** Sometimes you will come across inexplicably uninhabited Gaia worlds, lush planets that are fully habitable by any organic life. You'll also notice that they have unique names, such as "Pristine Jewel". Many first time players eagerly set up colonies on them without even realizing that said worlds are considered holy sites by a Fallen Empire - and colonizing these planets ''seriously'' pisses them off. They will likely then declare war on you in order to "cleanse" their holy worlds. Not a good thing, considering Fallen Empires are very powerful at the beginning of the game and can easily wipe the floor with you.

** During the First Look video for the [[MegaCorp MegaCorps]] Expansion Pack, one of the developers created what they called a "[[ChurchOfHappyology Scientology Build]]" Empire by creating a MegaCorp Empire with both the "Gospel of the Masses" civic and the "Criminal Heritage" civic. The other one lamented that there'd probably be protesters outside their offices because of this.

** The Shattered Ring origin has a civilization born on the remnants of a {{Precursor|s}} RingWorld. They've lost the technology to construct new rings, and the advanced resources they rely on come from an Arcane Generator left behind by their forerunners.

* ReligionOfEvil: The Fanatic Purifiers of the Spiritualist variety likely follow one of these.

* ANaziByAnyOtherName: [[ExaggeratedTrope Exaggerated]] with [[AbsoluteXenophobe Fanatical Purifiers]] empires. Despite the clear plans to seize world domination and wipe out or enslave a number of nations, for most of its existence, UsefulNotes/NaziGermany pursued an active diplomatic policy and to some degree relied on its Axis allies during the war years. Ideologically, their counterparts here, Fanatical Purifiers, are significantly more radical: they are completely obsessed with their views to the point of [[ScaryDogmaticAliens total fanaticism]], they seek to obtain the widest possible "living space" (which, if they are not stopped, will make up the entire galaxy) as well as to exterminate absolutely all other races without exception, and most importantly - [[HardCodedHostility they will NEVER maintain diplomatic relations with ANY other race]].[[note]] although, they are still able to conclude a truce, in case they cannot immediately carry out their intentions.[[/note]]

** Any AI empire with the [[TheEmpire Hegemonic Imperialists]], [[ProudWarriorRace Honorbound Warriors]], or [[SlaveryIsASpecialKindOfEvil Slaving Despots]] personality can belong to this group, especially if they are much more competitive in terms of fleet power than in terms of technology level.

* ObviousBeta: The initial release fell prey to 'released too early' and 'not tested thoroughly enough' tropes, with three hotfixes coming within a couple weeks from launch day.
** There was a real problem in the late-game with stuttering and general lag, as well as instances where selecting a fleet in the late game of any composition will max out a single CPU while the other cores or threads sit around nearly idle.
** There have been records of bugs with armies being lost to the player should they invade a planet, take control, and then be booted out of the system as a result of another empire taking the planet within the borders. What is worse, those armies show up on the outliner wasting a huge amount of space.
** One of the late game crises could not be properly beaten, as a certain trigger relating to planet health didn't work. Another one constantly purged its own population.
** Evasion being so overpowered that the best fleet composition by far was simple corvettes loaded with as many evasion boosters as possible.
** The HOSTILE FLEET DETECTED bug. Due to a flaw in the way the game reported enemy fleet actions on launch, every single time a fleet in sensor range prepared a jump to anywhere, it spawned a hostile fleet notice. By mid or late game, wars can be quite large endeavors between large alliances, meaning there can be dozens of enemy fleets, each of which spawning a message ''every single time'' they jump. The 1.02 patch cut this down somewhat.
** Colony events, the spice of the mid game, hardly ever fire. Fixes were promised and pushed back in several major patches several times. Nowadays, each new colony is almost guaranteed to generate a (unique for that game) colony event, finally.
** Choosing Sol as your starting system didn't prevent the random galaxy generator from adding a second Sol to the map. This was fixed in a later patch.
** A bug can cause only female portraits to be chosen for leaders instead of having it be a 50/50 chance either way.
** Sector AI couldn't understand how to deal with robotic or enslaved pops.
** Originally, if you created a custom species that started on the special "Earth" option (which is always a Continental planet) but ''didn't'' have Continental Preference as its planet preference, you couldn't ever research Continental Colonization and by extension Ocean Colonization, even if you got a compatible species to settle them with. This locks out two abundant planet types for your entire game. No longer an issue now that Colonization techs have been done away with and replaced with the Habitability mechanic.
** It's possible for an AI Empire to invite you for war against... yourself. This tended to happen with Tributary empires that are released, but then hate you. Rejecting their terms does nothing, accepting their terms seemingly starts a war but actually does nothing, and most importantly, they will keep inviting you to the war declaration over and over. It gets annoying after a while, and makes you wonder if wiping them off the face of the galaxy would finally put a stop to it.
** One endgame crisis exterminated itself by purging its entire population until patch 1.2.3 fixed it.
** The only available Victory Conditions at release were Domination (colonize 40% of the available inhabitable planets) and Conquest (conquer every other Empires under your heels). This effectively shafted Pacifists, as they could not start wars of aggression and by midgame, most of the inhabitable worlds would already be colonized and the only way to expand is either trade for planets (highly unlikely if not outright impossible that they would accept a deal where you come out ahead) or to wage war. Pacifists could still declare war of liberation, but allies and vassals did not count toward Domination either. Heinlein fixed this by adding the Federation victory condition, which requires a Federation to own 60% of the available inhabitable planets -- thanks to the changes to alliances in Heinlein, this meant that allies ''did'' count towards it.
** Portraits from pre-order bonuses could not be used by the randomly generated AI empires. A patch that came out alongside the Plantoids DLC pack was supposed to fix this, but it only worked for the plantoids. Creatures of the Void, Arachnoids, Chirpy, and the Platypus still don't show up.
** The original version of the game slapped a hefty -1000 "Not Diplomatically Relevant" modifier on when attempting to form alliances with empires that were too far away, effectively making it impossible and severely hampering Federation-based gameplay. A later patch replaced this with a scaling "distance" penalty that was much easier to overcome.
** The Cherryh update's massive overhauls to the warfare system were apparently barely playtested before release. The new war exhaustion mechanic in particular made a lot of players very unhappy until Day One mods rebalanced or outright removed it. Also, like so many other updates before, Cherryh wreaked havoc on a great many text messages, especially those unique to Machine Empires, so that only indecipherable strings were shown in their stead.
** The Le Guin's massive overhaul to the economy system also has a lot of problems with bugs: AI being unable to use the new Economy, the ability to make infinite money with market, endgame crises cannot purge pops, and more. It doesn't help that the patch was released only 2-3 weeks before the Christmas break. However, the developers went back to work after their break, and by the time of 2.2.6 beta, the game is now in a pretty good shape.

* SlaveMarket: With the DLC [=MegaCorps=], civilizations can access the Galactic Slave Market. You can still buy pops even if you've outlawed slavery, but they'll be more expensive.

* TheRemnant: One of the empires in the galaxy may have the "Remnants" origin, reflecting its status as a vestige of the previous galactic cycle that not only managed to survive to the present one, but also has ambitions to fight for its place in it.

* TheRemnant: One of the empires in the galaxy may have the "Remnants" origin, which denotes its status as a vestige of the previous galactic cycle that not only managed to survive to the present one, but also has ambitions to fight for primacy in it.

** ** Any AI empire with the [[TheEmpire Hegemonic Imperialists]], [[ProudWarriorRace Honorbound Warriors]], or [[SlaveryIsASpecialKindOfEvil Slaving Despots]] personality can belong to this group, especially if they are much more competitive in terms of fleet power than in terms of technology level.

* TheRemnant: If you meet a spacefaring civilization (or one of its ships) that predates yours, odds are it's one of these. How militaristic it is generally depends on how many planets it still has, with the [[ProudScholarRace Xenophilic Fallen Empire]] having four and the [[SpaceOrcs Marauders]] having zero, but the [[BenevolentPrecursors Curators' Enclaves]] are an exception.

** Any AI empire with the Honorbound Warriors or Slaving Despots personality, especially since their slaves aren't particularly good at research.

* YouCantFightFate: While surveying pulsars, it's possible to find a wrecked ship; studying its logs reveales that it is a wrecked exploration ship from an extragalactic empire called the ''Kohtalo''. Some time later, an identical ''Kohtalo'' will appear and open communications. It's quickly deduced this is likely the same ship from earlier in its timeline, and two options are given: warn the ''Kohtalo'' away from the system where the wreck was discovered or not mention it at all. Regardless of your choice, the ''Kohtalo'' travels to the system and is destroyed, leaving two wrecks behind.

* MulticulturalAlienPlanet: Zig-zagged. There is considerable variation in most species portraits and the Leaders or Planetary population tabs will usually display a wide range of skin/scale/fur colors, but each FTL-empire starts out as a OneWorldOrder whose population all share the same ethical values, including either [[HumansAreDivided human]] empire.[[note]]the second one being a LostColony on Deneb[[/note]] It is possible for populations to change ethics but more likely on colonies than homeworlds. Pre-FTL species are implied to comprise a number of planetary nation-states but become unified after [[TechnologyUplift uplift]], discovering FTL on their own, or [[AlienInvasion invasion]] of course. Further, while it's possible to place multiple species on the same planet, the only way for two species to share the same homeworld is through the "Subterranean Civilization" event chain. The ''Utopia'' DLC introduces a trait (Syncretic Evolution) that lets the player start with a second, dim-witted but strong species on their homeworld to act as menial laborers. The ''First Contact'' DLC introduces empires with the Broken Shackles origin, where the starting planets begins with nine different species, the result of a successful mutiny aboard a slaver ship that subsequently crash-landed upon a planet.

* IOweYouMyLife: On anomaly on a toxic planet can reveal an ancient warship that the planet's atmosphere is slowly corroding away, starting a special project for a construction ship to repair it with new components must be done in a limited time frame. If successful, an onboard AI program will reawaken and relay that it had spent the past 4800-ish years stuck there and that it was only days away from being irrevocably degraded. Sensing that it has new parts from you, it will join your empire out of gratitude for rescuing it as a special Admiral leader along with its ship if you allow it.

* YouAreNotReady: Mutually inclusive to the technological BeefGate, the [[KeeperOfForbiddenKnowledge Keepers of Knowledge]] Fallen Empire is this. Completing too many [[spoiler:dangerous technologies]] will give the keepers a reason to wipe your empire out of the galaxy.

* SpaceClouds: It has a nebulae as a type of star system "terrain," like pulsars or black holes, and the galactic map has several named nebulae that encompass several systems. The upside is that you can harvest resources from a nebula with the proper space station module, the downside is that outside sensors cannot penetrate the nebular cloud, so the only way to see what's in one is by sending in one or more ships. This makes a nebula a natural place to spring an ambush on a fleet moving along the galaxy's Hyperspace Lanes.
