▶  Play free in your browser Stable build on itch.io

Begin in 867 or 1066 and make a life in one of nearly 3,000 named settlements. Work, marry, raise children, win your freedom, trade, scheme, take office, and march to war. When you die, continue through the family you raised, while roughly 65 AI realms and their vassals fight, fracture, vote, and redraw the map around you. Progress your family from the fields to the halls of power.

Live from the bottom up

Persistent local households, regional customs, livelihoods, enterprises, and several hard-won routes to freedom.

Climb into power

Command armies, govern land, bargain with the Estates, enter royal councils, or contend with the Papacy.

Leave a history

Every generation remains in an interactive family tree and a complete, searchable Chronicle.

FAQ

Is Fallowborn really free?

Yes. It is free, and it stays free. No download, no account, no ads. It runs in a browser tab, and tips on Ko-fi are welcome, never expected.

What kind of game is it?

A medieval grand strategy dynasty game played one life at a time. Start as a serf in 867 or 1066, build a household, and guide one family toward power while roughly 65 AI realms fight, fracture, and redraw the map around you.

Do I need to download or install anything?

No. It runs entirely in the browser on desktop or phone. The latest hosted build can prepare offline play after one complete visit, and there is also a stable build on itch.io.

What happens when my character dies?

You continue as an eligible relative, including a child you must raise. The family tree and complete Chronicle preserve the people, choices, wars, property, and ranks that carried the house forward.

Can I play on my phone?

Yes. It runs in a mobile browser, and old hardware is a target, not an afterthought. “It chugs on my 2012 phone” is a genuinely useful bug report.
