The Complete Review of the Eiyuu*Senki Series: Conquering the World, One Heroine at a Time

When curating a premier vault of the best adult strategy games ever made, it is absolutely mandatory to include the Eiyuu*Senki series. Developed by Tenco and featuring the iconic character designs of legendary artist Oyari Ashito, this franchise takes the grand strategy elements of games like Sengoku Rance, mixes them with grid-based tactical RPG combat, and wraps the entire package in a colorful, globe-trotting adventure.

The premise is as outrageous as it is entertaining: You play as a mysterious, amnesiac protagonist who quite literally drops from the sky into the nation of Zipang (a fictionalized feudal Japan). There, you meet the ambitious young ruler, Himiko. Rather than just uniting Japan, you and Himiko decide on a much grander goal: conquering the entire world. The catch? Every single famous historical, mythological, and political figure you encounter—from King Arthur and Vlad the Impaler to Christopher Columbus and Napoleon—is reimagined as a beautiful anime girl.

For fans of world conquest, deep team-building mechanics, and high-quality adult romance, the Eiyuu*Senki series is a monumental achievement. In this comprehensive review, we will explore the defining features of the franchise, break down the differences between the original game and its massive Gold expansion, and look at the spin-offs that kept the community engaged for years.

Core Features of the Eiyuu*Senki Franchise

What elevates Eiyuu*Senki above standard visual novels and makes it a highly respected tactical RPG? The answer lies in its perfectly balanced gameplay loop and phenomenal art direction.

The Gender-Bent Roster of Legends

The primary draw of the game is its massive cast. With over 70 unique heroines in the base game and over 90 in later versions, the sheer variety is staggering. The developers took creative liberties with world history, turning legendary warriors, philosophers, and explorers into distinct, lovable waifus. You will negotiate with a stoic, sword-wielding King Arthur in Britannia, trade blows with a fiery Billy the Kid in America, and match wits with Aristotle. Each character has a distinct personality, unique troops, and a dedicated romance route.

Tactical Grid-Based Combat

Combat takes place on a grid where positioning, unit types, and elemental affinities matter immensely. You must manage your “Brave Points” (a shared energy pool) to unleash devastating special attacks. The rock-paper-scissors mechanic between sword, spear, gun, and magic units requires you to constantly adjust your frontlines and backlines. It is easy to learn but offers immense strategic depth, especially in the late-game and post-game dungeons.

Grand Strategy and Territory Management

Conquering the world isn’t just about winning battles; it is about resource management. During the “City Phase,” you must assign your heroines to govern conquered territories, manage your treasury, fund military expeditions, and declare war on neighboring nations. You have limited actions per turn, meaning you must carefully balance expanding your empire, defending your borders, and spending time courting your favorite generals.

Oyari Ashito’s Signature Art and Erotica

The lead artist, Oyari Ashito, has a very distinct, soft, and beautifully detailed art style that gives the Eiyuu*Senki series its unique identity. The 18+ adult scenes (H-scenes) are highly polished. Because the protagonist is generally kind and charismatic (unlike the brutal anti-heroes found in other dark fantasy eroge), the romantic encounters are vanilla, consensual, and focus heavily on affection and relationship-building.

The Global Campaign: Game-by-Game Breakdown

While the series doesn’t have 10 different sequels like some other franchises, its release history is quite unique. Here is everything you need to know about the mainline games and spin-offs.

Eiyuu*Senki: The World Conquest (2012)

This is the original masterpiece that introduced players to the world of Zipang. After being localized into English by JAST USA, it quickly became a massive hit in the Western adult gaming community.

The original game sets the foundation. You start small, conquering local territories in Zipang before expanding into the Mongol Empire, India, the EU, and beyond. The story is linear but allows for tactical freedom in the order you invade certain countries. It perfectly balances visual novel storytelling with addictive “just one more turn” gameplay. With multiple endings depending on which faction you heavily ally with, it offers over 60 hours of gameplay.

Eiyuu*Senki Gold (2014)

A common misconception is that EiyuuSenki Gold* is a sequel. It is actually a standalone reimagining or an alternate timeline of the first game, and it is widely considered the definitive way to play the series.

In Gold, the protagonist lands in Zipang, but the geopolitical landscape is entirely different. The story is fresh, the dialogue is completely rewritten, and the combat system receives a massive overhaul. Gold introduces an item-equipping system, rebalances unit stats, adds new combat skills, and introduces highly requested new historical figures (like Ivan the Terrible and Date Masamune). The UI is sleeker, and the adult content is expanded. If you have to choose only one game to play in the franchise, Gold is the undisputed champion. JAST USA also provided a stellar, uncensored English localization for this version.

Eiyuu*Senki WW (Web/Mobile Gacha Spin-off)

Launched around 2019 and hosted on platforms like DMM and Johren, Eiyuu*Senki WW (World War) was a free-to-play gacha game adaptation of the franchise.

It brought the familiar grid-based combat and Oyari Ashito’s artwork to mobile browsers. It expanded the roster to over 300 variations of characters and featured live-service events. While the 18+ scenes were still present for the rarest characters, the game suffered from typical gacha grinding mechanics. Unfortunately, EiyuuSenki WW* officially shut down its servers in 2022. While it is no longer playable, its massive repository of new artwork and CGs is still highly sought after by hardcore fans of the series.

Overall Review & Summary

Eiyuu*Senki stands as a titan in the adult tactical RPG genre. It proves that a game can deliver top-tier, explicit fan service without compromising on deep, engaging gameplay.

Feature	The Good	The Bad
Story & Lore	A hilarious, creative, and engaging take on world history with an incredibly lovable cast of characters.	The overarching plot is somewhat lighthearted and predictable; don’t expect deep philosophical twists.
Gameplay	Highly addictive mix of grand strategy map painting and grid-based tactical combat.	Managing a massive roster of 70+ characters in the late game can become tedious and grind-heavy.
Visuals & Art	Oyari Ashito’s character designs are iconic. The UI (especially in Gold) is clean and intuitive.	Some enemy unit sprites lack variety and get recycled frequently throughout the campaign.
Adult Content	Beautifully drawn, affectionate, and varied H-scenes that feel like genuine rewards for your conquests.	Players looking for darker themes or extreme fetishes will find the vanilla romance too tame.

General Community Feedback

If you browse the Steam reviews or the Visual Novel Database (VNDB), the EiyuuSenki series is universally praised. EiyuuSenki Gold, in particular, boasts overwhelmingly positive scores.

Players consistently highlight the sheer volume of content. Many reviews point out that even without the 18+ scenes, the tactical combat and nation management are strong enough to rival mainstream, SFW strategy games. The community also frequently praises JAST USA for their excellent, high-quality localization, which captures the distinct voices and historical puns of the massive cast perfectly.

The main criticism from the community usually revolves around the endgame pacing. When you control 80% of the globe, mopping up the final few territories and grinding levels to beat the secret post-game bosses (like the Knights of the Round Table or the ancient gods) can feel like a massive time sink.

Conclusion

The Eiyuu*Senki series is an absolute triumph of the adult strategy genre. Tenco managed to bottle lightning by combining the addictive nature of world conquest with the undeniable appeal of collecting beautifully drawn anime heroines.

Whether you are stepping into the boots of the amnesiac tactician for the first time in the original Eiyuu*Senki, or experiencing the refined, ultimate strategic warfare of Eiyuu*Senki Gold, you are guaranteed dozens of hours of premium entertainment. Assemble your army of historical legends, manage your empire, and conquer the world—this is one campaign you do not want to miss.
