'''''SEED DEPLOYED TO TROPERIFFIC CLUSTER 22-58'''''

'''''ESTIMATED TIME UNTIL ARRIVAL: 0 YEARS'''''

''Spacebase DF-9'' is a ''VideoGame/DwarfFortress''-esque sci-fi SpaceManagementGame by Creator/DoubleFine. Originally conceived as a prototype during the company's 2012 Amnesia Fortnight, this standalone version, released on UsefulNotes/{{Steam}}'s Early Access program in mid-October 2013, expands on the prototype in ways such as an isometric perspective, more detailed character sprites, more environmental hazards and so on.

The story starts after a massive galaxy-wide socio-economic collapse, where a plan to recolonize the galaxy is put in motion. The idea is that multitudes of "seed" units are sent to various points in the galaxy to start construction of various residential outposts. You take on the role of looking after one of these seed crews, assigning them tasks and making sure they're kept safe against various hazards, be it pirate-related, or a meteor shower, or a sudden influx of space-parasites.

!!''Spacebase DF-9'' contains examples of:

* AsteroidMiner: Your primary means of income as of Alpha 1.
** In the amnesia fortnight version you could destroy asteroids with your mouse (also for income).
* ArtEvolution: Compared to the original Amnesia Fortnight prototype.
* ArtificialStupidity: As of Alpha 1b, low-skilled technicians can subtract from the damage percentage of an object just as often as they can add to it. Cue exploding oxygen recyclers and a lot of frustration. Thankfully, this particular issue was fixed in Alpha 2.
* CharacterBlog: Each resident has a "[=SpaceFace=]" feed to give an insight into their lives and feelings.
* CrapsackWorld: The entire galaxy. Hence the attempts at recolonization.
* DarkerAndEdgier: The unofficial patch by Derelict games converts the game's tone to this. The villain is switched out from "Pirate Megafleet" to "Malevolent Dictator of the Galaxy and his (extremely large) army", it turns your security guards murderous (kills civilians who break down into a tantrum instead of just incapacitating them, no questions asked), and introduces raiders who try to trick you into letting them approach your base. Also, lots of gratuitous body horror in the text description.
* DefeatMeansFriendship: Potentially, anyway. The prerequisites are that you have a brig zoned, a few citizens as doctors, and your security policy set to Non-Lethal. With that, once raiders board your space station, if you act fast to assign a brig to the raider(s) after incapacitating them, they will eventually pull a HeelFaceTurn and integrate into your base as useful crew after a stint in the brig.
* FutureFoodIsArtificial: Food replicators change matter into mediocre food, while there's the option to grow organic food on board your station for serving in pubs.
* GameMod: After abandoning the game, Doublefine released the source code under an extremely liberal license and the result was...
** A group calling themselves "Derelict Games" have added onto the game by modifying the source code itself. An "Officially Unofficial Version 1.7" has been released and a bugfix patch afterwords titled 1.7.1. The group has a roadmap on their website detailing the direction they wish to take the game, though as of 2016 the group appears to be inactive. A final update- version 1.08.1 - was pushed out by the group in 2018 before officially disbanding. However, with that move they uploaded their code to [=GitLab=] so aspiring modders can fork the mod and continue their legacy.
* GodMode: Debug mode. Activating it also activates a plethora of cheat keys you can use.
* ImAHumanitarian: Corpses (from dead colonists and raiders) get recycled into matter. Food replicators consume matter when used. It's literal FridgeHorror when you make the connection.
* IsometricProjection: As opposed to the top-down perspective of the Amnesia Fortnight prototype.
* LostColony: Derelicts--empty bases that occasionally show up nearby--which may or may not contain hostile lifeforms hell-bent on attacking any security staff you send their way.
* KillerRobot: As of Alpha 2, derelicts can be infested with these.
* MoraleMechanic
* NintendoHard: Building a base that can accommodate at least six people within the first 8-minute period, and still having enough for a refinery room when you're done (assuming you didn't run out of time and the builders all die first). Then the raiders start showing up even before you have enough matter to have a brig built or enough staff to form a security squad, and it's unforgiving.
* NobodyPoops: Seriously, there's no option to building ''johns'' in your space station. No wonder they all become grouchy fast!
* OxygenMeter: Entering space (While wearing a suit, obviously) gives a resident around 8 minutes of time before they have to return to the airlock to resupply.
* PlanetOfHats: There are already entire races of frog and chicken people living alongside humanity as of Alpha 1.
* ShoutOut:
** "DF-9" is a triple pun: not only does it reference the fact that the game was inspired by "Series/StarTrekDeepSpaceNine" and "VideoGame/DwarfFortress", but it's also an abbreviation of the name of the development company ("Double Fine").
** One possible hazard involves a resident complaining about feeling pregnant ([[MisterSeahorse regardless of gender]]), after which [[{{Film/Alien}} an aggressive alien parasite suddenly bursts out of them]]. In the same vein, one possible name for new citizens is "Ripley".
** Speaking of ''Alien'', one of the types of organic foods, the "Icky Pod", even bears a strong resemblance to a Xenomorph egg.
** the BGM during the map select screen bears heavy resemblance to the opening riff of [[Music/DavidBowie Star Man]].
* SpaceStation: The game is all about building a working (though somewhat doomed) space station with a large number of alien individuals as citizens, and numerous random disasters that you as the player have to deal with.
* SuspiciouslySpecificDenial: One hail transmission goes all out to assure you that the approaching vessel are not filled with pirates and that the transmission is not artificially jammed. [[spoiler: Telling them that you have no resources either causes them to leave you alone, or if you're unlucky, to forcefully attach to your base and raid you]].
* ThrownOutTheAirlock: Can be accomplished by forcibly opening the airlock doors.
* VideoGameCaringPotential: Honestly, you want your base to flourish and grow.
* VideoGameCrueltyPotential: See ThrownOutTheAirlock above. Another popular method is to disable all the oxygen recyclers and watch everyone suffocate to death, or to remove a wall on the station and let the people inside be sucked into space. Or set all your defense turrets to "attack everyone mode" and tell people that they're welcome when they hail. Double Fine made very sure that even the sadists can have fun too.
** Also, [[spoiler: one way to safely tackle derelicts is to order the vaporization of them- not only do you get any hostiles (and innocents) in there sucked into space, those that didn't will die of asphyxiation and eventually get recycled into matter instead. And the derelict itself gets recycled too. A win-win situation.]]
* {{Unobtanium}}: Matter. This wonderful multi-use material can be processed into metal, concrete, wood, cotton, plastic, glass, all forms of semiconductors, food, and even organic lifeforms like plants!
