Watch a galaxy come alive.

Galaxization · Official trailer

01 · What it is

Your wallpaper is a galaxy of 200,000 stars, and on one of its worlds, someone has just begun to think.

Galaxization is a galaxy and civilization simulator that runs as your Windows desktop wallpaper. Behind your icons a procedurally generated galaxy slowly turns, and every day your PC is on, about two million years of its history go by: a first species leaves its homeworld and splits into rival nations that trade, found religions, go to war, build wonders, collapse and climb back.

It is a game you watch. No two galaxies share a history. Each happens once, and you are its only witness.

02 · What you do

Leave it running. Fly in when you like.

The galaxy on a wallpaper, with the year and the age at the top right and the newest log line below

Leave it running.

Glance up between tasks: the wallpaper shows the year, the name of the age and the newest line of the observatory’s log. Something worth reading happens about every half hour.

Sunset over the dunes of a living world, under a sky full of stars

Fly in.

Ctrl+Alt+G turns the wallpaper into a place you can move through: from the whole galaxy into any of 5,000 star systems, down to a planet, and onto its surface to watch the sun cross the sky.

A spiral galaxy divided among named civilizations, beside the chronicle listing their history

Read its history.

Every civilization has a file: its character, its neighbours, what it has learned, what it believes, and its own chronicle since its founding.

03 · It stays out of your way

It stays out of your way.

Under 1% CPU on the desktop, on integrated graphics. It stops drawing when a maximized window or a full-screen game covers it, and the history carries on. Silent by default.

  • Main screen · your wallpaper
  • Second screen · observatory console

  • Light at rest

    10 frames a second and under 1% CPU while nothing moves; a few hundred MB of memory.

  • Covered, it stops

    A maximized window or a full-screen app stops the drawing. The history carries on.

  • A second screen

    Connect a second monitor and it becomes the observatory console.

  • An orchestral score

    Silent on the desktop by default. Go in and an orchestral score plays.

  • Local mods

    Local mods are supported. The game itself stays offline; achievements and cloud saves go through Steam.

  • Four languages

    English, 繁體中文, 简体中文 and 日本語.

04 · Astronomy and science fiction

Real astronomy. Science fiction, on its own.

There is usually one native species. Once it leaves its homeworld, it splits into rival nations; a quarter of galaxies have two species.

Astronomy

A galaxy built on real astronomy.

Seven kinds of galaxy, a ray-traced black hole at the centre, planetary systems worked out from their star, and life that follows its chemistry.

Science fiction

Science fiction, happening on its own.

A sky where being heard is dangerous. Generation ships at a tenth of the speed of light. Machines that wake. Dyson swarms that take hundreds of thousands of years: a few hours of your time.

  • Planets from their star

    Habitable zones, snow lines, multiple stars, white dwarfs and tidally locked worlds.

  • Life that follows chemistry

    Carbon in water, silicon in sulfuric acid, life in methane lakes at 90 K. Most habitable worlds hold no life, or only microbes.

  • Watched in secret

    An ancient civilization may watch a young one in secret for a hundred thousand years.

  • History with causes

    124 technologies, 17 doctrines, 103 schools of thought and 15 wonders; machine minds, uploads and choirs.

06 · Once

One galaxy, once.

No seed to type and nothing to replay. When you are ready, order a jump to another galaxy; the old one is ranked and sealed in the Archive of Galaxies. Nine endings, deliberately rare: most galaxies never reach one.

The Hall of Sightings keeps the rarest things you’ve seen, across every galaxy you watch.

07 · Who it’s for

Who it was made for.

If you leave nature documentaries running, lose evenings to timelines of the far future, or have stood outside at night doing the arithmetic on how many of those stars have planets, it was made for you. If you would rather command the fleet, this is not that game.

08 · The story

You are the technician who reads its reports.

Millions of years from now, humanity travels the universe freely. Passing this galaxy, we sensed that life here might be on its way to thought, as we once were.

So we left an observatory at its edge, an observation AI to keep it, and its orders: watch, record, report, never interfere. You are the technician who reads its reports.

  1. 01Watch.
  2. 02Record.
  3. 03Report.
  4. 04Never interfere.
