies. By now Nationalist Spain,Portugal, Italy, Japan (and all of it's Puppet countries are in the Axis.
Mid 1938- Decide ♥♥♥♥ it and Declare war on Lithuania to get Memel back but afterwards realise that there is an event for that
(Spend all of the rest of 1938 to march 1939 making troops.)
March 1939- Tell poland to give me Danzig. Poland refuses
rest of 1939- conquering all of the Allies in Europe. Eventually took the UK after a couple tries
Early 1940- Declare war on the Scandanavian countries above Germany (Non were a part of the Allies for some reason but mainly drifting torwards it.)
Mid 1940- Conquer Norway, Denmark and Sweden all in this time period (kek)
Late 1940- build up troops in these countries and realise that i could build stuff on greenland and ice land
Early 1941- Don't want to deal with Iceland so i made it a Puppet of Germany
Late 1941- Help out Italians in North Africa and make several puppet states out of North Africa
Early 1942- Revoke Non-Aggression pact with the USSR
Mid 1942- Take Movska and Stalingrad (Historically accurate so far)
Late 1942- Nearly made Soviets surrender but then start pushing my mighty panzers back
Early 1943- Finally defeat Russia
Rest of 1943- Rebelions happen all over the USSR and put troops everywhere in Russia(Even in Siberia)
Early 1943- Make Communist China my puppet state
Feeling good by now since i have destroyed all of Bolshevikism in the World
Mid 1943 - Take over Australia
By now my armies are very stretched thin
Establish bases in Australia to send over to the US
Late 1943 - Launch invasions in the US and canada
Early 1944 - Alaska is mine (Fallout 3 flashbacks)
Late 1944 - Canada is mine now
Early 1945 - All of the US is mine
Haven't paid attention to Europe and Asia for a while by now
Mid 1945 - Right when i was about to invade Mexico, Rebels in Europe are popping up in my regions so i frantically send all of my troops back to Europe and Asia to put them down after i do that however, rebels pop up in Canada and US and take back their nations
Late 1945 By now i start getting Frustrated and about to give up; Right when i finished putting down rebels in Switzerland, France and the UK, Rebels appear in the USSR and take back a quarter of the country near Asia.
I eventually Rage Quit from this and deleted the save
i wish i had a screenshot of the nation at it's height...

10/10 Wouldn't make puppets again and was very historically accurate
