In the name of world peace, we shall conquer on Steam!

If you’re an all-ages visual novel fan who is invested in the Steam ecosystem, then get ready for one of my most anticipated titles: Eiyu*Senki – The World Conquest.

Originally released in the West back in 2015 on the PS3 under the title Eiyuu Senki – The World Conquest, this awesome title won the hearts of many here at Operation Rainfall. But if this was released in the West two years ago, why is only now coming to Steam? Well, there is a good reason for that.

While localizing the 18+ content is one of the main reasons for releasing this title on PC, Eiyu*Senki also had its translation touched up.

JAST USA has worked to not only retranslate the game but also localized the eroge scenes that were in the original PC release. That said, obviously, the Steam version doesn’t have those scenes. However, JAST USA still wanted to release an all-ages version of the game for those who aren’t as fond of 18+ content. And that’s perfectly understandable, eroge isn’t for everyone after all.

As for the game itself, it’s a story of world conquest. Starting from the tiny nation of Zipang, you’ll set out to conquer everything in the name of world peace! Trust me, it makes sense in context.

Probably one of my favorite images in the game. You just have to love how badass Alexander the Great looks

One of the key selling points is that all of the characters are based on historical figures. So for example in Zipang (basically Japan) you can recruit Oda Nobunaga, while in America you’ll meet up with Christopher Columbus and Billy the Kid. Heading to the EU? Get ready to throw down with Ceasar, Napoleon, and Hannibal. It makes for quite an entertaining adventure.

Eiyu*Senki – The World Conquest is available right now on Steam. While normally $29.99 until November 17th it’s 20% off which means you can begin your quest for peace for only $23.99.

Even if the 18+ material isn’t your thing, there’s plenty of fanservice and gorgeous character designs. Case in point, meet Gaius Julius Caesar. Yes, she is as beautiful as she is rich.

If you’d like some more in-depth information please consider checking out this article I did about the 18+ release. No worries, there’s no NSFW images there, just be careful about the links.

Finally, for fans of the 18+ version who want a Steam restoration patch, JAST USA is in talks with the developer according to the comments on this page. (NSFW Warning due to Goemon in the bath). I’ve also included a screenshot below:

Hey, at least they’re being open about this. Let’s hope that Tenco and JAST USA can get a patch made in the near future.

We’ll have to wait and see, but hopefully, Tenco is able to help make this happen. In the meantime, remember that you can purchase the 18+ version of Eiyu*Senki – The World Conquest digitally on JAST USA’s website or in physical form on JLIST. Please see the 18+ article for those links.

Be sure to check out the press release, trailer, and gallery below as well!

Happy conquering everyone!

Eiyu*Senki Releases on Steam Today

Eiyu*Senki is a hybrid game that merges the storytelling depth of visual novels with the gameplay of a tactical sim. Your goal is to conquer the world in the name of peace, and along the way you’ll be able to recruit over 70 historical figures as allies, such as Marco Polo, King Arthur, Rasputin, Aristotle, all genderbent as cute girls.

Eiyu*Senki was previously released on the PS3 under the name Eiyuu Senki but suffered from translation issues and cut content, deemed too mature for the platform. This new release of Eiyu*Senki is spiritually the “Director’s Cut” of the game, providing an experience closer to the original Japanese release with an improved translation, some restored mature content and reduced price. A completely uncut and uncensored version is also available directly from the JAST USA store.


Set in a world run by powerful nations where heroes battle one another for control, Britannia wishes to unite the world through peace, while the European Union has taken an aggressive stance. The seafaring nation of Vinland thrives on pillaging and plundering, while far to the East, the island country of Zipang is faced with civil war. In the midst of all this Himiko, a ruler in Zipang, seeks to unite the world for the sake of peace. Her ambitions are high but so far she has only seen defeat. One day, while retreating from battle, a mysterious hero falls from the sky and joins Himiko’s cause. The two now set their sights on the war burning around them.


Eiyu*Senki takes you on an adventure to the ends of the earth and back as you help Himiko save the world from an endless war. You’ll meet unique characters inspired from real historical figures and mythological icons, like King Arthur and the Knights of the Round Table, Marco Polo, Christopher Columbus, Rasputin, Kamehameha of Hawaii, Beethoven and many more. There are over 70 characters who can join your side, each with their own valuable battle skills and side-quest storylines. Your battle party can have up to six members, so you have literally millions of possibilities to form your “dream team” to take down monsters, zombies, dragons, and evil villains. The tactics based combat starts out simple and grows in difficulty as new enemies and abilities are unlocked, making the gameplay easy to learn yet increasingly challenging and addictive.

The leveling system is unique among RPGs, with two ways to level-up your characters’ combat effectiveness: their troops, and their relationship with you. Purchase additional troops for your teammates every turn, increasing their damage output and stamina, or complete side quests and romance storylines to unlock new combat skills and abilities.  If you are a completionist then it will take 40 to 50 hours to experience all the characters side stories. It’s a massive game that is super fun to play!
