Feudums is a moddable Grand Strategy/4X, scaled for 1000s of players per game, following the vibe of '90s cult TBS games like Lords of the Realm • Became most popular upcoming 4X / Grand Strategy @ Tacticon2023! • Free in-progress demo on Steam!

Direct your subjects and build up your cities, your castles, as well as your alliance of bannermen. Will you call your serfs from the fields or spend your coin building a standing army? Do you become a bannerman for another noble or start your own coalition to back up your claim?

Create your unique coat of arms and build your family dynasty by winning traits and titles over multiple generations and branches. Each session is a community-driven narrative which will flow differently than previous games.

Heavily influenced by old-school strategy games like Lords of the Realm, Defender of the Crown or Genesia, early MUSHes, Crusader Kings and classic board games, Feudums is part builder, part strategy, completely moddable and is fully built around its players, with carefully crafted, hand-drawn visual style, contextual music tracks and original melodies.


• Procedurally generated maps, customizable systems and full modding support.
• Dynamic economy and seasons that simulate the complexities of medieval life - from growth, health, migration or labor to war.
• Dual gameplay loop: you lead and develop your noble house through the generations and branches across games - unlocking new traits and opportunities for future descendants - while playing a deep 4X / grand strategy, competing for power over contested territories in each game session.
• Suitable for both hardcore players and for ones with a busy schedule: you can micromanage anything, but you don't have to - if you set the basic directives, your serfs, military companies or feudum administration can run autonomously.
• A rich heraldic system intertwined with your in-game achievements!
• A deep feudal system that allows for vassalage and different oaths between players.
• A fluid diplomatic system, fostering the organic development of player-driven narratives, as everyone works to take control of events and turn them to their advantage,
• Tactical warfare with a detailed battle system, levies, mercenaries, seasonal military campaigns, reinforcements, war plans and attrition - that rewards careful planning and tactical thinking,
• Built for multiplayer in the fair way: you cannot buy any pay to win element at all.
• Will also offer premium content for single-player - with narrative-driven campaigns, skirmishes and sandbox - for multiplayer-averse players or if you're not in the mood to compete with others.
• Heavily customizable & moddable from top to bottom.
• Beautiful, fully hand-drawn visual style & fully original OST.


Feudums' development is meant to be fully transparent. Our demo is always updated when new milestone builds are completed or we have quality of life (QoL) improvements to add. We always invite you to play our early in-development demo and give us some feedback you have afterwards, but please remember, we are pre-early access: many features of the game is not yet available as we continue to plug away on development.

We have recently added several QoL and UX changes, and the ability to form additional fiefs, so you can start building up a petty kingdom while we're working on an in-game advisory system and diplomacy (you can find a FAQ & a helpful community on our discord, several guides, and short "how to" videos on our channel in the meantime). You can watch our recaps on what's new on our Youtube channel. We are still working hard on the game, and as in the past, we will continue to update the demo based on your suggestions, ideas and feedback!

• completely moddable, customizable and adjustable game systems;
• fully working multiplayer ecosystem;
• victory conditions system;
• the Coat of Arms designer - with rich medieval heraldry;
• seasons, weather and day & night cycles
• the economic simulation - with seasons influencing all aspects of medieval life; labor system; seasonal agriculture, player-driven market, the ability to expand and form additional feudums, and so on;
• the basics of warfare - like seasonal military campaigns, levy troops and mercenaries, detailed simulation for battles with multiple participants, or raiding;
• autonomous actors for serfs, military companies and the land administration.

The game will be free to win, meaning the competitive multiplayer gameplay will remain free, and no in-game perks or advantages can be bought for money, only cosmetic flavor (like coat of arms devices, character designs or architectural styles for your buildings) and additional game modes - like private multiplayer or single player campaigns/scenarios.
