Familiar ideas from Crusader Kings, in a shared world

Fantasy-Sim is not Crusader Kings, and it is not a grand strategy game. You play one person in a world shared with other players, not a realm seen from above. But if you have played Crusader Kings, some of its ideas will feel familiar.

What will feel familiar

An empty marble throne under an arch, the sea and a white city beyond
  • Your house outlives you. Characters grow old and die. You marry, raise children and name an heir, and your house goes on.
  • Titles and succession. Every country is a kingdom with a crown and a duchy for every region. Titles pass at death, and a vacant crown is filled by the dukes.
  • Claims. Conquest and inheritance give claims, and pressing one is a way to take a title.
  • A council. Every kingdom has a council of twelve that passes its laws.
  • Traits. What your character is born with, and what life does to them.
  • Faith and plague. Three faiths with orders and relics, and epidemics that spread from region to region.

What is different

A village of thatched houses beside a river and a mill wheel, a castle on the hill beyond
  • Every other lord is a player. The king, the dukes, the council and the people you trade with and fight beside are other players.
  • The world never pauses. A day in the world lasts an hour, and it goes on turning while you are away.
  • You are one person in it. You do not command a realm from above. You work, trade, vote, preach and fight as one character, and power comes from the players who stand with you.
  • An economy run by players. Companies, wages, markets and currencies, all in players' hands.
  • A fantasy map. Five kingdoms of five peoples on one drawn island.
  • It runs in your browser, for free. Nothing to install and nothing to buy.
