Be born anywhere from 10,000 BC to the far future and live one year at a time in a living world of dynasties, migrations, wars and politics. Free, open source, one HTML file. ## Description Tempora is a free, open-source browser life simulator set across roughly twelve thousand years, from 10,000 BC to a far-future era. You choose where and when to be born, then live one year at a time, and can continue through your children, relatives or acquaintances. The world simulates all inhabitants: settlements grow and are abandoned, farming and copper spread on historical dates, migrations shift ancestry, and governments fall or declare wars. Characters have inherited genetics, personality traits, social class, fame and family. Play covers school and careers, marriage and children, courts and inheritance, sports and politics, with communication that changes over eras from letters to phones to social media and neural chat. It runs as a single HTML file that also works offline and installs as an app on phone or desktop; no ads and no account required. ## Original post A life simulator across twelve thousand years.

You live one year at a time and can carry on through your children, relatives or anyone you knew. The world keeps simulating everyone, including people you are not watching. Countries rise and fall, settlements grow into cities, migrations move people and genes, and rulers make and break wars. The game is free and open source, with no ads and no accounts required. It is a single HTML file that also works offline, and on a phone or desktop it installs as an app (the menu offers **Install the app** where your browser allows it). ![The dashboard on a large monitor: who you are on the left, your ancestry, citizenship, faith, marriage customs and culture in the middle, and what is happening right now on the right](assets/screenshot.png) ## Features - **Eleven eras across every country in the world.** About 200 lands, from the Americas and Africa to Oceania, each with its own names, capitals, currencies, population, laws, genes, cities and history in every era. The old combined regions (West Africa, the Levant, the Maghreb and others) are now their real countries, and the start screen groups lands by region. They run from Prehistory (Mesolithic Europe, the Natufians, the Iberomaurusians) through Ancient Egypt, medieval Europe, the World Wars and the digital age to the far future. Every era has its own careers, currency, laws, diseases and events. - **A living world.** Everyone you know lives out their own life. Settlements grow, get renamed and are abandoned. Farming and copper spread across the world on historical dates. Migrations shift ancestry. Governments fall to revolutions, and rulers declare wars. - **Deep characters.** - Genetics you inherit. - An MBTI type and personality traits that shape your odds, relationships and choices. - Social class that you can rise or fall in. - Fame, reputation, pets and a family crest. - **Every part of life.** - School, careers and promotions. - Love, marriage and children. Introduce your children to friends, mentors or a match. - Places to visit: tavern, church, hospital, market, battlefield and palace. - Courts and trials, wills and inheritance disputes, heirlooms. - Sports careers and the Olympics. - Politics: run for office, rule a nation, declare war. - **Communication through time.** Letters become telegrams, then phones, then social media with followers and posts, then neural chat. - **Feedback everywhere.** Every action, event and choice shows exactly how your stats changed.
