History YMMV / LuigisMansion3

** Amadeus Wolfgeist manages to make The Great Stage a truly [[{{Pun}} great stage]]. His fight has two phases before he even attacks directly, and then he leaps into his piano to possess it like ''Dark Moon'''s bosses. From that point on, it's a surprisingly challenging fight as the piano attacks and you have to perform several steps to get Wolfgeist out of it so you can attack, which can be jarring at first, but turns out to be a really fun challenge. As a bonus, Wolfgeist serves his purpose as a pianist by [[LeftTheBackgroundMusicOn providing music for the encounter]], including the frenzied ghost-catching theme.
** The other climax bosses guarding the paintings (Ug and Captain Fishook) are pretty fun, too, also borrowing from ''Dark Moon'''s formula very well.
*** To elaborate on both, Ug starts the fight possessing a freaking ''T-Rex skeleton''! You have to frantically wait for him to drop eggs for you to fire into his mouth and after you do, he wises up and destroys one. You then have to use Gooigi in a creative way, get him stuck in the T-Rex's mouth. As for Captain Fishook, he takes it up a notch and possesses the ship you are fighting on. From there, you have to fire bombs thrown by other ghosts into his exposed mouth. Every time you land a hit, Fishook will possess the wall and tip the boat towards him and you have to use the suction shot to hold onto the other side in order to keep from falling in.

* CrossesTheLineTwice: [[spoiler:The Luxury Suite showcases Hellen’s [[LoonyFan obsession]] with King Boo as being to the point of being a StalkerShrine. Everything from the statues, to the furniture, to the carpets, to even Hellen’s slippers is in the image of King Boo. It’s so absurd and creepy that it ends up being funny.]]

--> '''Morty''': I didn't notice until now, but your face... It has some nice features! And your build... Not bad. Not bad at all!

* SugarWiki/VisualEffectsOfAwesome: The animation and visuals are [[IncrediblyLamePun ab-soul-utely]] spot on, with many people noting that Luigi's design is ludicrously detailed, from the stitches on the L on his cap to his overalls having polyester similar to ''VideoGame/SuperMarioOdyssey''. The animation itself has gotten a fair amount of praise too, with many claiming that it looks close to a film made by Creator/{{Pixar}}. The game also has complex dynamic lighting and tons of interactive objects with full physics in each room, and overall completely outclasses the original and even the ''Dark Moon'' art direction it's built on. Many reviews of the game were quick to call it one of the best-looking titles on the Switch, which already has games noted for their visuals.

** Serpci gets this for her EvilIsSexy design, her BestLevelEver pyramid, and her SandBlaster (a popular SwissArmySuperpower in fiction) skillset.

* EvilIsSexy:
** Hellen Gravely, part of the BigBadDuumvirate, is fairly easy on the eyes for a female ghost in her middle age. [[spoiler:When she isn't pissed.]]
** Serpci looks ''just'' like how you would expect a pharaoh queen to be as a ghost.
** Amadeus Wolfgeist has garnered quite the EstrogenBrigade thanks to his elegant appearance and personality.

* AntiClimaxBoss:
** After the challenging and puzzling but fairly enjoyable Hellen Gravely penultimate boss fight immediately beforehand, King Boo makes for a somewhat disappointing FinalBoss. It's a fairly straightforward "FeedItABomb [[RuleOfThree Three Times]]" boss battle that is more [[GoddamnedBoss frustrating]] than challenging, stemming from the difficulty in aiming the bomb in King Boo's mouth. Even with King Boo spawning decoys and introducing harder attack patterns in each stage, it still ends up feeling repetitive as you're just waiting for King Boo to perform the same attacks until bombs spawn; unlike ''Dark Moon'', there are no chase sequences to break up the battle and spice things up. Not even the [[TimeLimitBoss time limit]] is enough to make it feel climactic, since there's no NonStandardGameOver for letting time run out.
** Polterkitty can be reduced to a ZeroEffortBoss by the fact that during the part where you let her creep up behind Luigi, she [[ArtificialStupidity won't notice Gooigi]] in the room until he flashes her before she's about to pounce. This means that while Polterkitty sneaks up on Luigi getting ready to pounce, you can have Gooigi sneak up on ''her'' getting ready to flash.

* CompleteMonster: King Boo. See [[YMMV/LuigisMansion here]] for details.

* UnderusedGameMechanic: Super Suction, for being a satisfyingly destructive powerup and requiring an entire EscortMission to obtain it, is introduced late in the game and only has three places where it can be used. Only one of those is tied to progression through the game, with the other two merely opening up puzzles for collectibles.

* AngstWhatAngst: While being trapped [[AndIMustScream within a painting]] is definitely a terrible fate, Luigi's friends don't seem all that bothered or affected by it at all when they are let out, returning to their perfectly bubbly and cheery selves once freed. In fairness, it's suggested in the second game that characters aren't fully conscious or aware of the passage of time while in the portraits. [[note]]With the exception of the original game, in which Mario is fully animate in his portrait and can even speak, but that idea that didn't carry over into the rest of the series.[[/note]]

* ImprovedSecondAttempt: Most of the Portrait Ghosts in the first game never actually attempted to harm Luigi unless ''he'' provoked them, which made the ghosts come across more like [[DesignatedVillain Designated Villains]]. Here, the ghosts are genuinely malicious and purposely try to kill Luigi even if he doesn't mean to bother them. The only ghost that isn't antagonistic is Morty; capturing him is made completely optional.

** Did [[CowardlySidekick Luigi]] [[ProperlyParanoid suspect that King Boo had planned a trap for him from the very beginning of the game]]? Notice how Luigi acts in the intro: unlike Mario, Peach, and the Toads, who are chatting and enjoying the bus ride, he's asleep. His only luggage is a flashlight and a book, which he doesn't seem very interested in, as when he tries to read it, he immediately conks out. When the gang arrives at the hotel, he's the last person to enter the building, and when he does enter, he's not as excited as the others, to the point where he's cautious toward Hellen Gravely (as indicated by him sneezing at the scent of her perfume). And in general, his attitude toward the whole thing doesn't exactly look like the sort of reaction anyone else would have to, you know, winning a free ride to a big hotel that promises lots of money, fun, and adventure. It's almost as if he suspects ''something'' is wrong...but being [[NiceGuy Luigi]], he can't put his finger on what the problem is, or doesn't want to worry his friends about it. Then again, [[VideoGame/LuigisMansion the last time Luigi got an invitation to a big, rich place full of money and treasure all around...]]

* CompleteMonster: King Boo. See [[YMMV/LuigisMansionSeries here]] for details.

%% Please look at the more stringent requirements for NightmareFuel before adding, and run by the cleanup thread if you're not sure.

** Serpci is uncharacteristically strong for a boss that doesn't guard a painting, featuring some nasty moves and requiring the player to get up close, where she is arguably even tougher.

** Clem is infamous for stumping many players, but mostly because of FakeDifficulty. The tube riding controls are not the most intuitive, which makes navigating through the endless mines and spiked walls a frustrating experience, and in order to make Clem vulnerable in the first place, you ''need'' to let him get close enough to attempt to whack you (but not let yourself get whacked, which, again, is very troublesome due to the aforementioned controls). If you do manage to put Clem into a stunned state (either due to the dodging strategy or luck from a stray mine), you still have to chase after him when he's spinning around uncontrollably, catch his tube, shoot it into the spikes ''and'' chase after him again when he lands outside the pool. Overall, it's a boss with a simple logic behind it, but with plenty of steps and annoyances that are not immediately obvious about how to perform or overcome. The saving grace of this fight are the endless rats that provide health if vacuumed, so you can afford to get hurt and pop your tube repeatedly, but inflating a new rubber floatie is still an annoying process thanks to Luigi being unable to move until he finishes doing so.

** Serpci is uncharacteristically strong for a boss that doesn't guard a painting, featuring some nasty moves and requiring the player to get up close, where they have a high chance of becoming sand snake food.

* FridgeBrilliance:
** All of the themed floors in the mansion seem appropriate to the setting of a haunted hotel (the pirate-themed restaurant has a ghost ship and the desert suites are themed around pyramid tombs, after all) except the dance hall... until you realize it's disco-themed. Ever heard the phrase "[[DiscoSucks as dead as disco]]"? That would adequately describe the clientele for this floor. The dancers also perform a synchronized dab move, which might invoke the idea of it being a dead meme.
** Chambrea is kind of annoying, since you have to chase her around the floor, interrupted each time she moves... but it makes perfect sense that the location of a fight against a maid would be ''multiple guest rooms'', since going from room to room is how maids do their job, and it ties perfectly into the classic trope of ghosts going through walls.
** How exactly did Hellen Gravely bust King Boo out of containment? [[AbsentMindedProfessor E. Gadd]] obviously forgot to get rid of the "Release Boos" button seen at the end of VideoGame/LuigisMansionDarkMoon.
** When the Mario Bros. reach the roof of the hotel where Peach's portrait is, Mario absolutely ''panics'' upon seeing what happened to Peach. Seeing how Peach is kidnapped [[OnceAnEpisode every other week]], this should be no big deal, so why is Mario panicking now? Because for once, there is ''nothing'' he can do to save her, but Luigi can, and that's why he frantically begs Luigi to help her. In addition, Mario knows that when Bowser kidnaps Peach, he at least knows that [[NeverHurtAnInnocent Bowser would only hurt her]] [[VideoGame/SuperPrincessPeach if she directly]] [[VideoGame/SuperMario3DWorld interferes with his plans]] [[VideoGame/PaperMarioColorSplash or Bowser isn't himself]]. King Boo, being TheUnfettered and with a hateful grudge, probably ''would'' hurt Peach if it was what it took for him to win.
** Most Boos, including King Boo himself in ''[[VideoGame/LuigisMansionDarkMoon Dark Moon]]'', stop moving and hide their face when the player approaches them. But in this game, King Boo never hides his face, not even during his boss battle. He's so pissed off at Luigi continuously foiling his plans that he managed to get over the inherent shyness of his kind.
** E. Gadd states in his [[AllThereInTheManual research journal]], after the web page showcasing it is updated for ''Luigi's Mansion 3'', that the ghosts of the original ''VideoGame/LuigisMansion'' have an energy that's "structurally different" than that of the Evershade Valley ghosts of ''[[VideoGame/LuigisMansionDarkMoon Dark Moon]]''. This is to be expected, actually, given the ghosts from the first game were [[MookMaker creations of Vincent Van Gore]].
** While it may seem unnecessary that the elevator buttons magically screw themselves into their proper sockets every time Luigi tries to install one, this is obviously some sort of foresight on ''someone's'' part, be it King Boo, Hellen Gravely, or even the ghost minions responsible for snatching the buttons in the first place, to prevent [[LoopholeAbuse Luigi from just screwing the button into the 15th floor's socket]], [[DungeonBypass and thus immediately reaching Hellen Gravely's room]].
** The hotel is called the ''[[MeaningfulName Last Resort]]'', and in the final bossfight, King Boo decides to just make a huge painting to trap everyone in the hotel in a last-ditch attempt to kill Luigi. It's his last resort.
* FridgeHorror:
** King Boo imprisons Luigi in a painting when you get a {{game over}}, even in cases where [[NotEnoughToBury there wouldn't be any Luigi left]], such as the spiked wall trap in Castle [=MacFrights=] and the ceiling traps in Tomb Suites. So does King Boo frame Luigi's ghost?
** If you slam ghosts to 0 health, they just explode into orbs of light that disappear. Are they DeaderThanDead? Even worse if you subscribe to the interpretation that they were brainwashed by King Boo's crown gem.
** Let's hope Gadd puts every countermeasure he and Luigi can think of on King Boo's container, because considering he gets more and more psychotic with each game because of {{Villainous Breakdown}}s, if he gets out again, he'll be absolutely ''feral''.

** Polterkitty is considered to be such an [[GoddamnedBoss annoying boss]], that after spending minutes — perhaps even ''hours'' — going floor to floor trying to retrieve the elevator button she swallows, it can be quite satisfying to see her get sucked up ''once and for all'' the second time around. Not going through the ordeal again for the rest of the game.
*** This is potentially even more satisfying for those who have played ''VideoGame/LuigisMansionDarkMoon''. In that game, Polterpup (who served a similar role to Polterkitty) gets fully sucked into the Poltergust numerous times, but repeatedly breaks out of the ghost gallery until it's repaired and made secure. Here, when defeating Polterkitty the first time, she isn't sucked in, but rather coughs up the elevator button and flees. Thus, when you see her actually vacuumed up the second time around, you know that she's gone for good.
