Easily the best strategy game available right now. Lacked a bit of depth at release, but the two DLCs have been great. Hundreds of hours of potential, and even more in multiplayer. Absolutely recommended if you like strategy games. Graphics are great too, though the 32-bit single core engine is a bit of a letdown.

If you like WW2, and you have enough time on your hands, this game is near perfect. This game fulfils everyone of your micro and macro desires, with gorgeous graphics and refined combat system. Only reason its not 10/10 is because it chugs in the late-game.

Best. Game. Ever. No Argument. Ok, fine, the AI is a bit bad, but the level of detail is amazing, and the Modding community is the best. Just ever, it can fix whatever problems you may have, also the production system is the best, and also the air combat is the best.

The game was quite good but not as good as Crusader Kings 2. The game is about World War 2, which there are a hell lot of games about, making Hearts of Iron 4 very cliche, the game has a huge learning curve, which can make a lot of players quit. But other than that, Hearts Of Iron 4 is a brillian game.

it's a great grand strategy mixed with sandbox, alternate history (if you want to), accurate history (again optional) and actual balanced game play the only downside of it is the lag and stuttering that happens when there's a lot happening in the game and the game is calculating.
