History Main / AdaptationExpansion

* ''Iron Tank'', the NES adaptation of Creator/{{SNK}}'s ''TNK III'', was greatly expanded from its arcade counterpart, with branching paths, bosses, new enemies and weapons, and a BlindIdiotTranslation ("Watch out, use radar, gigantic enemy objects up ahead!"). In fact, most NES adaptations of arcade games did this, making up for the severe technical shortcomings of the time with additional content. Sometimes they ended up being completely different from their predecessors, and sometimes even [[AdaptationDisplacement surpassed the original]] in gamers' memories (''VideoGame/BionicCommando'', ''VideoGame/NinjaGaiden'', and ''VideoGame/{{Rygar}}'' being prime examples of the latter).

** ''AdaptationExpansion/FamilyGuyFanon''

* The UsefulNotes/SegaCD version of ''VisualNovel/{{Snatcher}}'' features an extended opening sequence that adapts the prologue comic from the manual, which depicts Gillian and Jaime's last conversation before Gillian begins his first night as a JUNKER agent. It also features an ending that reveals what happened to [[spoiler:Mika and Katrina before Gillian leaves to destroy the Snatchers' main base in Russia]].

* The UsefulNotes/PCEngine CD version of ''VideoGame/{{Raiden}}'', in addition to the obligatory Redbook music, had two additional levels with their own music pieces. Much later, the UsefulNotes/XBox360 port of ''VideoGame/{{Raiden}} IV'' also had two exclusive stages, somewhat alleviating the short length of the original arcade game.

* The UsefulNotes/SegaGenesis version of ''VideoGame/{{Wardner}}'', titled ''Wardner no Mori SPECIAL'' in Japan, expands Stage 4 and divides it in half, and lengthens the final stage with a BossRush and several vertical shafts.

* ''[[VideoGame/{{Frogger}} Frogger: The Great Quest]]'': The PC version has an entire new level set between "Dark Trail Ruins" and "Starkenstein's Castle", simply called "The Dark Trail", where you have a boss that was not in the UsefulNotes/PlayStation2 version.

* ''VideoGame/MarioKart8'' keeps the tradition of the series of bringing back tracks from previous games remade with newer graphics, but while previous games tried to recreate those retro tracks in every detail, ''Mario Kart 8'' takes many liberties and adds a lot of graphical details that weren't in the originals, and they also change the layouts and gameplay elements to acomodate for the new mechanics. But the tracks that had the most changes were the ones from the [[VideoGame/SuperMarioKart SNES]] and [[VideoGame/MarioKartSuperCircuit GBA]] games; those games were 2D, but used Mode 7 to simulate 3D at the cost of a completely flat terrain, so the remakes made the courses way different and ditched the flat terrains for more ups and downs. The tracks Cheese Land and Ribbon Road look almost nothing like the originals even if you compare them side to side. [[https://www.youtube.com/watch?v=8GRjzJVDLbM Here's a comparison of all tracks.]]

While this trope can be associated with the fan complaint "TheyChangedItNowItSucks!", it also can be done excellently. Remember that Administrivia/TropesAreTools and extensions for adaptations might need to happen to fill the required runtime, just going about it right is the problem most productions face.

* ''VideoGame/Rockman4MinusInfinity'' is a RomHack of ''VideoGame/MegaMan4''. It still has the same plot as the original, but the levels have been expanded, there are new minibosses and the powers obtained from the Masters have changed.

** The postgame dungeon, Thabes Labyrinth, ended up giving a full backstory to [[spoiler:Grima, the BigBad of ''[[VideoGame/FireEmblemAwakening Awakening]]'']], revealing [[spoiler:him and the Risen to have been created by the forbidden experiments of a "demon alchemist" named Forneus. In response, the Thabean Council sealed away Forneus and his creations in the confines of his workshop, and the player can confront a younger, weaker version of the Fell Dragon at the very bottom of the labyrinth]]. (This also implies Alm and Celica [[spoiler:may have inadvertently released Grima onto the world by removing the seal on Forneus' workshop]]. [[NiceJobBreakingItHero Whoops.]]) Thabes itself originally only had an offhand mention in ''[[VideoGame/FireEmblemMysteryOfTheEmblem Mystery of the Emblem]]'', described as an ancient civilization residing in the Mamorthod Desert.
* ''VideoGame/ReturnOfTheDarkSorcerer'' contains an optional extended intro that expands on the backstory of the mission to locate and seize the frozen esper during the prologue of the original ''VideoGame/FinalFantasyVI'' as well as additional pieces of dialogue in existing scenes to better flesh out some things that were LostInTranslation.

* TheMusical of ''Vanities'' added a DistantFinale where the characters reunite in their home town in TheEighties, remedying the rather [[NoEnding anticlimactic]] ([[DownerEnding and rather unhappy]]) ending of the original. Also, in the off-Broadway production, the story is told from a HowWeGotHere point of view, rather than directly following the girls through the ages.

** ''[[AdaptationExpansion/FamilyGuyFanon Family Guy Fanon]]''

* The manhua adaptation of ''VideoGame/TheKingOfFightersXII'', considering that it was based on a plotless DreamMatchGame that essentially served as an [[ObviousBeta beta release]] of ''VideoGame/TheKingOfFightersXIII'', thus had to make up a whole plot involving the cast getting caught in the crossfire between [[VideoGame/TheKingOfFightersXI Magaki]] and [[VideoGame/TheKingOfFighters2002 Nameless]], alongside throwing in several cameos from characters such as [[VideoGame/ArtOfFighting Kasumi Todoh]], [[VideoGame/TheKingOfFighters94 the American Sports Team]], and perhaps [[UnexpectedCharacter most surprisingly]], Wolfgang Krauser, Laurence Blood and Axel Hawk from ''VideoGame/FatalFury2''.

** One of the more prominent examples is a manga for ''[[VideoGame/SuperRobotWarsAlpha Super Robot Wars Alpha Gaiden]]'', which involves TimeTravel. The story showcases what happens during the timespan between the first game and ''Alpha Gaiden'' (which is only referred in one or two lines in the game), some background on the [[EnfantTerrible Machinery]] [[CloningBlues Children]], expansions on battles and what exactly happened to the cast from ''Alpha'' that is left behind by those who are transported to the BadFuture.
