History VideoGame / KittensGame

* WingedUnicorn: Alicorns are unlocked by higher-tier religious buildings, and are sent back to their dimension in exchange for crystals that boost your NewGamePlus.

* PlanetDestroyer: The USS Mining Vessel Hissmeowra, appropriately called a "Planet Cracker" is stated to be capable of, well, cracking an entire planet.

** Completing the Black Sky ChallengeRun improves Markers by 10% -- their corruption factor will increase from .00001% to .0001%, and they will increase leviathan energy cap by 5.5 instead of 5. This is explained exactly ''nowhere''. The corruption factor increase is at least reflected in the tooltip, but the energy cap isn't mentioned at all.

** The "Winter Has Come" challenge. In the early game, getting a sufficient catnip production is extremely difficult due to the permanent winter and subsequent catnip production cuts. Once you research Aqueducts and better farming tools, all it will take are a few farmers to outgrow the production from catnip fields and offset the catnip demand, pretty much defeating most of the difficulty altogether.

** The "Super Unethical Climax" achievement is awarded to players who click the catnip-gathering button 2,500 consecutive times without 2.5 seconds ever passing between clicks -- i.e, [[NoFairCheating using an autoclicker]].

** The [[{{Transhuman}} Transkittenism]] policy, which prevents the [[AIIsACrapshoot AI Apocalypse]], cannot be enacted if the apocalypse has already begun.

* LeetLingo: Having exactly 1337 of any resource causes the number to change to a different font and display as green on a black background.

* LuckySeven: Having exactly 777 of any resource causes the number to flash yellow.

* FourTwentyBlazeIt: Having exactly 420 of any resource causes it to flash rainbow colors.

* LuckySeven: Having exactly 777 of any resource causes it to flash yellow.

* NumberOfTheBeast: Having exactly 666 of any resource causes it to flash red.

* BadFuture: Once you hit [[TabletopGame/Warhammer40K the year 40,000]], whether naturally or more likely by [[TimeDilation fast-forwarding]], the black hole at the center of the solar system starts having some ''interesting'' effects. While you can take advantage of this and adapt to get more energy and lots more storage, all the time shenanigans get progressively harder the further you go. It's been confirmed this is in place to prevent TimeTravelForFunAndProfit being abused endlessly.

* SnakePeople: Nagas are one of the races that you can trade with. They're neither friendly nor hostile, and they sell minerals in exchange for Ivory. In order to discover them, you'll need enough current Culture when sending explorers.
* SpidersAreScary: Inverted. Spiders are one of the races who can trade with your kittens and they even find your kittens cute, giving them extra resources sometimes.

* BadFuture: Once you hit [[TabletopGame/Warhammer40K the year 40,000]], whether naturally or more likely by [[TimeDilation fast-forwarding]], it's implied the universe starts falling apart. While you can take advantage of this and adapt to get more energy and lots more storage, all the time shenanigans get progressively harder the further you go. It's been confirmed this is in place to prevent TimeTravelForFunAndProfit being abused endlessly.

* VideoGameCrueltyPotential: You also get achievements for having 10 kittens die on you and another for letting 100 kittens die on you.

* YouRequireMoreVespeneGas: There are well over 20 different kinds of resources to hoard and use, whether obtained by workers, hunts, buildings, or trade. And that's leaving out the [[RefiningResources crafted resources]]...

* NumberOfTheBeast: Having exactly 420 of any resource causes it to flash red.

* EasterEgg: Having exactly [[FourTwentyBlazeIt 420]], [[TheNumberOfTheBeast 666]], [[LuckySeven 777]], or [[LeetLingo 1337]] of a resource will cause the number to glow in a different color.

* PowerUpLetdown: Some upgrades are available and affordable a long time before the stuff they affect is actually available or practical -
** Calciner upgrades are plentiful as you move through modern tech. Problem is, Calciners cost expensive Blueprints, so you're not likely to have more than a handful of them until much much later.
** Distant planets, past T-minus, can be explored by just building up your space resources. Unfortunately, they take a long time to reach, there might not be anything you can build there if you didn't get some corresponding research, said research and buildings usually require rarer end-game resources, and even then some are questionably useful - particularly the Hydroponics, which boosts catnip storage and production, long long after you need either of them.
** The earliest time technology is available with just a few time crystals, but its initial effects on your game are very small. Your first impression will be that you just wasted your precious and hard to earn crystals.

** One rare resource is called [[Webcomic/ProblemSleuth Black Liquid Sorrow]].

* TechTree: An almost VideoGame/{{Civilization}} worthy example that starts at inventing the calendar and farming, and ends with space exploration, time manipulation, and antimatter.

-->--Opening log message

* ShoutOut: Several --

** Get to [[TabletopGame/{{Warhammer40000}} 40k years]] and the Dark Future starts. There's also an achievement called "Cathammer 40k" with the FlavorText "In the grim and dark future of a catkind there are no resets".

* MutuallyExclusivePowerups: Policies come in sets, and you can only enact one from each set -- either "Liberty" or "Tradition", but not both. This is marked by the policies in a set having the same numeric cost.

* TheArtifact: Black Liquid Sorrow is measured in percentage points. It's not actually a percentage of anything now, but in older builds, having BLS would provide a production boost.
