The Long Reign

A realistic world, down to the last detail.

A civilization game that aims to be fully realistic, rich in every detail, without overwhelming you with decisions. Winning a war doesn't end the story: your civilization goes on.

The Long Reign is a 3D civilization game. What defines it isn't a list of features but an aim: a fully realistic world, rich in every detail, that never turns each detail into a decision for the player. Every building rises piece by piece, with villagers hauling each beam and each stone. Research is done by schoolchildren sitting at their desks, and technology shows up on the map: baskets, wheelbarrows, carts, tools, armor. Buildings evolve through five tiers, from wattle and thatch to brick and stone, and roads form on their own as people come and go. The world has its own weather and seasons, day and night, wind, and real sound instead of music. Its resources are those of a real world: trees, food, stone, gold and crystal. And the final ambition is for that world to be the whole planet.

Realistic, never overwhelming

What defines The Long Reign isn't a list of features but an aim: a fully realistic world, rich in every detail, that never overwhelms you with decisions. These are some of those details.

Lots of detail, few decisions

The world takes care of the small things and you take care of what matters.

Piece-by-piece construction

Every building rises with villagers hauling each beam and each stone. It doesn't pop in: you watch it go up.

Weather and seasons

A full weather system and seasons that pass. Day and night, wind, lanterns lit at dusk and banners in the breeze.

Real resources

Trees, food, stone, gold and crystal. What your people need comes from the world itself.

Research you can see

Science is done by schoolchildren at their desks, and every advance shows up on the map: baskets, wheelbarrows, carts, tools, armor.

Buildings that age with you

Five tiers: wattle and thatch, half-timber, stone, gothic, and brick and stone. Your village grows over time.

Roads that form on their own

Routes appear between buildings and pave themselves as people walk them. You don't have to draw them.

A world the size of a planet

The aim is for the world to be the whole planet. Its final size isn't decided yet.

Winning doesn't end the game

A won war isn't the end. Your civilization goes on, and waits for you exactly where you left it.

Roadmap

  1. The kingdom

    In progress

    The core of the game: villagers who build piece by piece, five building tiers, visible research, weather, seasons, day and night, and its resources: trees, food, stone, gold and crystal.

  2. More realism

    Next

    More detail in every system without adding decisions for the player. A world that behaves like a real one and is still simple to play.

  3. The planet

    Later

    Growing the world toward the final aim: the whole planet.

  4. Platforms

    TBD

    Where it will be played isn't decided yet. It will be announced in the devlogs.
