You sit upon the Dragon Throne. Memorials pile high upon your desk; urgent dispatches from the frontier and the undercurrents of the court close in at once. A single decision may buy a decade of peace—or ignite the flames of a dynasty's fall. Choice of History is a deeply strategic historical simulation built around the core of imperial decision-making. From across millennia and five civilizations—China, Rome, Britain, America, and Russia—you shall choose one of **555 real sovereigns** to ascend the throne, holding the rise and fall of a nation in your hands. At every turning point of history, you make the choice that is yours alone—history will not make the move for you. It only sets the throne in place, then watches in silence as you play. Core Gameplay: Place Your Stone at Every Crossroads The game is built on a turn-based simulation advancing by year and month. You will again and again face documented historical events: a sudden flood, a frontier rebellion, a remonstrance from a scholar-official, a succession dispute within the inner palace. Each event offers multiple branches of choice, and your decision rewrites faction relations, the treasury's balance, and the hearts of the realm—in real time. There is no "right answer" here, only cost and trade-off. Cutting taxes wins the people's favor for a season, yet empties the coffers; elevating a worthy hermit may rally public opinion, yet provoke the hereditary clan. Every move you make reshapes the course of the dynasty. World & Narrative: Written Within the Very Fabric of History We have built exhaustive data and event libraries for **326 Chinese sovereigns** and **229 rulers and chieftains of the world** (civilizations such as Rome, Britain, America, and Russia), and authored fully fleshed-out scenario scripts for core monarchs—such as the complete narrative arc of the eighteen "Class-A" emperors. From the chronicle sketches of the Three Dynasties, through the fiscal maneuvering of a dynasty's zenith, to the storms of its twilight, the game rests upon rigorous historical scrutiny, so that every reign stands on solid ground. Narrative is not a linear lecture. Events are driven by a three-engine core of "branches + faction relations + flags": your choices leave behind narrative flags, and **causal gating** decides whether later scenes may be triggered—foreshadowing planted years before echoes, converges, or recoils upon you in time. We have recently added a narrative memory layer (letting events across reigns echo one another) and a **vernacular mode** (lowering the barrier to reading), so that what you write becomes a self-consistent national history, unique to you as its sovereign. Systemic Depth: Three Pillars Upholding the Strategic Dimension ① The Tech Tree—1158 Nodes of Civilizational Evolution Ten great branches (agriculture, military industry, construction, commerce, culture, medicine, astronomy and mathematics, law and rites, natural philosophy, and even a "cultivation" fantasy line) form 1158 tech nodes. Research must climb the ladder of eras and is bound by prerequisite dependencies; breakthroughs you develop yourself translate into real returns—battlefield odds, livelihood gains, event mitigations—making "researching tech" a disciplined long-term investment rather than mere number-padding. Technology also gradually **lifts the five-dimensional fog**, laying bare the hidden frailties of state power upon your desk. ② Factional Struggle and the Five-Dimensional Verdict The four powers—imperial clan, scholar-officials, border generals, and merchants—ebb and flow under your rule (−100~100), and each civilization carries its own factional setup (Rome's Senate and legions, Britain's Crown and gentry, and so on). Yet a reign's merits and faults are ultimately judged by the historiographers across five dimensions—treasury, popular will, military strength, court, and livelihood. There is no single victory condition—only the hue you leave for the ages. ③ Flags and Causal Gating The echo of your choices is more than numbers: flags truly **gate** what comes after. A clemency you granted in your youth may, decades later, ward off a coup; a broken oath plants the fuse of retribution within the annals. This layer elevates "branching narrative" into a strategic system with memory and consequence, so that every replay leads to a starkly different destiny. Scope: A Historical Sandbox You Can Conquer Again and Again 556 playable sovereigns: from Chinese emperors to the world's rulers of Rome, Britain, America, and Russia—each with independent attributes and opening situations. Over 10,000 historical events: spanning floods, rebellions, factional strife, succession, diplomacy, and other real historical scenes, varying with sovereign and era. An unbroken span of ages: from early states to the early modern world, tech and events unlock by era—every new game is a fresh context. Vast playtime: a single run can span decades of rule; with free exploration and multiple playthroughs, playtime reaches into the hundreds of hours. Modes and freedom: free decision-making, signature paths, and the cultivation fantasy line coexist; the same sovereign in different hands can walk starkly opposite histories. Unique Selling Points Truth as the backbone: historical scrutiny + dual-source data auditing make the simulation hold up to scrutiny. East meets West on one board: few works place Chinese and world sovereigns—Rome, Britain, America, Russia—into the same comparable ruleset to contend. Tech × Faction × Flag narrative: decisions have depth, causes have echoes, and the strategic dimensions interlock layer by layer. Self-consistent narrative: flag-driven plotting gives every choice a lasting echo, not a one-off firework. On AI: Bring Your Own API for the Best Experience Choice of History has a built-in AI-enhanced narrative mode, where a large mode can dynamically generate more immersive events. For the most immersive experience, we strongly recommend you bring your own AI API key—you control your key and your quota; the game merely hands the historical stage to you and the model to perform together. In offline mode, you can still experience the full breadth of built-in historical content and core gameplay. The moment has come—it is your turn!
