* In general, many people are still under the impression that video-games are for kids, and kids only. This can lead to people arguing that they shouldn't have any violence or sexualization at all since surely those titles can't be for older players, while others will blindly buy any title for their children, assuming it'll be fine.
** An extreme case of this could be traced back all the way to the Commodore 64 era. Back then it was so easy to program a game that even a child could do it. It's already true that most kids already sold their patent rights for the games they make at around £10 to corporations, but corporations went far enough to bind kids to contracts in which kids will work for the company 7 days a week, with lots of games to make in a single day in which they earned very little money. Yet some parents actually allowed their kid to sign such a contract.
* Pretty much any game in which the graphical art style is anything other than realistic will get mistaken for being for kids by some people. The most common being games with cartoon or anime style designs and overall looks. This is also a common thing with parents. Parents tend to assume that just because a game has colorful anime or cartoon graphics, that it was made for kids and is suitable for their children to play. This leads to children often playing games they ''really'' shouldn't be playing.
* The unquestionable king of this trope would have to be ''Franchise/MortalKombat'' and its sequel games. Literally since the game first came out on arcade systems, the game was horribly mistaken to be a child-appropriate videogame. The series may be an adventure series about magical ninjas, have beautiful artwork, awesome character designs, visually-appealing graphics, and a well-built fighting control system, but it is also made brutally clear that this game was ''not'' devised for younger players. The series is well-know for its [[FamilyUnfriendlyDeath full-blown blood and gore]], deeply complex character arcs, AxCrazy antagonists who're [[HeroKiller not afraid to personally murder characters onscreen]], [[{{Fanservice}} heavily sexualized characters]], and the game actually ''encourages'' you to [[KickThemWhileTheyAreDown finish]] your opponents off. Yet, to this very day you'll still find a child who has played one of the titles.
* Although the ''Transformers'' have always been the subject of the [[WhatDoYouMeanItsForKids other trope]], the game ''Videogame/TransformersWarForCybertron'' is definitely ''not family friendly''. The game clearly establish that WarIsHell, is packed with references for older fans of the franchise, contains a lot of robot blood, and is full of brutal death. To drive the point across players, [[BigBad Megatron]] is an obvious {{Expy}} of ''Adolf Hitler''.
* ''VideoGame/TransformersFallOfCybertron'' may hail from a franchise driven by toys but don't let that fool you into thinking that this game is kid-friendly. This is easily the darkest the Transformers has ever gotten, with loads of FamilyUnfriendlyDeath, ''robot blood'', overall depressing story, and Anti-war message, which isn't surprising as this game is connected to [[WesternAnimation/TransformersPrime TF:Prime]], itself a very dark series. Have we also mentioned that this might be one of the ''very few'' times the ''Decepticons'' were portrayed in a morally grey manner?
* ''VideoGame/{{Portal}}''. The concept of a puzzle game with quirky humor, cake, and a metal box with a pink heart on it may sound kid friendly at first, up until the part where you learn that the psychotic AI nerve-gassed every living creature in the facility, [[spoiler:''on Take Your Daughter To Work'' day]].
** And look, ''VideoGame/{{Portal 2}}'' has [[Main/SchmuckBait cute little robots that give each other high fives]]! [[VideoGameCrueltyPotential Let's see how many ways they can violently kill each other!]]
** Yet many scientists still say that it's a good thing if your kid plays this game. This has probably to do with the huge amount of three-dimensional thinking that is required to beat a few levels.
* ''VideoGame/AmericanMcGeesAlice''. As if the cover art and big M-letter on the box weren't sign enough that this game (with violence comparable to what you'd find in ''VideoGame/{{Doom}}'' and ''VideoGame/{{Quake}}'') was far removed from the Disney film...
** Doubled by ''VideoGame/AliceMadnessReturns''. In short, the BigBad is a [[PsychoticManchild crazed]] pimp trying to make Alice a child prostitute.
* ''OgreBattle'' and ''Tactics Ogre''. Don't let the cartoonish sprites fool you: these games deal with war, betrayal, murder, politics, and everything that makes the real world a mess.
* Do not let your kids play ''VideoGame/{{Eversion}}'' at all despite [[CrapsaccharineWorld its family-friendly looks]]. Why, even [[http://zarat.us/tra/eversion/ its website]] warns you not to let them play!
* ''VideoGame/TheBindingOfIsaac''. Oh sure, it looks very cutesy and colorful... [[spoiler: until you realize that Isaac's mom is a murderous psychopath! ]]. Additionally, it is pretty gory, and also takes a rather... shall we say, artistic license with the Biblical account of the actual binding of Isaac, which some may find offensive. It was reportedly rated 16 in Germany for this reason.
* ''VideoGame/MonsterParty'' for the NES was released back when there were no ratings for games, and it has gory visuals throughout. And this is ''after'' it was seriously toned down.
* [[http://videogames.yahoo.com/feature/watchdog-group-nintendo-no-longer-quot-family-friendly-quot-/1295531 The National Institute on Media and the Family]] has taken Nintendo to task for releasing ''VideoGame/MadWorld'' on their "family friendly" UsefulNotes/{{Wii}} (never mind the fact that it was actually {{Sega}} that published the game). Apparently they didn't notice ''VideoGame/RedSteel'', ''VideoGame/NoMoreHeroes,'' ''VideoGame/HouseOfTheDead'', ''VideoGame/TheGodfather'', ''VideoGame/DeadRising'', ''VideoGame/DeadlyCreatures'', ''Franchise/ResidentEvil'', and ''VideoGame/{{Manhunt}}'' (not that those were released by Nintendo either, but they're still on the Wii) and thus, they became one more laughing-stock on the Internet. Nintendo countered to [[FunWithAcronyms NIMF's]] claim about the Wii being "for the entire family" by saying that the Wii is indeed for everyone...and when saying "everyone", they throw in hardcore gamers in the equation. Apparently, [[FanDumb no one associates "hardcore gamer" with "family" today]].
* There are plenty of pornographic arcade games that look like kids' games due to their simple gameplay and cute, colorful graphics... until you beat the level and start seeing pictures of naked women.
* A few pornographic Atari games. Somehow, in the late stage of the 2600's lifespan, the winning strategy for a game was to feature 8-bit porn.
* ''Stupid Invaders'' looks cute, thanks to the characters, but quickly reveals its unsubtle humour.
* This [[http://kotaku.com/5753506/kids-shouldnt-play-games-about-jerking-off story]] about Kotaku columnist Luke Plunkett discovering Stroker for the Commodore 64 as a young child only re-enforces this trope.
* ''Franchise/ShinMegamiTensei'': a RPG with pixies and Jack Frosts... where the USA fall under the control of a fanatic Christian cult ruled by supernatural beings which uses the US nuclear arsenal to rebuild civilization around a fascist theocracy, and God '''[[GodIsEvil really approves]]''' of what they are doing--and he's ''still'' [[BlackAndGrayMorality the closest thing to a good guy in the story]]. There's a reason this is a game where the OmnicidalNeutral path is generally agreed on as the ''most moral''.)
** Any game from ''Shin Megami Tensei''[=/=]Creator/{{Atlus}}. For something that kids can buy, ''VideoGame/DevilSurvivor'' has to be one of the most fucked up games ever (and it's only rated T!). Proving once again that parents should read the back of the box before letting kids buy video games.
* ''Shin Megami Tensei''[='=]s spinoff series, ''VideoGame/{{Persona}}'', gets it just as bad:
** The original ''VideoGame/{{Persona}}'' was rated E. ''The original Persona was rated E.'' We're talking about a series with Mara, an [[EldritchAbomination Eldritch]] GagPenis. What in YHVH's name was the ESRB thinking!?
** ''Persona 3''. The main characters regularly shoot themselves in the head with handguns. And one of them is a fourth grader. But the visuals in the beta version made the handguns look much more realistic. These were changed as Adults Only is not permitted on console games.
** ''Persona 4'' is a colorful spectacle about a transfer student that moves in with his uncle, a respectable policeman and makes lots of friends! Not to mention the first proper dungeon is set in a fairytale castle, so it must be kid-friendly right? Wrong. There's more sexual themes you can shake a stick at (of which the strip club dungeon is the icing on the cake), [[spoiler: your adorable 7 year old cousin is kidnapped and dies in the hospital (though she may return under conditions), and a policeman tries to rape two women.]]
** ''Persona Q'' added onto it, with the [[spoiler: entire plot centered around the death of a teenage girl and purgatory]], along with the [[spoiler: imminent ''erasure'' of all the characters you love from Persona 3 and 4 implied if you fail.]] All encompassed in a cutesy art style to rival even the best anime!
** It should be noted that the latter three are rated "M".
*** A recurring enemy is Mara, which looks like a giant penis with tentacles.
* ''VideoGame/{{Xenogears}}'': Humongous Mechas are for kids? What about the protagonist [[spoiler: being an omnicidal maniac who can and does commit genocides by himself]], when one of the dominant religion is a front for a decadent dictatorship where being racist is considered to be a civic duty?
** Not to mention [[spoiler:God, Deus (well, not ''quite'' God, the Demiurge) is completely evil and to resurrect himself, ''90% of the entire human race'' mutate into Wels, mini-{{Eldritch Abomination}}s that ''become spare parts'' for him.]] And then there's the religious undertones, sporadic sexual content, and the overall general dark tone of the story. To put it in perspective, it is probably Square's darkest game ''to date'', bar none.
** ''Xenogears''? What about ''VideoGame/{{Xenosaga}}''? Cannibalism, heavy amounts of blood, the religious references, genocide, just about any scene with [[AxCrazy Albedo]], mind rape, light nudity, exploring the past of a serial killer who basically had to have his mind overwritten to the point of insanity, incestial undertones, suicide, and of course [[spoiler: the Bittersweet Ending done because the game had to end on the third game when it was planned to be 5 or 6 games long, resulting in the deaths of a LOT of characters]].
* The ''VideoGame/ArcTheLad'' series. The hero of the first episode is a terrorist whose uncle committed genocide against the people of the hero of the second episode before turning said hero into the prototype of bioweapons made by turning children into bloodthirsty monsters. And that is just the beginning, for it gets worse after that. But it has cute graphics.
* ''VideoGame/ConkersBadFurDay'' has {{talking animal}}s and has a cartoonish appearance, but is rather bloody and riddled with profanity[[note]]a few words are bleeped out, although words like "shit" and "twat" remain[[/note]], and advancing through parts of the game involve getting drunk, and that's just the start. It does have numerous warnings that it's not meant for anyone under 17, as well as a giant ESRB M-rating on the box; still didn't prevent children from playing it.
** This was compounded by the fact that Conker ''did'' star in the kid-friendly game ''Conker's Pocket Tales'' while ''Bad Fur Day'' was stuck in DevelopmentHell. During this time, he also made cameos in ''VideoGame/DiddyKongRacing'' and 'VideoGame/BanjoKazooie'', both of which are also kid-friendly games.
* The initial retail release of ''VideoGame/CuteKnight'' was rated E due to someone going "It's anime, it's for girls, it's got to be fine." The game was then withdrawn from stores because it contains references to religion, violence, blood, prostitution, incest...
* ''LittleKingsStory'' is rated T due to alcohol references, polygamy, religion and, sometimes genocide. Yet it's all presented in a delightful storybook style with vibrant colors and cutesy graphics. Well, the Wii game, anyway. The Vita sequel uses a generic anime artstyle because everyone mistook the Wii game for a children's game.
* The ''VideoGame/FireEmblem'' series may be high fantasy with bright, colorful graphics, but it's also filled with war, murder, racism, genocide, and incest, ''especially'' the Jugdral series. The only reason that these games have never been rated higher than T is that it's never shown, just spoken about and implied. There's a reason the first few games didn't [[NoExportForYou make it out of Japan]]. Even ''Blazing Sword'', the very first ''Fire Emblem'' game released internationally and which was rated E in its original release, has direct references to mass murder and human trafficking before you've even left the tutorial chapters.
* The (To be fair, newly formed) ESRB must have been HIGH when they rated VideoGame/LunarEternalBlue, a game with blood, partial nudity, swearing, sexual innuendo. and heaping helpings of NightmareFuel, a "K-A" rating. Thankfully the [[VideoGame/LunarEternalBlue the remake]] for UsefulNotes/PlayStation gave it a more fitting T rating.
* ''VideoGame/HeartOfDarkness''. Rated E for Everyone, despite the painful looking -- though [[BloodlessCarnage not actually gory]] -- death animations, not to mention the abhorrent scenery. Remember kids, shadows are very dangerous things.
* ''VideoGame/CastlevaniaBloodlines'' for the Genesis received a "GA" (General Audiences) rating, despite its large amounts of gore.
* ''VideoGame/GrandTheftAuto''. It is amazing and disgusting how many parents think it's fine for their kids to play GTA. A personal favorite parental defense: "Grand Theft Auto is the only M-rated game we let him play."
** Conversely, most of the controversy surrounding the game stems from this trope being applied to video games as a whole. MoralGuardians think that only kids should play video games and therefore making one about violent crime is absolutely heinous.
* ''VideoGame/BatmanArkhamSeries'':
** ''VideoGame/BatmanArkhamAsylum'' may be a superhero game, but it was only the lack of gore and stronger language that kept it from getting an M rating. The game is so dark, that many are still shocked that it didn't get an M rating.
** ''VideoGame/BatmanArkhamCity'' is even worse - granted, there is only one scene containing blood, but the game features Victor Zsasz telling of why he carves his own skin to keep count of murders, the Penguin audibly freezing a cop's hand and shattering it with a hammer and [[spoiler:Hush]] slicing people's faces off ''before killing them'' so he can [[spoiler:look like Bruce Wayne]] to name a few.
** The prequel ''VideoGame/BatmanArkhamOrigins'', likewise, is chock full of not-kid-friendly content. Near the beginning of the game, [[spoiler: Joker, disguised as Black Mask, murders the police Commissioner via gas chamber during a prison riot]], and it only gets worse from there. Highlights include [[spoiler: Mad Hatter kidnapping a young girl, who, even after being rescued by Batman, is clearly emotionally damaged for life, Shiva murdering/attempting to murder police officers to draw Batman's attention, the bank manager laughing to death with a [[NightmareFace permanent smile plastered on her face]] from Joker's toxin, Bane almost murdering Alfred, and an ''[[ThroughTheEyesOfMadness entire sequence]]'' played from The Joker's point of view, complete with a picture of [[HumanoidAbomination how he sees Batman]].]]
*** It doesn't help that you play the game as a ''much'' less refined and experienced Batman than usual, who is ''much'' more brutal than his ten-year-older-version you play in the other games. Bats has several {{Jerkass}} moments throughout the game and he has a few moments that even approach SociopathicHero levels. Luckily, he goes through some CharacterDevelopment as the story goes on.
** The fourth game, ''VideoGame/BatmanArkhamKnight'', actually got an M rating from the ESRB. Why, you ask? There's [[spoiler: two suicides]], [[spoiler: several torture scenes]], and the player can [[spoiler: actually shoot hostages and certain members of Batman's rogues gallery in a hallucination near the end of the game.]] And that's just the main game, without the Season of Infamy DLC which is notably BloodierAndGorier. No doubt, however, uninformed parents will still buy it for young, easily-scared children, because it stars Batman and comics can't be ''that'' bad, right?
*** Then there's the playable Red Hood, who's primary gadget is always an instant kill, and who breaks his enemies necks to silently take them out. While the player could kill his enemies as Joker in Arkham Asylum, his kills were limited to one handgun shot and takedowns still had some humor value.
* ''VideoGame/CallOfDuty'' is still subject to this, even though all the games after the third have been rated M. The ones made by Treyarch turn this UpToEleven with more gore, cursing, and horrific imagery. And yet, it's extremely common to find 4-12 year-old children playing online.
* In the same vein as ''Call of Duty'' is ''Franchise/{{Halo}}'', which has a bit of that ''StarWars''-ish look to it, what with big heroic guys in green space armor gracing the cover. Needless to say, any bit of knowledge of the game makes it clear that it is most definitely ''not'' for children. Of course, being a massive big-name game, children are sure to hear of it and make their parents well aware of that fact, hence you will always - ALWAYS - find at least one 5-year-old playing on Xbox Live with you.
* ''VideoGame/TeamFortress2''. At first glance, it looks like an innocent game due to its Pixar-esque artstyle...but then comes the massive amounts of blood and gore. And the jars of urine. And Spy's relationship with Scout's mother according to the official short "Meet the Spy", not to mention the pictures that Spy shows and [[spoiler:his head graphically exploding]]. However, just like with any FPS, you will find many 10-year-old kids playing the game online. [[note]] Although there aren't as many kids playing it as there are Call of Duty and Halo. Some of them have said it looks 'kiddy'[[YouMakeMeSic (sic)]].[[/note]]
** And then comes the "Meet the Pyro" short, in which we find out that as Pyro kills his opponents, [[spoiler:he sees it as him playing around with cherubs in a [[TastesLikeDiabetes magical, colorful world]].]]
* The English download site for the pigeon-dating game ''VisualNovel/HatofulBoyfriend'' gives it a G-rating, and it is officially rated E10+ by the ESRB. Keep in mind that this game has an ending where [[spoiler:you get ''decapitated'' by a psychotic doctor who regularly kills his bird patients and turns them into quill pens and turkey dinners]] and a lengthy BBL route that ''starts'' with [[spoiler:the bird characters finding the human protagonist's ''chopped-up remains'' all over the school]] and gets progressively more fucked up from there on.
** Even the free version has the aforementioned [[spoiler: decapitation by DeadlyDoctor ending, who also mentions that he'd like to [[{{Squick}} get intimate with your innards]] when he's done]], which should tell you how kid-friendly this game ''ain't''.
--->'''[[LetsPlay Angie Gallant]]:''' A fat bird should not be [[spoiler: fucking my intestines]]!
* ''VideoGame/MetalGearGhostBabel'' is rated E for Everyone, the only game in the entire ''Franchise/MetalGear'' series released during the existence of the ESRB which got less than a T rating (and all [[VideoGame/MetalGearSolidPortableOps but]] [[VideoGame/MetalGearSolidPeaceWalker two]] got an M). The game includes: ethnic cleansing, a serial killer who makes life-size dolls out of his victims, said serial killer discovering the dismembered corpse of his sister, and a boss who commits suicide by burning himself to death while crying out in orgasmic joy. [[ArsonMurderAndJaywalking On the plus side, Snake doesn't smoke in this one!]]
* The ''VideoGame/{{Fable}}'' series has cartoony graphics and a generic fantasy setting. It is ''far'' from a children's game, especially Fable II.
* ''VideoGame/{{Glitch}}'' is a browser-based game with cute graphics, talking animals and trees (including an eggplant which, naturally, grows eggs) - which also features alcohol, drug use (in the form of no-no powder which temporarily gives you unlimited energy - then you die unless you take another dose), some sex-related jokes, and a somewhat disturbing level in hell. According to the terms of service, the game is not intended for children under 14, and children under 18 need parental agreement.
* ''VideoGame/SamAndMaxFreelancePolice'' (the Telltale series). It looks like a kid-friendly game on the outside because of the cute animal characters, but the humor is definitely not for kids. Sure, it may not be as bad as other examples on this page, but ''still''.
* ''VideoGame/SealOnline'' is a massively multiplayer role-playing online game with cartoony graphics, cutesy characters, and fun music that kids would think is suitable, until when they see the [[KillerRabbit Rascal Rabbit]]. It is rated T for Teen according to ESRB in the United States (12+ and 18+ uncut in South Korea, depending on which version) due to violence, alcohol references, suggestive characters, and such, despite being intended for younger players according to YNK Interactive's defunct website.
* The [[ShoddyKnockoffProduct pirate original]] Famicom game ''Disney/TheLionKing 5'' seems like a perfectly kid friendly game at first, that is until you get a GameOver and find [[spoiler: the character committing suicide. Yes, really.]] [[DudeNotFunny It seems like it was done as some sick joke by the programmer]].
* The ''WorldOfWarcraft'' expansion pack Mists of Pandaria received this response in spades from a lot of fans, just because the Pandaren and the titular continent of Pandaria look too 'childish' or 'goofy' for, what was considered 'normal' WoW storylines like the Lich King and Deathwing. "We were fighting demons, undead, and giants dragons, and now... pandas." Was a common response to the expansion. In reality, however, it is one of the darker expansions of the franchise (Maybe out darked by Wrath of the Lich King). After all, sure the Pandaren are pretty cute. But they also get drunk often, enjoy getting in bar fights, and have an entire martial art centered around fighting while drunk and setting your enemy on fire after you've doused them in flammable brew. But awww, he's got spots around his eyes!
** Also the entire expansion has a B plot of "War is hell for those dragged in" as it displays what the fighting between the Alliance and the Horde is doing to the other races on Azeroth by dragging the fight to Pandaria, whose people don't care about either side. This also hands the horde [=NPC=]s the villain ball as unlike the Alliance, the Horde continues to make things worse in the name of conquest. The end result is the final boss of the expansion being Garrosh Hellscream, the Orc and overall Horde leader. This ends with both factions (The horde being represented by "rebels" consiing all non Orc forces (plus payer orcs) laying siege to the Orcish capital. Because a bloody siege is totally for kids...
* ''EdnaAndHarveyTheBreakout'' got a "No age limit"-rating in Germany on its first release. Never mind it deals with several murders (one committed and one facilitated by the main character), death penalty and psychology above the head of most children. The maker was so annoyed that he said "Fuck!" a lot during the commentaries for the extended version. He got the "12+"-label he had wanted.
* The first two ''VideoGame/DukeNukem'' games are [[EarlyInstallmentWeirdness relatively family friendly side scrollers, where Duke mainly shoots robots]]. ''VideoGame/DukeNukem3D'' and its follow-ups on the other hand...
* ''Franchise/KingdomHearts'' is a crossover with Square Enix and Disney characters in one franchise. Does the presence of Disney characters indicate that it is kid friendly? Not really. Regardless of age ratings, TetsuyaNomura once said in an interview that ''KingdomHearts'' is actually not aimed at children. Justifying this not just includes a complex story but also brutal killing scenes, extremist-like villain motives, themes of depression, and more.
** Doesn't help that there's no blood and gore, so people don't think it's that violent. Yes, [[BloodlessCarnage removing some red stuff]] when someone gets stabbed in the chest or has their eye [[EyeScream shot off]] automatically makes those scenes less violent and more kid-friendly, [[SarcasmMode right?]]
*** The hero stabs himself and he even does it with a grin, and that's just the first game. Wow, that sure sounds kid-friendly!
* ''VisualNovel/VirtuesLastReward'' falls into the category of being a game that would likely be passed off by parents as being a cartoon and for their kids. Just a few moments of playing said game and seeing the heavy cussing, violent situations and heavy use of sex jokes, should show anyone that that it's not for kids. Heck, just looking at the rating the game got, M for Mature [16+ in the UK], would tell parents its not for kids.
** And before that, there's ''VisualNovel/NineHoursNinePersonsNineDoors''. Oh look at the fun, anime characters making pipe jokes and giving out four-leafed clovers for good luck, isn't it cute? Yeah, if you consider strangers being forced into playing a sadistic game where they can be blown up by a bomb that's been placed in their gut, on a sinking ship cute. Not to mention that [[spoiler:there are two men who actually DO get blown up...in VERY descriptive and grisly detail. And to add salt into the already deepening wound, most of the bad endings in the game end with a huge massacre of the main cast, and the game has swearing. LOTS of swearing]]. One has to wonder how a parent could even make this mistake when A SINGLE SECOND of research on the game, or even looking at the back of the game box, would indicate to them that the basic concept of the game is about a sadistic psychopath's game.
* ''VideoGame/TheWonderful101'': a humorous game about brightly costumed superheroes saving the world from invading aliens that use robots to fight their war. What'ya mean it's really hard, the characters are often lewd and it deals with adult themes? At least in regards to the potty mouths of the characters; these were added to the game to AvoidTheDreadedGRating but it may have backfired resulting in a game that appealed to only a niche audience.
* ''VideoGame/AngryVideoGameNerdAdventures'' looks like another retro game. Of course, anyone who knew about what the game is based on should know it's anything but, especially the level based on the Atari Porn games. The Nerd himself lampshades on that level during the review of the game.
--> "Next is a level based entirely on the Atari Porn games. Who would do that? Don't look, kids."
* ''VideoGame/{{Psychonauts}}''. Nickelodeon-eque art style? Check. Ten-year-old protagonist? Check. Takes place in a summer camp? Tons of cartoony, well-written humor? Check. Relatively clean dialogue, barring a few AvoidTheDreadedGRating moments? Check. Creator/RichardStevenHorvitz? Check and check. Sounds like a great game for your kid, right? Sure, if you're fine exposing them to excessively mature topics like FamilyUnfriendlyDeath, suicide, child abuse, and psychological illnesses like paranoid schizophrenia and depression, not to mention a lot of BlackComedy with numerous references to sex, drugs, and alcohol, and a final level that will forever haunt their nightmares.
* One of the early 3D M-Rated games called ''VideoGame/ShadowMan''. This game would go as far as to slap into your face with [[http://img3.wikia.nocookie.net/__cb20091023051929/vsrecommendedgames/images/9/98/Shadow-man-n64.jpg its cover art]] that it is not intended for kids, for good reasons. It is a gory action-adventure game that was filled to the brim with references to life, death and murder and the game itself used Voodoo Mythology for its setting, which meant it was filled with very intense NightmareFuel. The problem is that it was action-adventure, so people thought it would just be as dark as ''VideoGame/TheLegendOfZeldaMajorasMask'', which is dark enough for a kids game.
* ''VideoGame/BrothersATaleOfTwoSons'' is a game full of magical whimsy as we follow two [[KidHero kid heroes]] wandering around a fantasy world on an adventure to save their father. It's also filled with literal rivers of a blood, corpses decorating the dark atmosphere, mythological creatures coming out of the shadows to murder you, and the heavy possibility of the two young boys dying violently if the player fails. In fact, [[spoiler: one of the young brothers ''dies onscreen'' through a CruelAndUnusualDeath and the other brother must bury his fallen family member in an emotional scene.]] Nevertheless, the "T" rating is ignored by quite a few people purchasing the game and was even nominated numerous awards for being the best ''family'' title.
* ''VideoGame/ShadowTheHedgehog'' is an interesting case of this. It ''was'' aiming for an teen audience based on the popularity of [[DarkerAndEdgier Darker and Edgier]] FPS's like CallOfDuty, but they figured that Sonic game made for adults wouldn't sell, so they toned it down for kids. It was still very dark, however, leading it to fall under [[WhatDoYouMeanItsForKids the opposite trope]] instead.
* ''VideoGame/{{Vexx}}'' is one of those games that was released during the height in popularity of 3D-platformers, so everyone who saw it assumed it was for kids. It features gore, genocide and slavery. Suddenly it becomes painfully obvious why the game got a T-rating.
* There's a disturbing amount of small children who have played ''VideoGame/FiveNightsAtFreddys'' and its sequels. Granted, the games aren't as bad in terms of gore, as most of the worst stuff is either hidden in shadow, shown in 8-bit format, or simply [[TakeOurWordForIt described by Phone Guy]]. That said, the games use [[JumpScare jumpscares]] as a core mechanic. The story for the games features such lovely, child-friendly things as SuckECheeses animatronics coming to life to murder the player character, someone getting serious brain damage by one of the animatronics biting them, [[spoiler:a SerialKiller luring children to the backroom to murder them, followed by their bodies being stuffed into the animatronics so that the spirits could take revenge]], [[spoiler: the killer experiencing a KarmicDeath at the hands of his victims and becoming the third game's antagonist]], and childhood [[KidsAreCruel bullying]] and [[ParentalNeglect neglect]] [[spoiler:resulting in said bite]].
* ''VideoGame/TalesOfSymphonia'''s art style does it no favours. Within the first fifteen minutes there's FantasticRacism and murder abound. Chibi doesn't get much more brutal!
* VideoGame/FunRun is a game with cute, colorful graphics and {{Ridiculously Cute Critter}}s. WhatCouldPossiblyGoWrong? [[TheManyDeathsOfYou Everything]].
* ''VideoGame/{{Darkstalkers}}'': This fighting game may have beautiful, anime-esque artwork and flashy graphics, but this game was clearly ''not'' meant for kids. The game is full of blood, full-frontal {{fanservice}}, morally gray characters, NightmareFuel, complex character stories, symbolism to religious beliefs, and stuffed to the brim with sexual innuendos. In fact, the first villain is a SatanicArchetype and one of the heroes is a nude CatGirl. This was also one of Capcom's darkest games until ''Resident Evil'' was developed. To be fair though, the "M" rating wasn't as strongly present when the game came out.
* ''VideoGame/TheBattleCats'': Although the game has cute cartoon graphics and a simple story, it also features references to bondage-dom couples, numerous Cats that have referenced genitalia, and sexy legs Cats. It being rated "T" should tell you everything you need to know.
* ''VideoGame/CannonFodder'': Despite it's cute designs, it was clearly not for kids as it is a very violence game where you had to shot people to win.
** And even worse. In the North American releases, Atari Jaguar and 3DO versions are rated "E" despite its reasons. It was later re-rated to T when the Game Boy Color version released.
* ''VideoGame/InjusticeGodsAmongUs'' is another superhero game with incredibly heavy mature content that our heroes have to confront. However, that doesn't stop younger gamers from getting actively involved with the gritty story anyway. In the main campaign, ''Superman'' of all characters pulls a FaceHeelTurn and [[AxCrazy goes on a killing spree]], becoming an EvilOverlord conquering the entire universe. For bonus points, the story opens up with the man in blue ''shoving his arm into the Joker'' to avenge his murdered wife Lois Lane and Metroplois. The game features an abundance of blood, morality issues, sexual innuendos frequently dropped between certain characters, and naturally violent moves to act as finishes. It should say a lot that the game was developed by the creators of ''Franchise/MortalKombat''.
* ''VideoGame/LifeIsStrange'' is often confused as a SliceOfLife interactive game dealing with teen drama and the coming of age story about a young girl growing up, but it also features ''loads of dark themes''. While our main protagonist Max does gain superpowers, the story is basically a murder-mystery about teenage girls discovering how a missing girl was abducted, drugged, raped and possibly killed right on a high school campus. Along the way, the player frequently sees gruesome violence, underage teenagers casually talking about sex, attempted suicide, the loss of faith, swear words utilized as half the dialogue, a SadisticChoice once an episode, and the BigBad is revealed to be a pedophile SerialKiller [[AdultFear hiding in Max's high school.]]
* ''VideoGame/TheWolfAmongUs'' has gained quite a bit of interest from younger gamers due to the story being about classic fairy tail characters moving into New York City and having an awesome picture of an [[TheBigBadWolf epic looking wolfman]] on the cover. But in short, the game is ''not'' targeted at younger gamers. The game features gritty violence, explicit nudity, an overall depressing theme, economic social commentary, corrupt politics, serious detective case work, poverty themes, mafia symbolism, and shows how our favorite fairy tale characters [[RealityEnsues did not gain a happily ever after ending]] as was assumed in their stories. Nevertheless, since it's about fairy tale characters it [[{{Understatement}} can't be all bad, right?]]
