Eiyuu*Senki: The World Conquest

Eiyuu*Senki: The World Conquest is a sprawling tactical RPG and visual novel hybrid developed by Tenco and originally brought to the West by Fruitbat Factory. This title is widely credited with perfecting the “world conquest” subgenre for the anime community, blending grand strategy with a lighthearted, harem-style narrative. Unlike more serious strategy titles that focus on gritty realism, this game offers a colorful and often absurd reimagining of global history, where every legendary conqueror—from Napoleon to King Arthur—is a beautiful anime heroine. It’s a massive adventure that feels like a “greatest hits” of history and mythology, designed for players who enjoy deep unit management and a vast roster of characters to recruit.

As the latest entry in the series, Eiyu*Senki Gold – A New Conquest represents the most complete and refined version of the experience. It builds upon everything that came before, adding new content, improved mechanics, and a more polished overall design. For players looking for the definitive way to enjoy the series, this is the version to start with.

The Story of Eiyuu*Senki: The World Conquest

The story begins when the protagonist, a young man from the modern world known as the “Servant of Heaven,” is suddenly transported to an alternate version of Earth. He quickly discovers that this world is trapped in a state of eternal warfare, with nations constantly battling for territory and resources. In this version of reality, historical figures appear as powerful female heroes, each leading their respective countries with distinct personalities and ambitions. The protagonist’s arrival is seen as a divine omen, and he is soon goaded into helping Himiko, the cheerful and ambitious ruler of the nation of Zipang (a fantasy version of Japan), in her quest to unify the world and bring about a lasting peace.

What follows is a global odyssey that takes the player from the shores of the Far East to the heart of Europe, the Americas, and beyond. The narrative isn’t just about military might; it’s about the clash of cultures and personalities. You’ll witness hilarious and heartwarming interactions, such as Oda Nobunaga’s fiery temper clashing with the innocent charm of Sun Tzu. While the overarching plot involves stopping a mysterious evil force known as the Illuminati, the true heart of the story lies in the “what-if” scenarios: seeing historical rivals become allies and building a massive, diverse family of heroes. It’s a tale that balances comedic harem antics with moments of genuine camaraderie as you work to turn a world of conflict into a unified alliance.

Eiyuu*Senki: The World Conquest Gameplay

The gameplay of Eiyuu*Senki is a masterclass in macro-strategy and grid-based tactics. The world is divided into a massive map with over 100 cities to conquer. During your turn, you are given a limited number of Action Points, which you must decide to spend on attacking new territories, defending your borders, or completing side quests to strengthen your bonds with your heroes.

The game introduces a Risk-style defense mechanic, where heroes used for an attack or an event are unavailable until your next turn. This forces you to carefully manage your roster, ensuring you don’t leave your newly conquered lands vulnerable to a counter-attack from neighboring nations.

Combat itself takes place on a 3×6 or 4×4 grid (depending on the version) and utilizes a turn-based system where positioning is everything. Each hero belongs to a specific unit type—such as Sword, Spear, Gun, or Magic—and follows a rock-paper-scissors affinity system. For example, Gun users can attack from the back row but are weak to melee charges, while Magic users can hit the entire board but are often fragile.

Success in battle isn’t about leveling up through grinding; the game eschews traditional EXP for a system where you upgrade a character’s “arms” (a combination of health and power) using war funds or by completing their unique side stories. This ensures that every hero in your army feels distinct and valuable throughout the 50+ hour campaign.

Review and Community Feedback

Since its international debut, Eiyuu*Senki: The World Conquest has earned a “Very Positive” reputation, particularly among fans of tactical RPGs like Fire Emblem or Sengoku Rance. The community frequently praises the breathtaking artwork by Oyari Ashito, noting that the character designs are so high-quality that the game often feels like an interactive art book. Players also appreciate the “just one more turn” addictive nature of the world conquest system, where the constant stream of new characters and territories to unlock keeps the momentum high. The localization by Fruitbat Factory is also a major highlight, often cited as being witty and perfectly capturing the eccentric personalities of the massive cast.

However, some critics in the community note that the story can feel a bit thin for those expecting a deep, Shakespearean drama. Because the game focuses so heavily on character interactions and silly “slice-of-life” events, the main plot sometimes takes a backseat to the harem antics. Additionally, while the tactical combat is solid, some players find the difficulty spikes in the later stages of the game to be quite steep if they haven’t been diligent about upgrading their secondary units. Despite these points, the consensus remains that it is a foundational title for the genre, offering an immense amount of content and a level of charm that makes it a must-play for any fan of anime strategy.
