History YMMV / RainWorld

* TheInverseLawOfFandomLevity: ''RainWorld'' is a game about being a small and vulnerable creature existing as part of an ecosystem that will continue on with or without your participation, where death is both common and unexpected, tinged with an atmosphere or existential horror, more mundane terrors, and meddling in the affairs of crushingly depressed godlike beings. You wouldn't get this assumption by watching the various [[https://www.youtube.com/watch?v=gaiBKECU1xw goofy music videos]], [[https://www.youtube.com/watch?v=SwFq4w0-Mms meme dubs]], and [[https://www.youtube.com/watch?v=jrZhWbkV2CA even more unhinged content]] produced by this fandom.

** Noodleflies are often referred to as "Noots".
** The Artificer's citizen ID drone is nicknamed "Sofanthiel". [[spoiler:This is [[AscendedMeme referenced as the code necessary to play as Enot.]]]]

** Farm Arrays is widely considered one of the ungodliest regions to traverse. Many of its flats have large Worm Grass that require riding Rain Deer to cross. These Rain Deer typically require being fed a Spore Puff to hitch onto their antlers. However, [[GuideDangIt it's not immediately obvious]] that Spore Puffs have this purpose, or how to change their movement prior to the Downpour DLC. Said Rain Deer have also had bouts of ArtificialStupidity in the forms of sitting down or moving in unusual ways. There is a snaking path between all gates that doesn't require the Rain Deer mechanic, but it's riddled with weaker Worm Grass, a careless player can fall off this path into the lower-western room with the Yellow Lizard pack, climbing up junction room LF_D02 requires deft spear placement and platforming, turning back from the gate to Subterranean requires you to ride Rain Deer through two patches before returning to this route, and taking said path between the gate to Outskirts and either of the other gates requires you to pass a Scavenger Toll -- hope you have a good pearl supply or exceptional Scavenger reputation.

* MemeticMolester: [[spoiler: Again, Inv/Enot/??? seems to have been made for this, being shown in-game to attempt [[EpicFail (and fail...miserably)]] to get together with ''all'' of the other main slugcats, with the fandom blowing them up as a desperate, lonely and skeezy lounge lizard who's determined to find ''[[AnythingThatMoves anyone]]'' who'll reciprocate their advances, often shown to [[Main/NoSenseOfPersonalSpace harass the other slugcats excessively.]]]]

* MemeticPsychopath: Artificer's campaign is one of tragedy, loss, grief, and pointless revenge. That being said, the community often simplifies Artificer into an absolute blood-thirsty maniac obsessed with nothing but ruining/ending the scavengers' lives to a comical degree and who shamelessly revels in the violence.

*** One specific creature on the quest is the Aquapede, which is one you can find early on your game, if you know where to look, but also ''the hardest'' to eat, by far. For starters, Aquapedes thrive underwater, whereas Gourmand flounders in it, due to their [[SprintMeter exhaustion mechanic]] where simply throwing one spear immediately tires them, slowing them down and running their oxygen up faster than normal. Aquapedes will also almost ''immediately'' head to their den if speared once, requiring you to burst it down ASAP or waste another cycle to either find another one or try again. Lastly, the very areas they inhabit are tailored to the Aquapede and against Gourmand, often being deep underwater, where Gourmand cannot put their weight and Regurtitate to use, as well as limiting you to only ''one'' weapon as you'll most likely need Bubble Weed to keep yourself under. The only feasible way to win is either having an [[TooAwesomeToUse explosive spear or singularity bomb handy]], or to bait an Aquapede to the surface, where you can then attempt to pelt it with your tools[[note]]Spore Puffs are recommended[[/note]] of choice and pray it either doesn't kill you first or that it dies before it crawls back into its den. Granted, there ''is'' an alternate creature you can eat in place of it... [[FromBadToWorse that being the dreaded]] ''[[BossInMookClothing Red Centipede.]]'' Pick your poison.

* BrokenBase: Many players criticize the game's semi-random enemy placements and punishing death mechanics coming across as FakeDifficulty; the rest appreciate its extreme difficulty, feeling it's appropriate for the creature you play as. All agree that the game's design feels ''very'' old school, which makes it both what its fans like the most about it, and what its detractors hate the most.

* PeripheryDemographic: The game is brutal and unforgiving, and the world it sets up is rich and deep in world-building... which makes it an unexpected hit with pre-teens, with much of that part of the fandom overlapping heavily with [[Literature/WarriorCats Warrior Cats' own]], right down to popular ''Warrior Cats'' animators also creating content for ''Rain World''. Despite the game and it's setting veering heavily into the CrapsackWorld angle, most of the fan content is light-hearted and cute, if oftentimes crossing into BlackComedy territory.

** Since Downpour, the full ensemble of Slugcats are often compared to mercenary classes from ''VideoGame/TeamFortress2''. These vary, but the most agreed-on are Scout & Rivulet for being the speedsters of the bunch; Soldier & Hunter for being relatively basic, yet adept head-on fighters; Demoman & Artificer for being explosive users with an impaired eye; and Heavy & Gourmand for being slow, surprisingly articulate powerhouses.

* {{Fanon}}: Each of the five most prominent Iterators are widely associated with one of the specially-powered Slugcats. [[spoiler:While it's canon that No Significant Harassment has Hunter, Seven Red Suns has Spearmaster, and Looks to the Moon adopts Rivulet; fans often sort Artificer to Five Pebbles due to their shared choleric attitude towards the Scavengers and other creatures that disturb them, and Saint with Sliver of Straw due to the latter terminating herself successfully, with Saint's attuned state being akin to the fabled "Triple Affirmative" that would free all creatures from the great cycle.]]

* DemonicSpiders: With the average hostile creature being extremely dangerous, it should speak volumes about the deadliness of these entries that they stick out as ''particularly'' difficult to deal with.
** King Vultures are faster and tougher Vultures, equipped with ''jet-propelled barbs'' that they shoot out to spear Slugcat. These things fire fast, and being hooked by one is instant death, so the only way to dodge them is to anticipate their firing and jump out of the way.
** The two "red" variants of common predators are [[LightningBruiser the pinnacle of might, brutality, and agility]] amongst their brethren. Thankfully, they never spawn naturally when playing as the Survivor or Monk.
*** Red Centipedes are even tougher versions of Overgrown Centipedes. While the latter are relatively easy to deal with, these guys are ''exceptionally'' quick and relentless, able to chase Slugcat all over the region thanks to their ability to crawl on walls. They're quite clever too, able to use their long bodies to reach and grab Slugcat with frightening precision. Red Centipedes are also heavily armored, meaning each small segment has a single-use shield, making the creature hard to damage or stun. The only way to easily take defeat them is by spearing them with explosive spears or blasting them with Spore Puffs, but that's easier said than done considering how fast they move. These things are so scary that even ''Vultures'' will flee from them, and they've been spotted taking down all sorts of top-level predators without any fear.
*** Red Lizards can tank six spear hits, and have a natural resistance to explosives and pain; they take a lot more damage before being stunned. They're very fast, will follow Slugcat ''everywhere'', and can launch a spit attack that stuns and slows Slugcat upon hit, allowing them to close in for the kill. Stealth isn't even an option either, due to these guys and Caramel Lizards having the best sight out of any lizard in the game- it's very easy for one to spot you from outside the visible game area. They're the ultimate land predator, and nothing can stand up to them aside from Daddy Long Legs and Leviathans. If a Red Lizard spots you, getting away or killing it should be considered a legitimate achievement and is often cited as the toughest thing to do in the entire game.
** Daddy Long Legs are floating, bulbous masses of tentacles and flesh, who blindly flail around the Five Pebbles facility looking for prey. If they hear or feel you, they will pursue you with vicious persistence, flailing their sticky tentacles after you and into spaces the main body can't reach. If they get you, they will not let you go unless you toss a throwable item like a rock or spear at the tentacle, and even then they might just grab you again with another tentacle. They're nigh-unkillable, too, their cores having 200 health.[[note]]The average creature in Rain World only has 2-3 health points, with even the Red creatures having 7-10 pips of health.[[/note]] Stealth is usually the only option to get by them in a timely and safe manner.
** Downpour's Miros Vultures have over 1.5x the health of a King Vulture and sport both the speed and head of a Miros Bird which means getting caught by their jaws is certain death. They lack the King Vulture's harpoons... and instead have an ''explosive blast launcher'' in its place, which will either kill you, or stun you to the point where it catches up and kills you. Unlike other vultures Miros Vultures can and will pursue you through narrower spaces at stupidly fast speeds.
** [[spoiler:There's an even worse kind of lizard called "[[https://rainworld.miraheze.org/wiki/Train_Lizard Train Lizard]]" that's extremely fast, durable (10 health instead of a Red's 6), and deadly; lethally biting every frame even if they miss; and they're highly aggressive. They can be found in the Industrial Complex when playing as the joke character Enot]].

** Farm Arrays is widely considered one of the ungodliest regions to traverse. Many of its flats have large Worm Grass that require riding Rain Deer to cross. These Rain Deer typically require being fed a Spore Puff to hitch onto their antlers. However, [[GuideDangIt it's not immediately obvious]] that Spore Puffs have this purpose, or how to change their movement prior to the Downpour DLC.
