* ''VideoGame/BrutalLegend'', oh so hard. Music/OzzyOsbourne, [[Music/{{Motorhead}} Lemmy Kilmister]], [[Music/TheRunaways Lita Ford]], and [[Music/JudasPriest Rob Halford]] show up in the game, [[InkSuitActor are IDENTICAL to their real-life appearance]], and they're not recognized as such by metal uberfan Eddie Riggs.
* A bonus cutscene in ''VideoGame/MetalGearSolid4GunsOfThePatriots'', from TheVerse's [[ShowWithinAShow bizarre television]], shows the actress Lee Meriwether (rather creepily) interviewing the screenwriter David Hayter -- Meriwether and [[FanNickname Dayter]] being the voice actors for Big Mama and Solid Snake respectively. In case we didn't get it, Dayter is dressed in a snakeskin jacket and digital eyepatch, and Meriwether talks to him in the somewhat stilted, poetic, dramatic tones of a ''VideoGame/MetalGear'' character giving an important speech, only addressing him by his full name. Did we mention the ''Metal Gear Solid'' has NoFourthWall?
** More subtly, ''VideoGame/MetalGearSolid3SnakeEater'' mentions many movies which served as an inspiration for the game, and the first ''VideoGame/MetalGearSolid'' ends ([[MultipleEndings if you submit to the torture]]) with Snake openly discussing his ThemeNaming with his new friend, Otacon (they're called [[Film/TwoThousandOneASpaceOdyssey Dave and Hal]]).
** Creator/HideoKojima exists within the ''Franchise/MetalGear'' universe, as a 'legendary game developer', and Otacon is shown to be a fan of his other games ''VisualNovel/{{Policenauts}}'', ''VideoGame/ZoneOfTheEnders'', and ''VideoGame/{{Boktai}}''. But Otacon, despite knowing Meryl and implicitly being friends with her, doesn't recognise Meryl Silverburgh as being an {{Expy}} of a character in ''VisualNovel/{{Policenauts}}''. He also doesn't notice anything strange about the Solar Gun, or the HIDE-CHAN noodles. The weirdness of this is massively dwarfed by the fact that Emma has a ''VideoGame/MetalGearGhostBabel'' poster in her lab in ''VideoGame/MetalGearSolid2SonsOfLiberty'', with Snake on it. ''Ghost Babel'' also had Raiden in it, as well as the ShowWithinAShow ''[=IdeaSpy=] 2.5'', which Snake and Otacon are fans of in ''Metal Gear Solid 4'' and which ''was turned into a RadioDrama voice acted by Hideo Kojima and Yumi Kikuchi'' in the real world. If Snake recognises the resemblance between Yumi Kikuchi and Raging Beauty, he doesn't comment on it.
*** It's possible Emma's poster isn't an example; after ''Metal Gear Solid'', an account of the Shadow Moses incident is made public and denied by the government. The denial is rather flimsy, because Metal Gear REX's blueprints are sold all over the world, so everyone knows the "walking tank" part of the story is true, at least. As a result, Solid Snake becomes a figure in popular culture with many different ideas of what he's really like, or if maybe the government is telling the truth and "Solid Snake" is just a myth playing up on the exploits of real, but normal, military special forces. ''Ghost Babel'' could exist in-universe as a movie or videogame depicting one particular idea of what a Solid Snake adventure would be like if he is, indeed, real.
** During ''Metal Gear Solid 4'', it's never pointed out why Raiden is so protective of Sunny. [[FridgeHorror Maybe it's because he thinks his own child would have been the same.]] [[FridgeBrilliance Or maybe its because she sounds like his wife.]][[note]] Creator/KikukoInoue did the voices of both Sunny and Rose in the Japanese release.[[/note]]
** The Japanese version of ''VideoGame/MetalGearSolidPeaceWalker'' features Creator/AkioOhtsuka, Creator/TomokazuSugita and Yumi Kikuchi (the seiyu for Snake, Miller and Strangelove respectively) as potential MSF soldiers.[[note]]These recruits are in the English version as well, but they're just treated as generic characters.[[/note]]
* ''VideoGame/SuperRobotWars'' loves to play with its HeyItsThatVoice casting like this, with characters mentioning other characters' similar voices, and even making {{Shout Out}}s.
* Wrestling/CaptainLouAlbano played Mario in both the live-action and animated segments of ''SuperMarioBrosSuperShow''. In a particularly memorable live-action segment, Luigi mentions that Mario idolizes Captain Lou, who goes missing. Albano appears at the end of the episode, shortly after Mario leaves...
** In the ''Comicbook/SuperMarioAdventures'' comic serial that ran in ''Magazine/NintendoPower'', the first thing we see Princess Peach doing is playing a ''Franchise/SuperMarioBros'' game.
* In the ''VideoGame/GrandTheftAuto'' universe, California (and possibly part of Nevada) and New York City don't exist, having been replaced by San Andreas and Liberty City respectively, but some of the songs on the radio still reference California and New York City. For example, ''VideoGame/GrandTheftAutoIV'' takes place in Liberty City, but the song list still includes "New York Groove" by Hello, and Bob Seger's "Hollywood Nights" is featured in ''VideoGame/GrandTheftAutoV'', while the in-universe equivalent of Hollywood is known as Vinewood.
** A radio DJ in ''Vice City Stories'' explicitly mentions New York at one point.
** Lampshaded in a Website/SomethingAwful Forum LetsPlay of ''San Andreas'', when the narrator and his friend at one point note Music/SnoopDogg's rapping about Compton is obviously a disguised version of the game's Ganton. And there's a [[MoralGuardians Jack Thompson]] {{Expy}} who thinks that rap music encourages people to violence.
** In ''[[VideoGame/GrandTheftAutoSanAndreas San Andreas]]'', the DJ for the Classic Rock station (K-DST) is voiced by Axl Rose, who often takes shots at the heavy metal/grunge station Radio X. Radio X plays the Music/GunsNRoses song "Welcome to the Jungle."
** ''VideoGame/GrandTheftAutoIII'' contains a billboard which reads "See you in Miami!"
** In ''V'' the song "Convoy" plays on the radio and references Kenworth, Peterbilt and GMC trucks, despite these brands and vehicles being parodied in the game.
* A NPC in ''VideoGame/EarthBound'' says that he is eagerly awaiting the reference of ''[[VideoGame/MOTHER3 EarthBound 2]]''. In another level, a closed building is said to be housing a conference for the developers of ''[=EarthBound=] 2'' as well. A bit HilariousInHindsight, given [[DevelopmentHell what happened to the actual]] ''[=EarthBound=] 2''...
* ''VideoGame/RainbowSix: Vegas'' had a few ''VideoGame/SplinterCell'' arcade machines in it. However, Third Echelon is mentioned as having gathered intelligence for one mission, so ''Splinter Cell'' is probably canon within the R6 universe.
** Maybe Third Echelon or someone else had the games commissioned in that universe so that any reports of the real Third Echelon would be dismissed as made by game obsessed nuts?
* In ''VideoGame/SaintsRow2'', it is mentioned that the character Benjamin King from the first game has written an autobiography, which will be made into a movie where King will be played by his real-life voice actor. In the fourth game, Benjamin King is voiced by [[TheOtherDarrin Terry Crews]] (due to Michael Clarke Duncan passing away) and characters note that the actor who played him in his movie doesn't sound like him.
** [[VideoGame/SaintsRowIV The fourth game]] completely plays this up by having Creator/KeithDavid, who's previously voiced Julius in the first two games, appearing as himself (who's now also Vice President). The similarity between the two is often addressed and is something of a RunningGag.
* Averted in ''VideoGame/AceCombatAssaultHorizon'', where if you use DFM to do a certain stunt, another character will chastise you by directly saying that [[ThisIsReality "this isn't]] VideoGame/AceCombat". Makes a little bit of sense, in that it's one of the few games in the series to take place in the "real world".
* A curious and perhaps unintentional one exists in the continuities of the first ''Franchise/TombRaider'' games in relation to both [[Film/LaraCroftTombRaider film adaptations]]. According to Core's biography, Film/{{Deliverance}} was Lara's favorite movie. In case you don't know, it stars John Voight. Now John Voight plays Lara's father in the first ''Tomb Raider'' movie, and [[Creator/AngelinaJolie his real-life daughter]], of course, plays Lara. This means that John Voight and Angelina Jolie also have to exist within the universe of Core's games, and perhaps even the TR movies themselves. So the movie probably exists within its own continuity. In Lara's [[https://www.youtube.com/watch?feature=player_embedded&v=-RdB66mGPTg promotional interviews]] for ''[[VideoGame/TombRaiderAngelOfDarkness Angel of Darkness]]'', she compliments Angelina Jolie on looking so much like her.
