What if the Library of Alexandria survived? What if the South won Gettysburg? What if the Soviet Union never collapsed? Choose a famous What If, and watch realistic consequences cascade across politics, economics, military, culture, and technology over decades. Every simulation is grounded in actual history — not fantasy. Built for history enthusiasts, students, and strategy gamers who want more than a Wikipedia rabbit hole. ## What's included - **200+ pre-built scenarios** — Library of Alexandria survives, Mongols don't withdraw 1242, Spanish Armada wins 1588, Napoleon wins Waterloo, Confederacy wins Gettysburg, Tsar Alexander II not assassinated, Germany wins WWI, Hitler dies 1923, Japan doesn't attack Pearl Harbor, Cuban Missile Crisis goes hot, Soviet Union doesn't collapse, 9/11 prevented - **Cascading consequences** — political (regime changes, alliance shifts), economic (trade routes, currency dominance, industrial revolution timing), military (technology development, balance of power), cultural (religious distribution, language spread, art movements), technological (printing press timing, industrial revolution location, atomic age delay) - **Decade-by-decade timeline** — runs simulation 10/25/50/100+ years forward with branching events; tracks butterfly effects (small changes → large consequences) realistically - **Play-as-figure mode** — be Napoleon at Waterloo, Lincoln at Gettysburg, Stalin in 1953, Kennedy in 1962; constrained by what that person actually knew + believed at that time; agent enforces period-appropriate constraints - **Custom scenarios** — describe your own "what if" → agent maps the change, identifies cascade triggers, runs the simulation - **Counterfactual rigor** — flags when alternatives become implausible (e.g., "Aztecs developing steel by 1500" requires multiple unrelated changes); rates plausibility of branch points - **Source grounding** — cites the actual historical evidence each cascade builds from; you can drill into "why would this lead to that?" - **Discussion prompts** — for classrooms / book clubs: "What does this scenario reveal about path dependence?" / "Which modern parallels does this surface?" ## Limitations - **Not a peer-reviewed historical paper** — speculative counterfactual; rigorous about plausibility but not academic publication quality - **Not a strategy game** — scenarios run as narrative simulations; pairs with paradox-style games (CK3, EU4, HoI4) for actual play - **Not a divination tool** — alternate histories are speculative by definition; "would have" claims are calibrated probability, not certainty - **English-language sources** — non-English historiography under-represented; agent flags when this matters - **Modern-history-focused** — pre-Roman + non-Western histories thinner than European + American ## Best fit History enthusiasts who finished the obvious books + want to think harder. High school + college history students exploring counterfactual reasoning. Strategy gamers wanting deeper historical grounding for paradox-style campaigns. Writers + worldbuilders developing alternate-history fiction (Man in the High Castle, 11/22/63, Years of Rice and Salt territory). Especially valuable for the post-Wikipedia phase — when you understand WHAT happened but want to explore WHY it mattered + what almost didn't.
