It can take a while to learn but by all means this game was worth the learning time. Theirs nothing more satisfying then making a plan and executing it perfectly or maxing your commanders skills. But I do have to say the game crashes more then your average game. I dont recomend this game if your not a patient person. I would definitly recomend it if you like a challenge

Certainly one of the best strategy - war history games I have ever played in my life (Just look at the bloody hour counter!! and those are online). Very deep mechanics and too many stuff to learn, not easy but certainly not impossible. Taking away the mods, is limited when it comes to play in a sandbox way; although you have certain degree of freedom, some things just won't happen, that is in historic terms. As for technology and military focus you really are the ruler of your country: whether as Germany you start focusing on building a decent Kriegsmarine or as Japan on building tanks to send them to support you Italian ally in Africa.

I think the game can suit your gamestyle depending on how much micromanagement you want to do or simply if you just want to FF the game only watching how your armies advance. Personally, I try to balance between both: invading the Soviets with Germany I prefer to go fight by fight meanwhile for crushing China with the Japs I just let it go faster or also checking from time to time how is the US fleet managing to stop the Japanese advance.

Certainly a game that needs tons of time and pacience (that also still depends on your gameplay). The only major setback is the bloody problem that crashes it almost every 20 minutes almost every time, and although it is said that there is a fix on the dev's page, is not precisely the word straightfoward on how to fix it.


Overall 8/10 because of that damn issue.

P.S. I hope it dissapears completey with Hoi4

One of the few games where you build up an extremely elaborate plan to take over the world only to watch it ruined by an unsuspecting army of apparently superior French tank engineering.

Well this game....
It altered so much stuff from HOI2 engine that makes me play both this and Darkest hours still a lot.
It is hard to decide which is better.

Paradox made HOI3 not just different also on the gameplay part, but the new autonomous historical ai can make the game a little more ahistorical than the earlier games. Not saying it's bad, just different and some people may not like it.
The Combat system got a lot complicated, Technologies too. But theres a catch...
If you don't like any of these new features or are just starting out you can put individual parts of country into AI hands, which helps a ton if you are just learning the game.

I consider the HOI series one of the hardests off the Parados titles so this game made it a lil bit easier to start I think, especially with the AI features. But I really suggest you play Darkest Hour too after seeing this game. It is a really well made HOI2 enhanced edition.

Overall Score: 7/10
