* [[http://www.100bt.com/ Baitianinfo]] is a locally popular Chinese browser game developer with games having [[FollowTheLeader familiar gamplay]], but there are some questionable content. There is a cutscene in one of their games in which [[http://www.9u8u.com/uploads/allimg/120211/113341H57-2.jpg a character is thrown off from a building with small amounts of blood gushed from him]]. Although in Chinese, the same game has a cutscene with "WTF" in one of the NPC dialogue during a quest. And some story lines are [[DarkerAndEdgier gradually darker]] over time. The targeted age audience? 7-14.
* ''VideoGame/BrainDead13'':
** The protagonist gets to die in all sorts of graphically violent ways, which has made it extremely hard to understand why this was given a K-A rating [[note]](Kids to Adults, the mid-90's equivalent to the Everyone rating)[[/note]] then.
** There's the whole issue with Vivi the {{vampires|AreSexGods}}s and her ''[[{{Pun}} titillating]]'' appearance, [[BuxomIsBetter figures]] and MaleGaze, and one suggestive magazine in the FreezeFrameBonus that can be too suggestive for children, yet we may never understand why all of these are ''totally safe for kids'' with a K-A rating. What's even stranger is that Japan's game rating organization (pre-CERO) slapped each box of the game (exported from America) with an "all ages" (全年齢, ''zen nenrei'') rating on a green sticker, hoping that its audience of children would be less sensitive to mind-numbing bloodless violence and sexuality than America's children (due to cultural differences). The proof is in the pudding [[http://image.gamespotcdn.net/gamespot/images/bigboxshots/2/196812_14924_front.jpg here]].
** The [=iOS=] port averts this by ramping up the rating to a 12+, which is an equivalent of either a "Teen" or an "Everyone 10+" rating.
* ''VideoGame/DawnOfTheDragons'' is a Flash browser game that's marketed to children on kid-friendly sites like Kongregate with the promise of high fantasy and relatively simplistic gameplay. The premise is simple enough - a farmhand rises to become a champion. How that champion gets there, though, is brutal and unapologetic:
** Text and images show enemies being dispatched in a number of gruesome ways (having their throats slit, being impaled by multiple swords, being decapitated, main characters being covered in gore and viscera). Several of these deaths are described with paragraphs going into detail about the minutiae involved, and how the main characters stand back to watch someone they've just sliced open bleed to death.
** In "Peril of the Pumpkin Patch", two children are spied on and chased by creature with a flaming jack-o'-lantern for a head. His victim, the girl, has her head mounted on a pike (that is also seen in one of the chapter images), which is subsequently used to terrorize the residents of a local town.
* ''VideoGame/DevilChildren'', a LighterAndSofter ''Franchise/ShinMegamiTensei'' spinoff series. Most of the games never released outside Japan because they are so far from what is viewed as "appropriate for children" in the West, and even the ones that did had to be chopped up a fair bit -- though, surprisingly, Lucifer kept his name and his status as one of the good guys.
* There's a game called ''Dog's Life'' for PlayStation2. It's premise seems nothing bad. A cute game where you play as a dog trying to rescue his damsel-in-distress from a dog catcher, with some ToiletHumor and anatomically correct dogs (only in the CG, though) added in. By the end of the game [[spoiler:you learn the whole thing was a plan by the creepy cat food maker Ms. Peaches, who wants to make dogs into her cat food. You have to save Daisy from being killed by a long line of increasingly violent implements. And in the end Ms. Peaches holds both of you at gunpoint, spouts a bit of profanity, and eventually ends up falling into the now-defunct machine and getting caught in a comically large can as she curses you. And then her machine detects an error in the canning process, draws her back, and ''[[SurpriseCreepy brutally dismembers her]]'' to fit her into more standardized cans while speaking in edgy salesperson-like voice, even using her name as if it knows for a fact it's killing it's creator.]] This game was rated 3+ in Europe, but T in North America.
* The game "Learning with the PooYoo Part: 1" is supposed to be rated Early Childhood (in other words no violence) but has a moment where if you guess a question wrong an innocent animal falls from the cloud it's trying to jump to and dies.
* ''Franchise/TheLegendOfZelda'':
** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has a dungeon and a sub-dungeon that include zombies, mummies, hands sticking up out of acid, walls made of skulls, really long arms that grab you, frightening music, and a creepy miniboss. In addition, Castle Town while Link is an adult is a ghost town infested with zombies.
** ''VideoGame/TheLegendOfZeldaMajorasMask'' has recurring themes of death, apocalypse and corruption, as well as frequent instances of GettingCrapPastTheRadar. Yet it was rated ''E for Everyone''.
** ''VideoGame/TheLegendOfZeldaTheWindWaker'' definitely ''looks'' like it's for kids, and had an ''E for Everyone'' rating to match. Then you start playing and the first thing you see is an intro screen describing that Hyrule and it's inhabitants were destroyed [[TheGreatFlood biblical style]], then you get to see the [[NightmareFuel Re-Deads]], ''then'' there's the climax [[spoiler:where Link impales Ganondorf through the head and he turns to stone]]. Given these elements, saying this game is "kiddie" is a ''serious BerserkButton'' for its fanbase.
** The trope began to be averted with later ''Franchise/TheLegendOfZelda'' games, which got higher ESRB ratings so they would be aimed at older audiences. ''Twilight Princess'' was rated T, and nearly every game from ''Spirit Tracks'' onwards, including remakes of previously E-rated entries, were given [=E10+=].
* ''MagicalStarsign'' starts as a cute, fluffy game but once the second act starts things swiftly go downhill. There's too much horrible stuff going on here to list it all without taking up pages, but to sum it up: [[spoiler: The main plot is about bringing mages to a planet where just being there turns them into into gummy-like inanimate blobs to be used as fuel for a space worm]].
* ''VideoGame/MegaManZero'' looks like an average kid's game, but is the darkest series in the franchise, with the main plot being hinged upon ''genocide''. And somehow the ESRB saw fit to give this game an ''E rating''. From the [[IncrediblyLamePun bloody]] intro of Megaman Zero to [[spoiler: [[WellIntentionedExtremist Elpizo's]]]] [[SensoryAbuse ear-grating scream]], it's baffling on why it's rated E.
** And then there's [[PersonOfMassDestruction Omega]] and [[MadScientist Dr.]] [[UpToEleven Weil...]]
* ''VideoGame/{{MOTHER}}'':
** ''VideoGame/EarthBound'' is, for the most part, a fairly innocent, cartoonish romp through childhood wonder and quirkiness. Once in a while you encounter something a little off, like a distinctly cult-like religious group that partakes in human sacrifice. Once in a while you encounter something ''extremely'' off, like ''willingly allowing yourself to have your arms, eyes, ears, and legs slowly taken off''. Very few of these things have any build up, nor are they dwelled upon. They just sort of... happen, leaving the player wondering exactly how they should feel about it. [[spoiler:Then it's final boss time.]]
** ''VideoGame/{{MOTHER 3}}'': [[spoiler:Multiple incidents of FamilyUnfriendlyDeath, characters going through realistic emotional issues as a result, a scene where the characters (MushroomSamba) go on a terrifying hallucinogenic drug trip]], a villain who represents [[AllegoricalCharacter the sins of humanity]], animal abuse, child suicide, etc.
* ''VideoGame/NiNoKuni'' is in a similar boat to ''Wind Waker'' in that it uses colourful anime-style graphics (specifically, it was animated by StudioGhibli) despite it dealing with some surprisingly dark themes. The main character (who's only 13 by the way) watches his mother die of a heart attack only a few minutes into the game, and the eponymous 'other world' is very clearly a CrapsaccharineWorld with everyone living in fear of an EvilSorceror who can effortlessly MindRape anyone who even ''thinks'' about standing up to him. Then there's Myrtle's story in the real world, which gives a surprisingly realistic view of how domestic troubles can traumatize kids psychologically. [[ArsonMurderAndJaywalking And Drippy drops]] [[GoshDangItToHeck G-rated equivalents of]] ClusterFBomb all over the place.
* ''VideoGame/PaperMarioTheThousandYearDoor'' had some [[GettingCrapPastTheRadar very questionable dialogue]], two female main characters (a ghost and a wind-spirit/fairy/creature) who are completely naked (granted, [[BarbieDollAnatomy neither has nipples or vaginas]], but still), Princess Peach as an InvisibleStreaker, demonic possession, and Hooktail chewing up Toads while they are still alive. The rating? E.
* The ''Franchise/{{Pokemon}}'' games are considered all-ages rather than strictly for kids, but still have a situation similar to some of the games here:
** The plots of the games can run rather dark and complicated for games meant to be appropriate for kids, and some hidden mechanics- [[http://bulbapedia.bulbagarden.net/wiki/Effort_values effort values]] [[note]]Starting ''Pokémon X and Y'', effort values are now seen in a Pokémon in Super Training.[[/note]]and [[http://bulbapedia.bulbagarden.net/wiki/Individual_values individual values]], for starters- are rather complex and draw a large PeripheryDemographic to the Pokémon competitive scene. Of course, this is rather mitigated by the fact that the player can easily [[PlayTheGameSkipTheStory ignore the story and hidden mechanics in favor of making the monsters battle each other]] for the most part.
** The Sea Mauville scenario in Omega Ruby and Alpha Sapphire, which also develops Professor Cozmo and Gym Leader Wattson, adds a large helping of material normally not used in kid's shows. It includes a SenpaiKouhai schoolgirl couple locking themselves into a side room for a private moment, finding abandoned documents narrating the rise and fall of the Mauville MegaCorp, an account of an employee's failing marriage from the perspective of a child, books about dealing with unemployment, debtors losing their Lopunnite Mega Stones to their debt collectors as collateral, and perhaps darkest of all, [[spoiler:''the harvesting of the life-energy of Pokémon as fuel'']], which is also implied to have [[spoiler:led Wattson to forcibly tank ''all of New Mauville'']]. Among such grown-up themes, it's clear that the writers were expanding on the maturation of Pokemon narrative content as seen in X & Y.
** In ''VideoGame/PokemonMysteryDungeonRescueTeam'', you have to save the world from an impending comet while fighting against a Gengar that accuses you of being a cruel traitor that was cursed for selling out his own Pokemon. In ''VideoGame/PokemonMysteryDungeonExplorers of Time and Darkness'', the plot is that you have to change the future because, as it is, [[spoiler: it is a world of ''complete'' and ''utter darkness'', where the sun never rises and the wind never blows.]] Besides that, innocent Pokemon get kidnapped, you have extremely freaky visions and, above all else, this whole game is a [[spoiler: ''suicide'' mission. That's right. You ''die'' at the end and you ''know'' you're going to die.]] Chew on that. Finally, in the rerelease of ''Time and Darkness'', they have mini-stories. And each one of those has a bad part, but the worst is probably in the last one, when one of the antagonists plans to [[spoiler: ''suck your soul out of your body (think [[Franchise/HarryPotter dementors]]), possess you, and go to the past in your body to convince people he is you.'']] In the post-credits story, [[spoiler: the BigBad disguises himself as a good guy, visits you in your dreams, and tells you that the world is going to end, that it's all your fault, and that ''you and your partner should kill yourselves.'']]
** ''VideoGame/PokemonMysteryDungeonGatesToInfinity'' appears to be LighterAndSofter... until [[spoiler: you get betrayed by a fake damsel in distress, learn that the BigBad is an omnicidal nihilist who has murdered potentially ''dozens'' of other humans summoned to stop him, see one of your allies ''frozen into a block of ice and shattered into pieces'' and fight a non-Pokemon EldritchAbomination composed of hopelessness, mistrust and despair]]. [[SarcasmMode Definitely kid-friendly.]]
* ''VideoGame/RType Delta'' is rated E. The final stage [[spoiler:features depictions of fetuses as enemies to shoot.]] The ending for the R-13 [[spoiler:features it becoming captured by the Bydo, with the final shot after the credits being of the ship enveloped by Bydo matter.]]
* ''Franchise/RatchetAndClank'':
** The first four games are rated T.[[note]]Although it would later be rerated E10+ when it was remade in HD[[/note]] After the E10+ rating was invented, subsequent games were labeled as such despite increasing rates of violence and innuendo. Even Insomniac states that the games aren't meant for kids. They say their audience is 18-34 year olds.
** "A Crack in Time" was originally supposed to be called "Clockblockers".
** "All 4 One" was supposed to be called "4-Play".
* ''VideoGame/Rayman3HoodlumHavoc'' has all sorts of sexual innuendos, Globox getting drunk, and the swamp hag using the word "pervert".
* VideoGame/RaymanOrigins is also well known for making the fairy girls (all of them) [[MsFanservice absolutely blatant sex-objects]], complete with HartmanHips, JigglePhysics, Suave voices (albeit in pig-latin), porno-like music when you save them and the trailer shows Rayman using his hair to blow Betilla's skirt up...also, Betilla created him, so that technically makes him [[ParentalIncest his MOM]]. Just to top it off, the manual describes Betilla as a [[GettingCrapPastTheRadar badASS]].
* Some attribute the commercial failure of ''{{Shantae}}'' to this, among other factors. ''Shantae'''s cutesy, colorful graphics, goofy humor, being on the kid-friendly GameBoyColor, and a definitely present twinge of GirlsNeedRoleModels certainly suggest it's a kid's game. The problem is, it's also strangely... [[ParentService sexy]] for something aimed at kids, and also more difficult than your average kid's game.
* The ''Franchise/SlyCooper'' series has you play as a raccoon thief who [[HarmfulToMinors witnessed his parents' murder at age eight]] and seeks to [[YouKilledMyFather avenge their death]] in the first game. In addition, the series contains [[GettingCrapPastTheRadar suggestive humor]], depictions of tobacco use, and references to alcohol. ''[[VideoGame/Sly2BandOfThieves Band of Thieves]]'' even features ''drug dealers'', and it was rated ''E''. To this day, no game in the series has ever received a rating higher than E10+.
* ''Franchise/SonicTheHedgehog'':
** There was a minor InternetBackdraft over the fact that one of the guys working on the games in the run-up to ''VideoGame/SonicTheHedgehog4'' stated that their main demographic was children. This was because the fandom was already accustomed to the darker plots of ''VideoGame/SonicAdventure2'' and ''VideoGame/ShadowTheHedgehog'', and having the game creators acknowledge Sonic as mainly a children's franchise was shocking to some of the online fanbase (which tend to skew older). After the release, it's kind of died down.
** ''VideoGame/ShadowTheHedgehog'' was purposefully intended for older fans. It was originally going to have a T rating, but backlash for giving Shadow his own game and intentionally making a DarkerAndEdgier installment (despite fans requesting that Shadow get his own game since ''VideoGame/SonicAdventure2''/''VideoGame/SonicHeroes'' and requesting for a DarkerAndEdgier installment for a while) led to SEGA/Sonic Team censoring it to fit for the E10 rating. This shift led to the final product being torn between which group of fans it was trying to appeal to, succeeding at neither.
** The inclusion of E102 Gamma in VideoGame/SonicAdventure, Tails' and Eggmans' mech sections in ''VideoGame/SonicAdventure2'', and Shadow's weapon of choice in ''VideoGame/ShadowTheHedgehog'' were intended to appeal to a segment of Sonic fans who had apparently been demanding gunplay in Sonic titles. While Gamma and the ''Sonic Adventure 2'' mech sections were average at best, the inclusion of guns in Shadow's game lead to the single biggest complaint people have about the title. Make of that what you will.
* ''Franchise/{{Metroid}}'':
** ''VideoGame/SuperMetroid'' had Crocomire's [[FamilyUnfriendlyDeath horrific death]], and it got a K-A rating. Then when it came to Virtual Console in 2007, it still kept its Everyone rating.
** ''VideoGame/MetroidFusion''. You begin with the story being that Samus was ''nearly killed'' by a parasite called the X, and you're dropped right into the BSL Research Station, which is, as far as you know, completely devoid of human life thanks to the X. Early on you have to navigate a series of eerie unlit corridors because there's been an ''explosion'' in the quarantine room. Turns out it's just a Hornoad-X, but if you explore a bit you find a room completely frozen. If you decide to continue further inside, despite the damage you take from the cold (you've been injected with Metroid DNA) you see [[spoiler: '''Ridley''' (Who was supposed to be '''dead''') frozen in a block of ice.]] Play farther into the game, go down the Main Elevator, and what appears to be [[spoiler: Samus]] bursts into the shaft. [[spoiler: Then it zooms ''right'' in on 'her' face, revealing that it's some kind of mimic.]] You later find out that this mysterious entity is called the [[spoiler: SA-X, and that ''it's tracking you.'' You also can't even hope to kill it yet. You are told to ''run'' if you encounter it.]] And it '''does''' catch up with you. Then there's a boss called the [[spoiler: Nightmare]]. It's been flying through the background of the damaged area of the ARC Sector, startling you the first few times it happens. Then you [[spoiler: fight it]]. It has [[spoiler: a creepy mask, and when you damage it enough the mask breaks, revealing its disgusting alien face that, as you damage it further, begins ''dripping'']].
* Both the original ''VideoGame/{{Vietcong}}'' and ''Fist Alpha'' are rated T. Yet, they're full of [[ClusterFBomb Cluster F-Bombs]], not to mention having weapons that can dismember enemies. Averted with ''Purple Haze'' and the second game, which are rated M.
* The two ''VideoGame/TalesOfXillia'' games are this trope in Australia, where they somehow managed to get PG ratings despite the first game having violent deaths and occasional blood in cutscenes and pretty explicit sexual references (there's jokes about bondage kinks) and the second game being BloodierAndGorier, featuring huge amounts of blood in death cutscenes, terrorist attacks complete with masses of bloody civillian bodies (in one of the first areas of the game, at that), sexual references as normal and ''incredibly'' dark themes towards the end of the game. (The main character has to [[spoiler: murder his brother to save the world]])
