Waste of 10$. Is it cause it's a bad game? Definitely not. It's an insanely great game.. But it doesn't work. It used to crash every 30 minutes to an hour, and not it won't even start, just crashes. It's too unreliable to buy, only if you have money to throw out. Definite shame.

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 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.

8 hours into this game and I have accomplished the following:

Nothing.

THis game is very complex and extremely slow paced. However, a game that requires you to put hours upon hours into it to accomplish very little is a game that is worth the money. With so many garbage, instant result, games out there today, this game is a beacon of tenacity (becasue that is what is required to go more than 5 minutes).

Highly reccomended, especially if you love the Paradox type games and have a love for all things World War II related.
