If you are a fan of Paradox Games, Imperial Glory, other Geo Political games such as Super Power 2 you will enjoy this game. The game can be a little overwhelming at first, There is a bit of a learning curve but can easily be learned even with out the tutorial if you have played similar games.
I love the amount of depth this game has, Although war is a major focus point it is far from being the only point. One thing i dislike in similar games is a vast amount of waiting around with nothing to do. This game has plenty to manage while you are waiting for troops to build. If i had to compare this game to another game Supreme Ruler comes to mind as far as what you can do micromanaging wise. As much as i love the Supreme Ruler series this is in my opinion a superior game for the sole reason that i find this game more of a joy to play.
If you are looking for a strictly historical game you may be a little off put as the game is guided towards world war 1 events however it is only a suggestion, I have yet to play a game that was the same, There were times that world war one happened without a hitch and i was fighting off Germans in Belgium, Other times I became the cause of a World War due to my military expansion of Romania. There were times that other conflicts would prevent world war one but start other conflicts around the globe such as Colonial territories rebelling against their owners. The randomness of this game can be a blast.
The game also comes with an Editor that anyone can use, This means that if you want to build a world war two scenario you can, Do you want to recreate the Roman Empire you can, Whatever your imagination can come up with. These scenarios can also be uploaded on the Making History website for all to download.
The Developers are extremely active and listen to the community, I have never experienced the amount of help that is given by the developers to the players than in this game. They have made it clear that this game will continue to be a major focus with continued updates and added features for the foreseeable future.
If you are looking for a game in which you will keep telling yourself one more turn and you realize that was the 30th time you said that then here is the game. Would highly recommend.
