In Scribblenauts, typing "scribblenaut" will call up the original player character design, which is also unlockable to play as.
Jump Ultimate Stars. Every single action taken by every single character, whether it's a normal punch or one of their super moves, is lifted directly from a certain panel from their respective series.
At one point in the game The Darkness, you can hear someone discuss a fictional movie that he idly mentions has "That chick from Witchblade." In the comics, Witchblade and The Darkness are part of the same universe, and have had crossovers.
And a kid.
The Final Fantasy games are filled with (depending on your perspective) recurring characters and/or Mythology Gags. With the series steadily entering the XIVth title, and sprawling countless spinoffs, Final Fantasy will have a lot of Mythology Gags to count on.
Final Fantasy II features a Dragoon, the first in the series, named Richard/Ricard Highwind; later, Final Fantasy IV would feature a Dragoon named Kain Highwind, and while the curmudgeonly airship mechanic Cid Highwind of Final Fantasy VII (himself being FFVII's incarnation of recurring character Cid) certainly doesn't resemble the traditional Final Fantasy Dragoon, his use of spears and the Jump ability in combat cement him as a Highwind in the mold of his immediate predecessor. Later translations of Final Fantasy II incorporate a new Mythology Gag in the form of Richard's son being named Kain (even though the continuity of the games, or lack thereof, means he cannot possibly be Final Fantasy IV's Kain Highwind), and the most recent translation of Final Fantasy IV brings the reference full circle with a brand-new scene where Kain mentions that his father's name is Richard.
There's also a couple more: an escaping villain taunts the heroes with "You spoony... guys!", referencing an infamous Bowdlerization from FFIV. And a random townsman says a frequent line from the orginal Final Fantasy, "Warriors, bring light to the ORBS!" only for the heroes to respond "Shut up."
Another example is the Job System in Final Fantasy III. You got jobs from each of the Crystals. The first Crystal bestowed the jobs of Fighter, Black Belt, Thief, Black Mage, White Mage, and Red Mage. The exact same jobs that were your choices in the original Final Fantasy. In addition, the final Crystal bestowed 4 of the six upgraded jobs from Final Fantasy, with the mages gaining snazzy new names: Ninja, Warlock, Devout, and Master (Knight was on the second Crystal, and Red Wizard was replaced by the one-man magical arsenal known as the Sage).
The description for the song "Chocobo Chocobo" in the Final Fantasy IV DS Music Player says "They're probably all off playing in some mysterious dungeon now." A comparatively long-running spinoff series for Final Fantasy is Chocobo No Fushigi Dungeon — which translates as "Chocobo's Mysterious Dungeon", although it's usually just called Chocobo's Dungeon in the US. The randomly-generated dungeons in the series are consistently called "mysterious dungeons" in either version.
Final Fantasy X features a "Spoony bard" too, while the Warrior Monks are in Luca. A townsman will tell you that he asked one of them out, "but she called me a spoony bard! Can you believe it?"
Character Job Classes (most noticeably Bartz as a Dragoon featuring a near-identical sprite to Kain from Final Fantasy IV) in Final Fantasy V often feature cues from Final Fantasy III in at least one design. Subsequently, Final Fantasy Tactics features a similar amount of nods, with several generic character sprites featuring identical design features... Most notably the male Monk and male Thief (Bartz) and the female Lancer and Ninja (Faris).
The Advance Remake has Gilgamesh as an Esper. He is once again a sword-collector; he falls for Excalipoor again, and in battle, he uses the same trick he did in Final Fantasy V; namely casting Protect, Shell, Haste, and Jumping.
And another new Esper is Diabolos. His specialty is, yet again, Gravity spells.
The play in the ending sequence of Final Fantasy IX includes the line "No cloud, no squall shall hinder us!" This is one of many such references to the game's predecessors.
When the main character is in a weapon shop he sees a sword on the wall. He remarks that he remembers "a guy with spiky hair" who used a sword like that. The sword looks very similar to Cloud's Buster sword from Final Fantasy VII.
In fact, the game was filled with these, since it was basically a reference to the series as a whole, to wit: the return of the Battle Theme Music that had been last heard in Final Fantasy VI, a sidequest involving characters named Doga and Une, the in-game band's performance of the Rufus march from Final Fantasy VII, the appearances of black mages as faceless people with glowing eyes underneath wide-brimmed hats, which had been avoided (at least for player characters) after Final Fantasy V, and the general return to cartoonish proportions in the character design, which had been eschewed in Final Fantasy VII and Final Fantasy VIII.
Ramuh has you gather and piece together the pieces of a story before he will allow you to summon him. The story is about a quest in Final Fantasy II.
And of course, the Trance powerup, which turns the characters into furred versions of themselves for an incredible power boost, is a reference to Final Fantasy VI's Terra.
Additionally, the Ronso tell Yuna that they'll build her a statue with big horn on her head. Yuna is a summoner. In previous games (III and V, as well as one of the summoners from IX— the other had hers cut off), the summoner class had horns.
Final Fantasy X-2 contains several references to other games in the series, including, on Ultima Weapon's scan data, "Whatever you do, don't call it Atma."
Also there's the enemy named "King VERMIN!", which is named after the insult Barrett used on Shinra.
When Shinra tells them of the huge amount of energy from the Farplane and how, if used, would change a lot in their world, Yuna talks about a huge city that would never sleep...
Which is also a Stealth Pun, since Shinra came up with the idea.
Final Fantasy XI has a bit more elaborate nod to FFI with what are called Artifact Armor. Some of the classes in the game can gain special armor that makes them look like characters from the older games: Fighters got bulky red platemail, White Mages got red-trimmed white robes, Black Mages got the pointy hats, and Red Mages got the distinct red jerkin-cloak-armor and the pimp hat.
On top of that, the 6 jobs new Final Fantasy XI characters initially have available are the same as the 6 possible party members in FFI: Warrior (Fighter), Monk (Black Belt), Thief, Red Mage, White Mage, and Black Mage.
When Gilgamesh fights you in Final Fantasy XII, he breaks out a number of other Final Fantasy swords over the course of the battle. His version of the Buster Sword is marked "Replica" in kanji on its side, which makes a lot of sense for someone best known for wielding the "Excalipoor".
Final Fantasy Tactics A2 has a scene where Luso accidentally bumps into a Bangaa and almost calls him a lizard... the same mistake that his predecessor Marche made in the first game. Fortunately, a moogle prevents him from saying it. As it turns out, its Montblanc, the same Moogle that helped Marche.
And there is Hurdy, a Moogle bard. His starting abilities include hiding at low health. It would seem that his mentor was Spoony Bard Edward of Final Fantasy IV fame.
And Hurdy has a twin sister named Gurdy, harkening back to Hurdy and Gurdy from Final Fantasy Crystal Chronicles (even though there is the implication that Hurdy and Gurdy are actually the same person)...
Chocobo's Dungeon has a dungeon filled with Cactuars and Iron Giants. The song playing in the background is a remix of the song playing in the Thunder Plains from Final Fantasy X, an area filled with said monsters.
Some character intros will have clear references to events in the other games: for example, both Cecil and Golbez will make reference to the fact that Gabranth is going through the same pain they have. On the lighter side of things, Kefka will tell Tidus to "go back to the beach already..."
Summons will reference appearances in multiple games if they have different forms by using different artwork for each one.
Kid Icarus: Uprising, being developed and released about twenty-five years after the NES original, has a variety of Mythology Gags and Call Backs. In one instance, Palutena jokes with Pit about how he used to cry "I'm Finished!" all the time, to which Pit replies "I...still say that...a lot." And sure enough, the top screen does read "I'M FINISHED!" in the event of a Game Over.
Another end battle quote by Cody is "No matter what happens, this will not be my Final Fight!"
In the same game, Sakura Kasugano says she likes "street fighting" as compared to "sparring in Rival Schools". Sakura made a playable cameo appearance in the first Rival Schools.
Dan Hibiki also claims that "I hate the art of fighting, but I want to be king of fighters!" In a previous game, he asked Ken whether he knew "the art of fighting", as well. Dan is based on Ryo and Yuri Sakazaki and Robert Garcia of SNK's Art of Fighting and King of Fighters games.
Street Fighter IV's incarnation of Dan features him performing the Hao Sho Kou Ken motion from Art of Fighting very slowly if he is left standing still long enough. And in Super Street Fighter IV he gets an Ultra move that is a blatant copy of the HSKK.
A translation error in the original Street Fighter II arcade game had one of Ryu's win quotes as "You must defeat Sheng-Long to stand a chance." Sheng Long is the Chinese reading of the first two characters in Shōryūken, one of Ryu's signature techniques, and Sheng Long was turned into an April Fools' joke by EGM. In a trailer for Super Street Fighter II Turbo: HD Remix, at the end, after Ryu attempts to chase Akuma, it shows a cryptic, soundless piece of text, simply saying, "You must defeat Sheng-Long to stand a chance..."
And then when Ryu and Ken's actual master, Gouken, was added as a playable character in the home versions of Street Fighter IV, he ended up having, in one way or another, every single move the original April Fools' joke claimed he had.
The alternate costumes in Street Fighter IV are occasionally Mythology Gags. For example, Zangief's alternate costume is Mike Haggar. Super Street Fighter IV seems to be going even further into it: Zangief gets Mecha-Gief, and, one of the most clever connections in the series, Bruce Lee homage Fei Long gets Kato as an alternate costume.
Super Smash Bros. is an entire game series built on Mythology Gags. Many of them are obvious, but the sheer amount of reference to Nintendo's origins is baffling. Everything from random items in the background of stages, to the particular designs of items and character's individual moves. Just look at the History Behind Smash Bros series.
In Brawl, Snake's Codec conversations are full of references to Metal Gear Solid that weren't present in his stage. In addition to whole slew of other things, he compares Ness to Psycho Mantis, Pikachu's electricity to Revolver Ocelot's torture device, and references Big Boss and Liquid when talking about Link's Legacy Character status.
In the Subspace Emissary mode of Brawl, Ness uses PK Flash to blow up the seemingly invincible King Statue in a cutscene. This is a nod to the fact that said move was one of the few ways it could actually be defeated in MOTHER 3.
In Metroid: Other M, one of Ridley's attacks involves grinding Samus against the wall. This is how he introduced himself in Brawl, released at least a year prior.
One of Brawl's music tracks is a medley of the map screen and bonus room themes from the original Donkey Kong Country, the latter possibly because of Donkey Kong Land using the theme for its map screen.
Little Mac's trailer includes him standing next to Samus, where she compares her size with his. When you look at his Assist Trophy page on Brawl's Dojo, it mentions how short Mac is, and standing right behind him for a comparison is Samus. His artwork for the fourth game shows him in a Punch-Out!! arcade machine fighting Donkey Kong, who was the bonus boxer in the series' Wii reboot.
The upcoming 3DS version of the fourth game has an exclusive multiplayer mode, "Smash Run", where up to four players run about a large open dungeon and fight various enemies to collect power-ups that are tallied at the end of five minutes for a one-minute long winner-take-all fight. This mode combines elements of Brawl's "Subspace Emissary" with the City Trial mode from Kibry's Air Ride, another game Masahiro Sakurai developed.
The mobs found in Smash Run draw from almost every game represented in Super Smash Bros., plus a few other games not represented. These include (but most certainly do not limit to) Kremlings, Eggrobos, Mettools, Sneaky Spirit, and even a few enemies from Brawl 's Subspace Emissary.
The theme song for the multiplayer results screen following the winner's victory fanfare is an arrangement of the character select screen from the original SSB.
One of Mega Man's victory poses is a match for the pose he struck on the title screen of the original Japanese version of Mega Man.
The North American localization of Persona 3 contains an in-game MMORPG that's a giant mythology gag to the first two Persona games. The game is named "Innocent Sin Online", after Innocent Sin, the subtitle of the first half of Persona 2 and a game that was never released in the West until the remake for the PSP was released in 2011. When you first log on, you get a message from Phil. — short for Philemon, a major supporting character from the original Persona series. You start off in Lunarvale Hospital — Lunarvale is what the city in the original Persona was named for the US release, and its hospital was the first dungeon. A girl you meet in the game suggests you name your character "Tatsuya", and renames herself "Maya", the protagonists of Persona 2: Innocent Sin and Eternal Punishment respectively, and major party members in each other's game.
In the original Japanese version, the game was called "Devil Busters Online" and the MMO characters were named "N-jima" and "Y-riko", which were references to Digital Devil Story (the books that started the whole MegaTen franchise), the original Megami Tensei game (which was a direct video-game adaptation of the first of the novels), and Megami Tensei II (the first MegaTen game to draw themes from the novels without being directly based on them). Understandably, the references were changed for the English release due to the fact that even most Western MegaTen fans wouldn't have gotten the joke back in 2007.
At one point you hear rumours of a ghost haunting the local shrine. The same rumours circulate around the shrine in Innocent Sin, and in fact they are a major plot point. And at another point, someone rubbishes the idea of rumours becoming reality, which is exactly what happens in Persona 2.
And at another point, there's a brief mention of the Kirijo family once belonging to the Nanjo Group. Nanjo was a character from the original Persona — Nanjo was his family name — who was roughly equivalent to Mitsuru, although his rich family was much less plot-relevant.
During the King's Game Scene (which just so happens to take place in the "Club Escapade" nightclub from Persona 3), Chie compares Naoto to a detective from a film she once saw. The detective in question? Kuzunoha, of the Devil Summoner series (not to mention Persona 2!). It just so happens that Naoto looks a lot like a certain Devil Summoner.
Note that this particular gag is solely a product of the North American localization; the original Japanese was a reference to the Kindaichifamily, which would be equivalent in the English-speaking world to a Sherlock Holmes reference.
During that same scene, Rise mentions that a surprise midnight performance at the same night club was canceled due to a power outage. If you played Persona 3you can probably guess what happened... (Apparently the P4 cast can't experience the Dark Hour...) The rest of the Port Island sequence is mostly filled with overt references to the previous game as well.
The Entire Void Quest Dungeon is full of these, particularly in the boss fight against Shadow Mitsuo, which directly lifts attack menus from the original Megami Tensei.
Not to mention one of the floor dialogues has Mitsuo's mother lift lines from the protagonist's mother from Shin Megami Tensei I as well, mentioning sirens keeping her awake and a request to buy coffee. Whether it really happened or if it's another twisted manifestation isn't entirely clear. It gets even creepier when the next floor twists the dialogue.
Another one that probably will go unnoticed, is that the maximum XP you can gain in a single fight is 65535. That's the same number you gain from fighting Lucifer in Nocturne, which was a Mythology Gag in itself.
The original Persona contains a mythology gag itself: at the beginning of the Snow Queen quest, it's mentioned that minor character Tamaki (a student who recently transferred to the protagonist's school from her old one) is quite knowledgable about demons; if you talk to her yourself, she'll hand you a rapier and say that she used it for some stuff at her old school. Tamaki was the female protagonist of Shin Megami Tensei If, the game that the Persona series spun off from.
Star Wars Battlefront II has some of these in the random dialogue that comes up during battles. Of note are:
Imperial Stormtrooper: "It's Obi-wan! Shall we put a disturbance in his Force?" (A reference to his famed 'disturbance in the force', of Episode 4)
Imperial Stormtrooper: "It's Solo! And he's shooting first! That's not fair!" (A reference to the Han Shot First debate)
Clone Trooper: "Its Darth Maul! What's he going to do, bleed on us?" (A reference to Maul's unfortunate demise before doing anything more significant than killing one maverick Jedi, as well as being a Shout-Out to Monty Python'sBlack Knight)
Imperial Officer: "You Rebel scum!" (direct quote from Return of the Jedi)
Held captive and asked where the Jedi enclave where you received your Jedi training, you can say it's on Alderaan, when it's really on Dantooine; an inversion of Leia claiming the Rebel base was on Dantooine in an attempt to spare her home planet of Alderaan.
At one point a character mentions that her husband's Sith-killing days were "a long time ago, in a war far, far away."
On Tatooine, you need to use bantha fodder to lure banthas into a cave as bait for the Krayt dragon living inside, and you can tell the NPC you're working with, "Look, I have your fodder."
There is also an easter egg (after getting the Light Side and Dark Side endings, then starting another game as a female character) where Atton says something like "Are you an angel? Wow that was bad, I hope some stupid kid doesn't end up using it." when you enter the cell block on Peragus.
There was another one that was cut from the game, where Atton says he shouldn't even be in the game and was meant to star in a spin-off of Jedi Knight - namely, Jedi Academy, which came out around the same time.
Once you've trained Mira to be a Jedi, it is possible to tell her that she has "taken [her] first step into a much larger world," which is the same thing Obi-Wan says to Luke in Episode IV.
When you've influenced Handmaiden to become a Jedi, she says "I want you to teach me the ways of the Force. To become a Jedi Knight like my mother," which is very similar to a line spoken by Luke.
Also in the second game, when General Vaklu expresses his shock that you are still alive, one of the possible replies is "You'll find I'm full of surprises" (a reference to The Empire Strikes Back).
In the comic, Mandalore has the same mask which the random Mandalorian soldier was seen picking up in the last pages of the penultimate Tales of the Jedi story arc.
On Taris, you have the chance to fight a Mandalorian going by "Bendak Starkiller".
At various points on Paragus, the player has an option to quote lines Luke, Han, or Leia made in the original movie. You can ask a droid if he can "teleport me off this rock"(Luke), ask Atton if he would prefer it back in his cell(Han), and comment on going into danger that "somebody has to save our skins"(Leia).
For example, in Full Throttle, nosey reporter Miranda begs main character Ben to help her:
Miranda: Well, I tarcked the guy to Melonweed. But I'm not going near the place! They'd kill me! Get my editor! He's got to get me out of this! Take one of these fake IDs to get through the roadblocks. My career is riding on those pictures! Help me, Ben, you're my only hope!
Almost ALL of the Monkey Island games have an option to say "I'm selling these fine leather jackets", from the Indiana Jones Last Crusade game.
And the man who drives the fertilizer truck has the Imperial insignia tattooed on his arm.
While filming Raiders of the Lost Ark in Cairo, the producers had everyone take down their TV antennas so they wouldn't show up anachronistically in a rooftop scene. In the corresponding level of the Lego Indiana Jones video game, you can find a secret room filled wall-to-wall with satellite dishes.
Similarly, in Lego Star Wars, there is a secret room where you can put on Indy's fedora. Naturally, Han Solo can do this as Harrison Ford played both characters.
In Dawn of Sorrow you can collect Konami Man, a Bell, and a Crown, which all have descriptions telling you how many points they're worth. All three come from the very first Castlevania, where they were hidden items that you obtained by performing certain actions in certain places, which is the same way you obtain them in Dawn of Sorrow. You can also obtain a rosary as an equippable item: in the old games, it was an item that wiped out all enemies on screen if you touched it.
In Aria of Sorrow, the save room contains a half-buried coffin — it's the same coffin Alucard uses in Castlevania: Symphony of the Night as part of the game-saving animation.
Various games of the series also include skeletons of bosses of other episodes as wall decorations every now and then, with Slogra and Gaibon being the most popular.
Castlevania: Symphony of the Night also features another of these "remember that older game?" jokes — when Alucard meets Maria for the first time, she mentions that she's looking for Richter Belmont. We are then shown two comic-book style 'thought bubbles', Maria's containing a sprite of Richter, and Alucard's — of Trevor in all his 8-bit glory from their team-up in Castlevania III: Dracula's Curse.
Shanoa has a catchphrase that she uses in both Order of Ecclesia and Judgment: "I am the morning sun come to vanquish this horrible night". This is heavily based on the message that appears when the sun rises in Simon's Quest.
The name of the Bionic Commando podcast is a mythology gag — it's called "Top Secret", which was the original Japanese name of the Arcade and NES games that started the franchise.
Two of 'em in the 2009 game:
At the Avenue of Heroes. The statues of "RAD" Spencer and "Super Joe" Gibson are dated 1989 and 1991 respectively — one year after the release of the NES Bionic Commando, and Mercs. (The first game to refer to "Super Joe" by the name Joseph Gibson)
Near the end of the game, a frustrated General Armstrong asks Spencer if he thinks he's a "damn fool", in reference to one of Hitler's line in the NES game.
Bionic Commando Rearmed 2 has a sign for "Club Explod", in reference to an infamous typo in the English translation of the NES game.
Papetoon was mentioned in the Japanese manual for Star Fox 64.
Every game in the Dragon Quest series contains some variation on either "No response. Looks like a corpse." (Translations for Dragon Quest VII and earlier), or "No reply. It's just a corpse." (Newer translations, because consistency in mythology gags is for losers) This is a call back to the original Dragon Quest, where, during the now-traditional Playable Epilogue, you could visit a soldier who had been injured for the rest of the game and receive this response — the one downer element of the Happily Ever After.
The English translation of the DS version of Dragon Quest IV features some mythology gags regarding the name changes in the translation of the original NES version. The character Ragnar, who was named Ryan in the Japanese, now has the full name Ragnar McRyan, while the full name of Torneko, who was renamed to Taloon in the NES version, is now Torneko Taloon.
In Mega Man Legends 2, a TV in a bar displays a short looped animation with Guts Man, Proto Man, and the original Mega Man. A poster in the same city displays Zero prominently.
The Zetsabre (Z-Saber), a part necessary to complete one of the game's strongest weapons is referred to as "A weapon of a legendary hero". To get it you must ether pass a 100-question exam or hand over 3 million Zenni, but it's worth it due to the Gamebreaker damage levels of the Blade Arm.
If you listen to Blues's theme in the Gaiden GameRockman.EXE 4.5: Real Operation, the opening tones sound exactly like Blues/Protoman's whistle from the original Mega Man series.
The 4.5 PET theme of every Navi based on a Robot Master is a remix that Robot Master's original Empire Theme. Blues' is the Blues Whistle in its entirety, and Forte's BGM is the Forte riff from Mega Man 7.
In a reference to the mistranslation of Dr. Light as Dr. Right in some early Mega Man games, the equivalent doctor in Battle Network is named Tadashi Hikari, which means Right Light in Japanese.
Don't forget that about half the characters are inspired by the original Robot Masters. Guts Man comes to mind.
Used as a Brick Joke in Sonic Generations, where Sonic's special present is a chili dog, but he doesn't get to eat it before the Big Bad attacks. At the end of the game, he returns to his time and catches the dog, which is still warm.
The Elder Scrolls IV: Oblivion simplified Morrowind's armor system by combining the pauldron slot with the cuirass. They nod to this in the Shivering Isles expansion, where a local smith's shop is called The Missing Pauldron. This also refers to how Morrowind's Daedric set was, for quite a while, missing one of its available pauldrons until an expansion came out.
There's also M'aiq the Liar, whose entire dialogue is filled with mythology gags.
Starcraft has Jim Raynor seeing the purple goo stuff that emanates from Zerg colonies and saying "What the hell is that!? Looks like the ground there is alive!". Warcraft III, meanwhile, has Jaina seeing the corrupted stuff that emanates from Undead colonies and saying "It looks like the land around the granary is... dying.".
In Silent Hill 3, the player is given the option of having the protagonist reach into a filthy (even by Silent Hill standards) toilet to search for anything useful. She refuses to, and a cutscene plays in which she looks directly at the camera and says "Who could do something so disgusting?", referencing the protagonist of the previous game who did do without hesitation, which remains a frequent joke at his expense among the fandom.
In Silent Hill 4, Henry shows a similar aversion to toilets, saying "now is not the time for this kind of thing", despite showing no reservations about going into dangerous/disgusting places otherwise.
'In The Legend of Zelda: Twilight Princess, Link takes special lessons from a character known only as the Hero's Shade, a skeletal figure accessible in a sort of dream world. It's never directly stated in-game, but it was eventually confirmed that this is the Hero of Time, the Link from Ocarina of Time.
Also in Twilight Princess, the six Sages found in the desert have the same symbols as their Ocarina of Time counterparts did, even though they are completely different. The Temple of Time also has the same music in the entry area as its older version, despite being located somewhere else.
Not to mention that some of the melodies you have to howl as a wolf to obtain the secret techniques are, ostensibly, the ocarina melodies.
The one melody is "Ballad of the Gales", the bulk of which is derived from "Minuet of Forest". Each Howling Stone song seems to share emotional significance to OoT Link. "Song of Healing" is the central melody of "Saria's Song" backwards and is important in Majora's Mask. "Requiem of Spirit" is the warp song to the final (in storyline order) Temple in OoT. "Prelude of Light" is the first warp song and likely the one used right before the final dungeon. "Zelda's Lullaby" can be considered the most important in-story theme in the series. And the "Light Spirit's Theme" is the theme of the Shade's protege, TP Link.
Also, that you get to visit a ruined version of the exact same Temple of Time from OoT; when you go into its past, you get to see a graphically improved version, complete with the same music, that contains an expansive dungeon.
Considering that the Temple of Light was originally supposed to be a playable dungeon in Ocarina of Time, the dungeon in Twilight Princess itself might as well be another example.
It also has stuff like two seperate characters that say 'It's a secret to everybody' as a reference to the first game and a ton of remixed music played by Kakariko Village's bard among other things (including the Ballad of the Goddess from Skyward Sword). The game's littered with these.
In the intro of Super Mario 64 DS, Yoshi is first seen sleeping on the roof of the castle. The roof was where Yoshi was found in the original Super Mario 64.
I Have No Mouth and I Must Scream includes a mention of the insane supercomputer AM torturing one of the protagonists by coaxing him into walking through a thousands of kilometers of ice to reach a pile of canned fruit, only to discover that AM didn't give him a can opener. This is nearly the entire plot of the original short story the game is based on.
At the beginning of Ted's scenario, an enormous bird can be seen flying past. The short story had AM manifesting itself as great, bird-like monsters to torment the humans as they crossed the frozen wastes.
The Fist of the North StarPS2 fighter lets the player recreate some of the anime series' most famous events. For example, if Shin is losing to Kenshiro on the Southern Cross stage, Shin can pull off a self-inflicted Fatal KO, a recreation of Shin's death in the series.
There are others, as well. Ken's timed-death move does not work on Souther, Rei's instant kill is different when done to Juda or Mamiya, Mamiya's instant kill is different when done to Rei, Jagi's instant kill is different when done to Ken, Ken's instant kill is different when done to Jagi, and so on. But then, considering that about 75% of the special moves are taken from specific scenes in the series (such as Raoh's foot-stab or Jagi's pillar attack), the whole game really is a series of massive shout outs and mythology gags.
In Elite Beat Agents, the actor from Makes no Difference is actually from Osu! Tatakae! Ouendan, the game EBA was based on. This is actually less subtle than most other continuity nods, as he even does the arm waving thing. Also, in The Anthem, the kid's friends are Ted from Highway Star, and the boy from Walkie-Talkie Man. OK, if we were going to list all of these, we would have a pretty big list (Sam is in almost every stage though). Most of them also qualify as an Early-Bird Cameo.
There are actually a lot of very brief blink-and-you-miss-it cameos of characters from Ouendan, as well as for the EBA cast themselves. It's guaranteed that you'll see characters from the later stages appearing in the early stages. It would be a very big list if it was made.
The good endings' credit sequences in Bubble Memories has Bub and Bob using their parasols, which they've also used in Parasol Stars. Both games are in the Bubble Bobble series. Although both may be Non Linear Sequels, Memories apparently takes place after Parasol Stars but before Bubble Symphony.
Though the various settings in Command & Conquer are quite different, with confusingly varying timelines, there are often references to events that have taken place in previous games.
In Red Alert II, General Carville remarks that the Soviet Union is sending a naval force to take Pearl Harbor, and then snickers at the thought of anyone ever succeeding at attacking the base. This is a reference to the first Red Alert, which had a completely alternate World War II where the Japanese never attacked Pearl Harbor.
But when you actually play the mission, the sunken Arizona, complete with memorial, lays in the harbor...
While the series' concept of canon is very loose, it is common fan conclusion that the Japanese-American war in the Pacific still occurred, albeit on a smaller scale.
In Red Alert 3, another mission is set at Pearl Harbour... only this time, you're the Japanese, defending it against a surprise Allied Strikeforce. The mission intro even has George Takei expressing his vehement disbelief that anybody would ever attack the heavily fortified Pearl Harbour.
Also from Red Alert 3 (which takes place in a different timeline than the earlier games) a Soviet mission starts by showing Tanya destroying dreadnaughts and talking about "old times", exactly the same way the Allied campaign starts in Red Alert 2.
The Allies' Mission Control is always named Eva, as a reference to the mission control AI EVA (or Electronic Video Agent) from the Tiberian series of games. Likewise, she has a rivalry with Allied commando Tanya over the affection of the Allied commander.
In Tiberium Wars, though the insidious Tiberium has evolved into completely new forms with new methods of expansion, nods to the original Blossom Trees from earlier Tiberium games can be seen throughout the Red Zone maps, in the form of withered but recognizable Blossom Tree husks.
Also, the game's entire Database holds subtle references to characters and events from the previous games. The game also has a statue of Havoc, the commando from Renegade. The Novelization also makes references to Tiberian Sun, even going so far as having the GDI player character, Micheal Mcneil, as a character. In a "criminal dossier" from the game designer's, a even subtle reference to Red Alert is made.
In Tiberian Sun you can find an abandoned GDI base made from buildings found in the first game, as well as functional mammoth tanks.
In Renegade a cutscene shows that the GDI controls their troops with the exact interface the player used. In fact, it shows part of an actual mission in the original game, then switches to the game level with the exact same layout. Several audios were also taken over, such as the death sounds of Nod infantry or EVA lines like "reinforcements have arrived". During the credits, the same "news" that were shown during the GDI ending also play here.
Many of the same units in the various sequels end up being Expies of themselves — for example, you can pretty much count on any future Red Alert sequel having the Kirov airship, and the Devil's Tongue flame tank down to its name is a link from the first and second Tiberium games in the form of a continuity nod.
Many commando units in the series will have similar lines to the first commando in Tiberium Dawn, including Havok making a reference in Renegade, "Just doesn't seem fair, does it? Maybe I'll shoot left-handed."
Super Robot Wars is rife with these, especially in the OG continuity. The first such occurrence is in Super Robot Wars Original Generation 2: Ryusei Date jokes about renaming the SRX "Dairyusei", or maybe "Dairaioh", when teammate Raidiese F. Branstein protests. The actual Dairaioh later appears in Alpha 3 as a completely different machine.
The Updated Re-release of Original Generation 2 has Lemon Browning mention people other than Beowulf/Kyosuke Nanbu who use the "Wolf" moniker, foreshadowing the appearance of Hugo Medio and Albero Esto (members of a team called the "Cry Wolves") from MX. Sure enough, the Cry Wolves appear in Original Generation Gaiden.
In Original Generation Gaiden, Aqua Centrum appears and says she'll never wear anything as Stripperific as Lamia Loveless, a nod to the fact that in her debut game MX, she actually wears an outfit even more revealing. In the same game, the epilogue has Axel Almer reference the Shadow-Mirror's "Project EF", a direct nod to the spinoff OG Saga: Endless Frontier.
When playing "Yellow Submarine" in Rock Band: The Beatles, the dreamscape depicts the band wearing the same clothes as their animated versions in the film of the same name. Similarly, the song "Sgt. Pepper's Lonely Hearts Club Band" depicts the eponymous band performing in Pepperland.
A literal example occurs in Grim Fandango, when Manny can examine a statue of the first boss at the Department of Death, who was before his time, but supposedly a "real slave driver." Since the game takes place in a very strange version of the Aztec afterlife, this first boss would be Mictlantecuhtli, who was, to put it mildly, a greedy, sadistic Manipulative Bastard.
The Spaceship itself is the exact same ship as the one launched in the Civilization III Space Victory.
In Rockstar's Bully, one of the classes that the protagonist takes is an autoshop class. While only allowed to work on bicycles himself, the cars that the seniors are working on are strikingly similar models to cars that appeared in Grand Theft Auto: Vice City.
Mythology Gags run rampant in the Tales Series. Some examples:
There's always a coliseum where you'll run into characters from previous games.
You can dress characters in the costumes of previous game characters.
Each Tales game has a canon set of items, like the gels/gummies.
There's a secret island in most games, usually run by Katz, containing Mythology Gags for the series as well as references to Namco-Bandai's other work. In the version in Tales of the Abyss - Nam Cobanda Isle - you can find Lloyd Irving's clothes in a storeroom.
In Tales of Vesperia, there are enemies based on the characters Luke, Tear, and Mieu from the preceeding game, Tales of the Abyss.In the PS3 version, new character Patty Fleur can summon Mieu and Quicky with her Mystic Arte.
There are also several bits of graffiti in Vesperia left around from the Tales of the Abyss cast. Cecille <3 Frings is scratched into a wall in Yormgen, you can find descriptions of each of the playable characters carved into the back of a sign in Nordopolica, and there's a note that says "To Asch, From Natalia <3" in a pair of shoes.
A character named Tokunaga has appeared in at least two of the games, as Anise's puppet in Tales of the Abyss and as the captain of the ship the Fiertia in Tales of Vesperia. Tokunaga is also the butler/caretaker for Seles (Zelos's sister) in both Tales of Symphonia games.
Badly-drawn wanted posters have cropped up as a Running Gag throughout the series. So far Lloyd,Yuri, and the Xillia protagonists have been subject to this. In Vesperia, there's also a poster advertising a contest for "who can draw the best Lloyd."
The Legendary Pirate Aifreed is references in numerous entries to the game, and his treasure is sometimes available to find.
One of the Gentleman bosses in Tales of Hearts, himself a walking Shout-Out to Katamari Damacy, will attack you with "Tales of Rollup", where he rolls a katamari of Tales references over you, including Swordians, several common Tales items, Tokunaga, and Mieu.
Dhaos and his aversion to the classic lightning spell, Indignation. Get him to half health and it's an instant kill in all his cameos. He also makes it a note to recite his classic line of "Sonna... Sonna baka na!" right before he gets owned by it. Made more then a mythology gag in the PS3 version of Tales of Vesperia, where Rita will suddenly learn and use the spell out of the blue if she casts Thunder Blade on him under the right conditions, just so she can nuke him out of existence. She can use it on anything after that.
A series of weapons available in Tales of Gracesf are named after past Tales games, and also have designs based on things from the associated game. Hubert's Brave Vesperia is perhaps the most recognizable, essentially being a much smaller, dual-bladed version of the feather sword Yuri used in the finale to cleave the Adephagos in half.
And then there's the absurdly hilarious statue of Kratos outside the Barona Knight Academy.
Early in Fallout 3, a bully and his gang demand you turn over a sweetroll you received as a present. This is a recurring situation from the The Elder Scrolls's character generation process.
Fallout 2 contained many nods and references to its prequel, but some of the funniest were in the water chips. In the first game: MacGuffin. In the second: They come in packs of five, you can find over 100 in an area barely a quarter into the game, and a portal into the past causes the PC to create a Stable Time Loop by breaking the chip from the first one...
Ghostbusters: The Video Game includes tons of subtle references to the past movies — for instance, you can find Vigo's painting and listen to him talk smack to you — as well as other Ghostbusters-related media: If you look closely at the computer at the Ghostbusters' headquarters, you can see the infamous A Winner Is You ending screen from the Ghostbusters NES game on the monitor.
All of the trophies/achievements are references to lines from the movies, as well.
In Pokémon Diamond and Pearl, you have the news report on a red Gyarados, as well as a reporter who claims he covered the story. Also, before Jasmine's cameo in the Gen IV games, you can see her in the audience of Pokémon Contests in Gen III.
In the games, certain character elements have been brought over from the anime, along with other stuff. Brock asks for a Bonsly in the remakes of Pokémon Gold and Silver, Togepi cry whenever they enter Misty's Gym and you talk to them, Misty acts Tsundere in the Johto games, etc.
The games have lots of recurring elements. There's the basic plot which revolves around getting eight badges and such, but there are also other minor elements, either straight from Gen I or from Gen II onwards:
Trio of legendary Pokémon of different typings, and several other legendary Pokémon not belonging to the trio
Pseudo-legendary Pokémon: they have specific stat totals - higher than other Pokémon, lower than all legendaries; they are catchable in any amounts but only in one location, they rely on Magikarp Power and evolving them takes long.
Some of the older Pokémon, even the ignored ones like Aipom, suddenly getting new evolutions in later generations, is very explicitly a mythology gag as well.
There are numerous recurring NPC Trainer themes, from helpless trainers getting pulled all over the country by their energetic pokemon, to unlucky (female) Swimmers who have suffered wardrobe malfunctions or ask where they could keep their pokeballs while they're in their swimwear, Youngsters who have a fixation on wearing shorts that are comfy and easy to wear, and even Psychics who try to divine you and your team's strength.
In Black 2 and White 2, Bianca uses a Musharna, a Mienfoo, and a Stoutland when she fights alongside you at Reverse Mountain. Her Musharna appeared in the previous game, but her use of Mienfoo and Stoutland appear to reference her anime counterpart's infatuation with Fighting-type and cute Pokémon (respectively).
In Backyard Sports: Sandlot Sluggers, Kiesha Phillips, Pablo Sanchez, and Vicki Kawaguchi have their nicknames from the first games, before the Continuity Reboot.
Ecco the Dolphin : Defender of the Future features occasional references to the original games; Hanging Waters in particular is packed with them. The level itself is the 3D version of the Skyway, the squid may be referencing both the Eight-Arms and the flying medusa all in one go, and the giant bird towards the end calls the helpful pteranodon to mind, right down to how he's summoned with song.
Also, in Mass Effect 2, several of Tali's battle quotes are "Go for the Optics, Chiktikka!" which is a Shout-Out to the Baldur's Gate character Minsc, who sometimes will shout, "Go for the Eyes, Boo" before battle, as well as "Nothing is faster than Chiktikka vas Paus", which is a pun on one of Aerie's, another Baldur's Gate character, battle quotes, where she says "Nothing is faster than Chiktikka fastpaws." Another gag is found on the Citadel, where one can purchase a "Space Hamster", which is the name of the species which Boo (purportedly) belongs too. The hamster even gets a special appearance in the Citadel DLC for Mass Effect 3, assuming you caught it on the Normandy...where, if you interact with it enough, Shepard will advise it to go for the eyes if anyone messes with it.
Another example: If importing a Mass Effect 1 character to Mass Effect 2, when Shepard first reunites with Liara on Ilium, she will tell the man she is speaking to "Have you ever faced an asari commando? Few humans have!" which is the same thing Matriarch Benezia tells Shepard when you faced off against her in the first game.
Miranda's loyalty mission contains a scene in which she punches the control panel in a slow cargo elevator and demands to know why it won't go faster, a reference to the infamously slow elevators in the first game.
Similarly, Garrus will reminisce with Tali about the long elevator rides and the conversations they used to have, to which Tali threatens him with her shotgun. The final DLC for Mass Effect 3 confirms that Garrus was the only member of the original squad to enjoy the elevator talks. The rest share Tali's opinion.
Near the end of Leliana's romance arc, you can tell her "You're cute when you're embarrassed," if you feel like making a Knights of the Old Republic reference.
There is also a woman by the name Edwina running a tavern in Denerim, which is a reference to Edwin's ending in Baldur's Gate 2, In which he gets turned into a woman by Elminster and ends up running a tavern under the name Edwina
Dragon Age II contains a dwarf named Varric bearing a crossbow by the name of Bianca. One of the designers commented in an interview that Mirabelle was already taken.
This made it into a bit of party banter; Merril asks about the origin of the name, and says she must have been named after someone. Varric replies that Mirabelle was already taken.
During Merrill's romance in Dragon Age II, she interjects "is it getting hot in here?" into her dialogue in the exact same way Tali does in similar circumstances in Mass Effect 2.
When telling Bethany about her sexual escapades, Isabella lists men, women, elves... and a dwarf in drag, referencing one of the surprise options at The Pearl in Dragon Age: Origins.
Romancing SaGa: Minstrel Song has these in the Children's Section in the Melvir Library. One tale references the infamous Saw glitch from Makai Toshi SaGa (aka The Final Fantasy Legend), another one reference the 7 heroes from Romancing SaGa 2, and another possibly referencing one of the SaGa Frontier games or Romancing SaGa 3.
If you get a chance to look closely at the back of one of the "Chocobites!" cereal boxes in Left 4 Dead, you'll notice it advertises a six-inch Team Fortress 2 action figure inside. "Collect all 10!"
And of course the "I love steam" line in "Crash Course."
In development, Bill was to share his last name with Half-Life's Barney Calhoun.
Transformers: War for Cybertron has some G1 nods. At one point, in the Kaon prison, an Autobot prisoner is pronounced guilty and thrown into a casket. He responds with "Spare me this mockery of justice!", the same quote from when the Quintessons sentenced Kranix the Lithone to Sharkticons in the original movie.
In the Soundwave boss fight, Rumble repeats one of his lines from the original movie: "First we crack the shell, then we crack the nuts inside!"
When Optimus and company have a face-to-face encounter with a space slug (It Makes Sense in Context... sort of.), Ironhide tries the Universal Greeting.
More or less every line and every achievement in the game is a reference to some previous character, characterization, line, song, toy gimmick, or storyline. Every slagin' one.
Saints Row 2, as seen in one of the advertising screenshots, has a billboard advertising a military-themed restaurant called "Company of Gyros".
In Trinity Universe, upon hearing that Lucius and Violet are not into anime, Flonne tries to introduce them into one. The series in question? Disgaea.
Nippon Ichi has managed to include a few small gags in the Disgaeaverse, regarding Etna's standard pose portrait in the original game. Whenever she wasn't talking or was in a neutral mood, the game would show her leaning forwards in a somewhat awkward position; in the PSP port she complains about back pains, and in the prinny games she constantly rubs her back when stunned.
In the Disgaea 3DLC, one of Gig's Evilties (abilities) is that he can Magichange into a weapon, and then when his turn runs out; he turns back into a humanoid; while the person who wielded him is temporarily replaced. In Soul Nomad & the World Eaters Gig spends most of his time as a magic weapon trying to do this.
The back wall of the pawn shop in King's Quest VI holds many items that would have been very helpful to players of previous King's Quest games.
Dynasty Warriors 5 had a nod back to the previous installment during the Wu Zhang Plains stage: After seeing Zhuge Liang's star fall, Sima Yi gleefully rushes the Shu camp, but stops when he gets there, spooked at the sight of Zhuge Liang. Unlike the last game, it's not just a ploy; he shakes his head, and realizes it's actually Jiang Wei, who has taken up Zhuge's mantle.
You were told in the third game 'Do not pursue Lu Bu.', which became a bit of a meme. The achievement for beating him the first time he appears in number seven is 'Ok, you can pursue Lu Bu.'
During the ending of Earthbound, Ness' mother refers to Giygas using an incorrect name that bears resemblance to prototype names for Gyiyg/Giegue/Giygas for back when MOTHER was going to be officially released in English.
In the sequel Mother 3, if you look at a certain bookshelf you will find the Overcoming Shyness book from EarthBound. A shelf in the Chimera laboratory can be examined to find the "demon child" story from the run-down house in the same game.
Also in Mother 3, guess what one of Lucas's best weapons is? A baseball bat.
Aside all the Legend of Mana references in Sword of Mana there are twins in the town of Ish practicing summonings. One speaks "Klnka Irma Myron Tinqua" which are the words in the original Final Fantasy Adventure to reverse the Waterfall. The book the kid lost in Topple is about Magical Vacation which was another game produced by the developers. Finally in game there is the Brown Brownie which gives the Brownie Ring a staple item in game produced by Brownie Brown that is often dummied out.
In a reference doubling as a reference to Devil May Cry 3 and to itself, Vergil's opening line if Dante is the lead on the opposing team says "Sorry I'm late to the party", referencing the pre-boss banter from their first fight in DMC3, and to the fact that Vergil was not present in the original game, only being added in Ultimate Marvel vs. Capcom 3.
The Halo series is rife with references to other Bungie games and meta-elements. In the words of former Bungie public liaison Matt Soell, "Anyone can enjoy Halo, but it will be the old-school Bungie fans who enjoy it the most."
The Marathon logo is visible in many places, particularly in the first game, but most notably on the eye/lens of 343 Guilty Spark and the other Monitors.
The Covenant cruisers look just like the Pfhor ships from that series.
Any time an NPC in the game yells "They're everywhere!" or "Thank god it's you!" is a reference to the first Marathon'slimited NPC reactions.
Several mid-mission chapter names are also references to older Bungie games, such as "If I Had a Super Weapon..."
Visible in Halo 3 and Halo 3: ODST is the logo of the in-universe company Traxus Heavy Manufacturing, named for an AI in Marathon.
The Security armor variation is heavily based on the protagonist of Marathon, with the logo just above the visor for good measure.
Several of the mining facilities in Halo: Reach are owned by the BXR company, a reference to a well-known exploitable glitch in Halo 2 that involved pressing several controller buttons at once.
Wario is often seen using an Ultra Hand as a special attack because Nintendo engineer Gunpei Yokoi invented the device.
In Inazuma Eleven 3, several of the original Raimon team members from the first game get Put on a Bus early on by not getting picked for the Inazuma Japan team. Starting in Chapter 5, a team of four of the aforementioned characters become one of the mini-battle Random Encounters in Liocott Island's Japan Area. If they show up to challenge you, the ensuing battle will have a couple cosmetic elements revert to the first game's style, particularly the background music.
If you're a Japanese who's huge lover of classic Shoot Em Ups and Konami, you might claim Parodius to be actually the Smash Bros of Shoot Em Ups, with lots of Japanese craziness and LSD, and is also a huge tribute to Konami's Shoot Em Ups as well as its other famous game series. At first it was meant to parody Gradius, but as the series evolved on, characters like Goemon and Ebisumaru, Twinbee and Kid Dracula started to show up, each equipped with weapon sets taken from many Shoot Em Ups of the time. The inclusion of some bosses and villains from other Konami games and classic music medleys along with Konami's music (mainly from Gradius) doesn't help.
In the Geneforge series, servant minds are immobile creatures that act somewhat like organic Magitek computers. Since the first game takes place on an island abandoned for about two hundred years, you would frequently have to find preserved jars of nutrient paste and feed the minds for them to be able to interact with you coherently. In the fourth game you can find a cupboard full of jars of mind food, and the narration notes that
You consider taking one of them with you, but decide against it. What use could a self-respecting adventurer have for this stuff?
The boss of the Tutorial in Dark Souls is the Asylum Demon, which bears a more than passing resemblance to the Vanguard that ended the tutorial in Demon's Souls. In contrast to the Heads I Win, Tails You Lose near-Hopeless Boss Fight scenario of the Vanguard, after initially having to flee from the Asylum Demon, you come back with a proper weapon and a vantage point for a Dynamic Entry and utterly destroy it — this is hugely satisfying to anyone who played the earlier game.
The Peanuts iPhone/iPad game "Snoopy's Street Fair" has plenty of these, especially with regard to minor characters who have their own booths. Frieda has a cat-petting booth featuring her cat Faron (who disappeared after only a few strips), Emily (who met Charlie Brown at a dance studio) is selling dance supplies, Lydia (the girl who constantly changed her name) has a "Guess the Name" booth, and Shermy, who sold root beer in one of the early strips, is back in business.
Other minigames also contain references to past Kirby games and the anime such as Customer Service appearing on the game over screen of "Strato Patrol EOS", Macho-San/Max Flexer, and Chef Osaka/Shitake appearing in "Kirby Quest", and one of Kirby's attacks in the minigame being Kabuki Kirby from Kirby 3D. This is just the tip of the iceberg if you're a longtime Kirby fan
In the intro of Sim City 2000 you'll see a UFO flying into the centre of a spiral galaxy. Fast forward to Spore, where you explore a galaxy in the last stage. If you manage to navigate to the centre of that galaxy, you'll find...
In Baldur's Gate there are merchants selling items belonging to a lot of the companions of the Nameless One in Planescape: Torment, such as Vhailor's helm, Dakkon's zerth blade etc.
In Shadows of Amn, Imoen hints that their captor have taken and sold the party's gear. You will thoughout the game come across items you could potensionally have in Baldur's Gate.
The Team Fortress 2 short "Meet the Sniper" begins with Sniper poking a bobblehead in his van. Many people mistake the bobblehead for G-man, but it's actually Civilian from Team Fortress Classic, which had ten classes instead of nine.
The absence of the Civilian class is also referenced in-game. When playing on Harvest during the month of October, you will find a gravestone which reads "R.I.P. The tenth class".
Demoman wears an eyepatch and knit cap just like the TFC Demoman did.
The Engineer Update showed us that TFC Engineer is TF2 Engineer's father.
Team Fortress Comics #3 has (nearly) the entire TFC team form Team Gray, with the only missing member being the Medic, whom has been replaced by the Team Fortress 2 one. The TFC logo is even added to drive the point across.
In Resident Evil Gaiden, Barry Burton comments on the darkness in his boss's office, only to be told that the the closet the lightbulbs are in a closet locked by a missing crest. Several of the Resident Evil games involve searching for crests to unlock doors.
The 2010 remake of Splatterhouse features loads of nods to the original trilogy, and even a few to Splatterhouse: Wanpaku Graffiti. Some of the achievements are named for quotes from the original games, such as "Jen Smells of Rot... Of the Grave" and "Be the Garbage of Cesspool". The stage 2 boss, Golem, starts out as a Creepy Doll floating in a room full of telekinetically animated furniture, much like the poltergeist boss from the first game. The chainsaw-wielding That One Boss Biggy Man also makes a return as the boss of stage 4, and the Terror Mask's reaction is "Wait, wait, wait, I know this guy! ...Yeah, we are screwed."
One of the secrets linked to an achievement in Serious Sam 3: BFE is Sam's "classic outfit". Said classic outfit consists solely of the bright red Converse-like sneakers Sam wore in every other game.
In one of the first small scenes of DmC: Devil May Cry, an explosion causes a white wig to land on Dante's head, causing him to look like the Dante from the original series, upon which, after a pause, he says "Not in a million years" and shrugs the hairpiece off.
In the 2012 Twisted Metal game, the second boss will occasionally tell the player Mr. Grimm that when he's dead, she might use his skull for a helmet. This alludes to Twisted Metal: Black, where the incarnation of Mr. Grimm in that game was a Vietnam veteran who ate his dead squadmate and did the same thing with his skull.
His Hamon Crossbow special is the same weapon he used when fighting Wham. The H version of the move where he fires it backward and the ball whirls around the arena, hitting the opponent from behind, is the same trick he used against Wham.
His Hamon Cola special is the same move he used to punish a racist New York cop at the stat of Part 2.
He uses the Red Stone of Aja in his Hamon Beam super to amplify his Hamon ability and fire a really powerful, unblockable beam.
His "Master's Teachings" super flashes an image of Caesar Zeppeli if the first punch hits, complete with Joseph screaming "CAEEEEEEESAAAAAAAAR!!" and the rest of the super shows images from their training and other Part 2 moments.
Oddly, Polnareff has a super in JJBA onward where a Stand Arrow from Part 4 flies in, hits Silver Chariot, causing it to turn into its Requiem form from Part 5 and put the opponent to sleep. A Part 3 game with a super move that references to Parts 4 and 5. At least Polnareff's not in a wheelchair or a turtle this time.
The attract mode sequence also flashes manga panels from parts 1 and 2.
One of Dio and Shadow Dio's special moves is Space Ripper Stingy Eyes, the same Eye Beams he used to fatally wound Jonathan at the end of Part 1 (And used by Straights in Part 2)
When hit by Alessi's Stand, Old Joseph becomes Young Joseph. When Young Joseph is hit, he gets even younger and is reading a Superman comic, just how he was in a flashback in Part 2.
Nena (One of Dio's Stand assassins) cameos in one of Hol Horse's intros where he dismounts an elephant and bids her farewell. ("Jada, aishiteru ze."translation "Later. I love ya.")
Old Joseph says his signature "Your next words will be..." to Dio in his ending. And Dio walks right into it.
Sorcery Saga kicks off with the main character having to climb a magic tower and retrieve a magic orb as part of the final exam for her school, in a direct reference to the plot of the original Madou Monogatari.
Animal Crossing: New Leaf has several references to previous games in the series:
In the beginning, Rover mentions that he hasn't ridden the train since 2002—the release year of the original game.
When discussing your first down payment with Tom Nook, he mentions that it's easier to make money on your own than to get low-paying part-time work...like he gave you in the previous games.
Timmy and Tommy sometimes mention that their shop doesn't have a points system, referencing the shop in City Folk.
Gulliver mentions that he has a hard time convincing people that he's been to space. In Wild World and City Folk, he arrives in a spaceship instead of washing up on shore like the first game and New Leaf.
Pete says that he doesn't fly when delivering letters anymore because someone would shoot him down with a slingshot. That "someone" being the Player Character of City Folk.
Characters will talk about trains as a metaphor for the games, saying that the train is the fourth-generation versionnote New Leaf is the fourth game in the series, that it's completely different from the past two generationsnote the second and third games, Wild World and City Folk, were criticized for being Mission Pack Sequels; New Leaf makes several changes to the formula, and that it's "inherited" some of the "DNA" from the first generationnote New Leaf re-introduces some mechanics not seen since the first game, e.g., the train and island.
Might and Magic X is filled with references to pre-Ubisoft works in the franchise. Though the Receding Horizons and Jassad's Bestiarynote the reason why 'works' and not 'games' was used — the quest is a reference to the mid-90s novels quests might not count, as they imply that Ashan might be in the New World Computing verse, which would make those quests closer to Call Backs than this trope.
