Seedship is an absorbing text game of stellar colonization

Love it! 9731 points on the first run. Ocean planet with high gravity and post-singular civilization, but corrupt democracy… I guess it´s a win…


It was so life like.


I am reminded of John Brunner’s 1991 novel A Maze of Stars, in which the protagonist – an artificially intelligent spaceship – revisits planets which it previously seeded with human colonies.

Brunner uses this device to describe how different environmental conditions lead to different social structures.

Not my very favorite Brunner novel, but well-crafted, and quite Brunnerian.


I am happy to report that this game includes the option to “submit to the tentacles.” This post should get a CEPHALOPODS tag.


I really like this. Makes me want to expand on it, I wish the code was available.

reminds me of (a very brief summary of) Aurora.

So it’s sort of like the Myst novels.


9937 on the first run-through. Not bad.

The whole thing could be used as a good “setting” inspiration for a space themed tabletop game, or as a writing prompt for a short story.



The colonists lay the foundation of a democracy, but it proves vulnerable to corruption and wealthy individuals become a de facto ruling class.

My planet had “outstanding ugliness” as a feature. :frowning:

The front-end seems to use “SugarCube (v2.12.1): A free (gratis and libre) story format, based on TiddlyWiki”

That could be interesting.

Wait, do I want them to be happy?

They live lives of peace and spiritual fulfilment beyond the dreams of their ancestors on Earth, guided by a combination of human and alien philosophy.

Took a few plays, but I broke 11,000. I think I’d need to find natives to get much higher.

Planet El Dorado
Atmosphere: Breathable
Features: Plant life High-tech ruins
Gravity: Moderate
Temperature: Moderate
Water: Planet-wide ocean
Resources: Rich

El Dorado’s ocean stretches to the horizon a blue sky. The colonists live in high-tech cities beneath the planet’s open sky, on platforms floating on the planet-wide ocean. They spend their time pursuing art, leisure, and spiritual fulfilment, while automatic machines take care of their material needs. In the first city stand monuments to the 25 colonists who did not survive the journey, the 62 more who died building the first settlement, and the seedship AI that guided humanity to its new home.

I think if your world is mostly yellow but you have some green stuff on your moon you’ll be OK.

post singularity is achievable with high tech ruins, I assume?

It’s kind of frustrating to have to make major decisions without more data. I founded a colony on a world that was already inhabited by intelligent, largely altruistic beings but the AI never even established whether they were edible or not.
