History YMMV / PokemonDiamondAndPearl

* JunkRare: Obtaining Spinda in these games can be quite a hassle. While many Pokémon that used to be exclusive to the "swarms" mechanic in the originals have become available in the Grand Underground in the remakes, Spinda is not one of them. To makes things worse, thanks to an incompatibility related to how the games render Spinda's unique spot patterns, it cannot be transferred from Pokémon HOME to ''Brilliant Diamond and Shining Pearl'' or vice-versa, which means that not even obtaining Spinda from a previous generation, Pokémon GO (from which you also can't transfer Spinda to HOME), or the GTS can be used to fill its Pokédex entry. Therefore, the only way to obtain Spinda in BDSP (besides trading) is to wait for it to be the swarming Pokémon of the day. The odds of it being Spinda are 1/28, so it can take weeks for it to appear. All of this for a Pokémon with an awful spread of 60 points on every base stat.

* SeinfeldIsUnfunny: ''Diamond'' and ''Pearl'' were very popular when they came out, for finally introducing online play to the series and for being the flagship ''Pokémon'' games on Nintendo's best-selling console ever. However, as ''Platinum'' improved directly on the original Sinnoh pair and ''[=HeartGold=]'' and ''[=SoulSilver=]'' made a strong case to many fans for being the best games in the series, the original ''Diamond'' and ''Pearl'' gained a reputation of being extremely slow, outdated, and outclassed games, with many people considering them to be among the worst core series games.

** Before ''Brilliant Diamond'' and ''Shining Pearl'' were officially announced in February 2021, [[PopularityPolynomial predictably]], many people started asking for Gen IV remakes after Gen III got its own, especially since there is a notable rivalry between fanbases of those two generations, and ''Omega Ruby and Alpha Sapphire'' actually rescued the Hoenn games from being neglected as a whole ([[SeinfeldIsUnfunny something that struck Gen IV as of late]]) with the improved visuals and game mechanics of Gen VI.

** In the original game, the Veilstone Game Corner's music was touted as [[SugarWiki/AwesomeMusic one of the best in the game]], but after the Game Corner was not only left out of ''[[VideoGame/PokemonRubyAndSapphire Omega Ruby and Alpha Sapphire]]'', but also had no replacement, many fans were worried that the Game Corner's music would go outright unremixed. While the Game Corner is indeed left out, it ''is'' given a suitable replacement in the form of the Metronome Style Shop, carrying over the much-beloved [[VirtualPaperDoll fashion feature]] from Gen VI, and the Style Shop also comes with a remix of the original Veilstone Game Corner music, satisfying fans who were scared to see it go.

** To those that miss Pikachu and Eevee's original cry, an item that allows you to change the music to the DS version once you become Champion also changes their cries from the normal PokemonSpeak they have in most of the game to their original cry (or in Eevee's case, the updated cry it had prior to ''VideoGame/PokemonLetsGoPikachuAndLetsGoEevee''.

* CreepyAwesome: Giratina in ''Platinum'' [[OneSceneWonder only appears near the end of the game]], but boy does it make its scene count, by dragging Cyrus in a nightmarish-shadowy fashion into the Distortion World, its incredibly serene yet unsettling home. On top of a [[HellIsThatNoise deafening scream of a cry]], it is agreed that Giratina is one of the most amazingly-unsettling Pokémon ever.

* SignatureScene: '''The Distortion World''', where the player meets Giratina in ''Platinum''. Between the NightmareFuel of Giratina soaring around with its [[HellIsThatNoise screeching cry]], the absolute lack of any life whatsoever in the area besides yourself, Cynthia, Cyrus, the Lake Guardians, and Giratina, surfing ''up'' a waterfall only for gravity to shift and have you going down again, and finally [[FridgeHorror the very disturbing implications]] of what the place truly is, it's the single most memorable confrontation with a version mascot in Pokémon history.

* CriticalDissonance: Review scores are just as good as one would expect from a main series Pokemon game, and they even won the Global Category of the 2022 Tokyo Game Awards. Meanwhile, fans have been split ever since they saw the

* CriticalDissonance: Review scores are just as good as one would expect from a main series Pokemon game, and they even won the Global Category of the 2022 Tokyo Game Awards. Meanwhile, fans have been split ever since they saw the first trailer, and the aforementioned award was met with considerable backlash.
* FandomRivalry: An internal case with the ''VideoGame/PokemonLegendsArceus'' fanbase. It would be easier to list which players have bought both games than those that have only bought one of them, given ''Brilliant Diamond'' and ''Shining Pearl'' follow the traditional ''Pokémon'' formula while ''Legends: Arceus'' is an attempt of a new take in terms of gameplay (all of this not helped by the fact they were released within a mere two months from each other).

** The cross-generational evolutions were so divisive when they first came out that, aside from Sylveon, it turned off GameFreak from doing anymore for ''four generations'' which even detractors believed was excessive. When they returned in VideoGame/PokemonLegendsArceus (the Sinnoh prequels nonetheless), they were highly acclaimed. Nowadays the majority opinion is that most were very good and a few are still divisive, but worth the ones that were well received.

* GameplayDerailment: While the affection/friendship bonuses are meant to encourage the player to form bonds with their Pokémon, the mechanic is controversial for making the game too easy, ruining certain strategies, and/or simply being annoying. In most games since Generation VI, they've been optional, but not in games, which has instead encouraged players that dislike the mechanic to effectively abuse their Pokémon by using bitter herbs and/or intentionally making them faint to lower friendship and prevent the unwanted effects. Other players resort to wasting turns by throwing a Poké Ball at the opponent whenever the bonuses occur.

** Post-National Dex Fantina rematch. She has Pokémon that are fast (Mismagius, Gengar), annoying (bulky Dusknoir with Confuse Ray, Banette with Cursed Body), and the textbook definition of the B-word (speedy Cursed Body Froslass with Focus Sash, Will-o-Wisp '''and''' Destiny Bond). You will end up spending quite a lot of time swapping around Pokémon to outspeed her or cure your Pokémon of ailment or whatever else that will leave you fuming.

*** The level curve is also roughly the same - which wasn't designed with the Exp. Share in mind. This also means [[ItsEasySoItSucks until the Elite Four, you'll end up outleveling everything]] if you stick to one team.

*** Although minor, the 999,999 currency limit is back.

** Honey Trees. You slather one with honey, wait six hours (And that's six real time hours. Changing the clock on your DS or your Switch for Brilliant Diamond and Shining Pearl players won't have any effect), and a wild Pokémon appears for you to catch. It's often a Wurmple, which you don't need Honey Trees to find, unlike ''every other Pokémon'' that can appear. If you're not satisfied with what you get, SaveScumming will only change the level, nature, gender, and [=IVs=] (though this is helpful with Burmy and Combee, as the former evolves into different Pokémon depending on gender and the latter ''won't evolve at all'' unless it's the uncommon female). There's a 10% chance that nothing will appear.

** Fire Fang hits through Wonder Guard due to an oversight.

* ScrappyWeapon: In both gameplay and competitive battles, the HM move Defog. In-game, it's used to remove fog (a field effect that lowers the accuracy of nearly every move used in battle) in the field in addition to lowering the opponent's evasion by one stage. The fog itself is viewed as a totally unnecessary and frustrating weather effect designed to waste a valuable move space on your Flying-type [[ClosestThingWeGot or Pokémon with wing-like appendages]] for the sake of having an even number of [=HMs=]. Besides, most Flying-type Pokémon can learn Aerial Ace to bypass the fog's effect. It can remove your opponent's Light Screen/Reflect, but it will also remove ''entry hazards that you placed'', making it counterproductive in competitive singles (where entry hazards are extremely important). It was eventually [[RescuedFromTheScrappyHeap salvaged]] in ''X and Y'' when it was made so that it also removes entry hazards placed by the opponent, making it a competitive staple since it can't be blocked like Rapid Spin (the only other way to remove entry hazards).

** While still a bit of a hassle, catching Spiritomb has become much more feasible. It's no longer necessary to talk to 32 other players; instead, you have to interact with 32 different NPCs that spawn in the Grand Underground.

** With the Game Corner gone, all of the TM moves that were sold there are now sold at the Veilstone Department Store (alongside Dazzling Gleam, Bulldoze, and Low Sweep), making it much easier to buy those moves than it was in Diamond/Pearl/Platinum, even if they're reverted to one-time use items. The held items Metronome, Silk Scarf, Wide Lens and Zoom Lens, which were also Game Corner prizes in the originals, can all be obtained for free throughout Veilstone City.

** Returning to the originals' infamously restrictive Regional Dex for both the player and the [=NPCs=] caught flak, but the Grand Underground provides most of Platinum's additions (plus a few non-Sinnoh mons) in a pseudo-Wild Area (also giving the player a much more diverse selection of Pokémon early in the game), and the postgame rematches feature NPC teams that incorporate Pokémon outside the Regional Dex, spiced up with surprisingly competitive sets.

** In the Grand Underground, you can find Smoochum/Jynx in both versions, as well as Teddiursa/Ursaring and Pinsir in ''Shining Pearl''.

* UnexpectedCharacter: In the Grand Underground, there's a handful of Pokémon that can be caught outside of the ''Diamond/Pearl'' Regional Dex before beating the game. However, there are some Pokémon families that weren't even in the Platinum Dex expansion to begin with that led to some surprise: Smoochum/Jynx in both versions, Teddiursa/Ursaring and Pinsir in ''Shining Pearl'', as well as Omanyte/Omastar, Kabuto/Kabutops, Lileep/Cradily, and Anorith/Armaldo due to their respective fossils becoming available in the Grand Underground just after you beat the mascot legendary.

* UnexpectedCharacter: In the Grand Underground, there's a handful of Pokémon that can be caught outside of the ''Diamond/Pearl'' Regional Dex before beating the game. However, there's three Pokémon families that weren't even in the Platinum Dex expansion to begin with that led to some surprise: Smoochum/Jynx, Teddiursa/Ursaring and Pinsir.
* SugarWiki/VisualEffectsOfAwesome: Some of the water effects are quite nice - such as the lakes having darker water or ripples appearing when you walk up to the water from a beach. Additionally, some of the trainers have nice animations such as Fishermen casting their Pokéballs like lures, swimmers rolling the Pokéballs off of their shoulders, or Fantina doing a pirouette. Volkner's gym is also quite beautiful looking with gears in the background that move.

** Candice, due to being the [[KryptoniteIsEverywhere Ice-type Gym Leader]], especially in ''Diamond and Pearl'' ( even if she has a [[BareFistedMonk Medicham]] for some reason, but it's extremely frail, so it'll only be a problem if whatever you're trying to beat her with only Fighting attacks). In ''Platinum'', she's a little bit harder however, due to her very fragile Snover being replaced by a bulkier mon (at least physically), Piloswine, who can hit you hard with Earthquake if you don't KO it in one hit. Her Abomasnow has her moveset reworked so she can hit steel types reliably with Focus Blast (she also gets Water Pulse to hit fire types, though a fire type still won't have any trouble KOing it) and her Medicham is removed in favor of her new ace Froslass : if Abomasnow came before her (which is probable), Froslass will be very hard to hit due to her ability Snow Cloak and it will only get worse after she stacks up Double Team.

** Candice, due to being the [[KryptoniteIsEverywhere Ice-type Gym Leader]]. She's slightly harder in ''Diamond and Pearl'', where she has a [[BareFistedMonk Medicham]] for some reason, but it's extremely frail, so it'll only be a problem if whatever you're trying to beat her with is weak to Fighting attacks.

** On the female side, Fantina's mannish face has made some people think that she's a crossdressing man like ''Emerald''’s Tucker.

* WhatMeasureIsANonBadass: Barry is often percieved as not as badass as Blue or Silver... despite having his highest leveled Pokémon being Level 85, and having ''temporarily dethroned [[MemeticBadass Red]] for the strongest trainer in the games'', something of which Blue and Silver never even came close to doing the last time they were seen in ''VideoGame/PokemonFireRedAndLeafGreen'' and ''VideoGame/PokemonGoldAndSilver'' respectively. Blue's highest leveled mon is 75 in the former, and Silver's highest leveled mon is 50 in the latter. Even taking into account ''VideoGame/PokemonHeartGoldAndSoulSilver'', Silver is still a good 20 levels lower than Barry by virtue of all of his mons capping at Level 60. Even to this very day, after 4 generations more worth of games and rivals, Barry's team is ''still'' the strongest leveled rival team in the entire core series games. This could be attributed to the reputation of FriendlyRival characters being perceived as "weaklings" and completely ignores the actual power of Barry's teams in comparison to [[InformedAttribute the allegedly badass Blue or Silver]] or that Barry does not make much contribution to the main plot, losing a fight against Team Galactic offscreen.
