There is usually an OfficialCouple in most fiction: if you ship any other pairing than [[RanmaOneHalf Ranma and Akane]] or [[TheMatrix Neo and Trinity]], you are categorically rejecting the canon, and have proven yourself willing to DieForOurShip.

But there are some forms of NewMedia, especially DatingSims and {{Visual Novel}}s, where there's [[DisContinuity no real canon at all.]] While DatingSims sometimes have a TrueEnding that is canon, half of the time they don't, and so any and all pairings is equally canon - part of a quantum sea which only collapses into a relationship depending on the tastes of the observer. Tokho by Tayuka is no more and no less canon than Kei by Tayuka - there's no True Ending in ''ElvenRelations''. Neither is Keenan Caine as opposed to Josh Preston with Sara Smith - they're characters from a ''BlissStage'' one-shot that could go either way, or in a completely different direction!

When that happens, and when you ship your favorite pairings, you're on a TransDimensionalShip.

This still, of course, doesn't prevent a normally CrackPairing from being any less cracked.

* If this Troper remembers correctly, {{Clannad}}, the Visual Novel, is an interesting case in that it seems to deliberately invoke this trope as part of its central plot. Not only does it have the usual 'quantum sea' of the visual novel, as noted above, but each of the plotlines is [[spoiler:connected with a single, overarching story about a consciousness in the 'illusory world', and thus ''all'' of the possible outlines are 'canon'. Albeit only two get an After Story, though.]]
** However, the anime adaptation definitively sets [[spoiler:Nagisa]] as the canon love interest.
** Supported by the fact that the consciousness in the Illusionary world is [[spoiler:Tomoya and Nagisa's daughter, Ushio]]. The analysis on the game and anime's True End alone has lifted this series to MindScrew levels, complete with [[SeriousBusiness serious analysis]] on the internet, like say, [[http://tstorm.bwys.org/2009/03/clannad-after-story-17-22/ here]].
* ''FinalFantasyVII'' has a dating sequence with Aeris, Tifa, Yuffie or Barret depending on which character you treat the best. All of them reveal some characterisation detail to the point where it's impossible to choose just one to be canon (some people even argue that they're ''all'' canon).
* The ''HarvestMoon'' games have multiple pairing options, though there's usually a [[FirstGirlWins "default" spouse who's significantly easier to woo than the rest]]. (In something of a subversion, it's almost never the YamatoNadeshiko for guys.)
* Shipping in ''{{Persona 3}}'' is Trans-Dimensional by the nature of that game's DatingSim aspects, [[spoiler:although it could be argued that the True Ending is the one where [[TenchiSolution you go for everyone]] [[SpiritBomb and gain the ultimate Persona]] [[LevelUpAtIntimacy5 fueled by all of them,]] [[InfinityPlusOneSword Orpheus Telos.]]]]
** ''{{Persona 4}}'' uses the same system, though it also lets the player choose whether they want to pursue a more intimate relationship with a girl or just stay friends. (Not that the game ''bars'' you from two-timing...)
* Pick a DatingSim. Any DatingSim. ''[[FateStayNight fate/stay night]]'' and ''ElvenRelations'' immediately spring to mind.
* While ''TheSims'' 1 & 2 both start with some established couples, and 2 at least nudges the player in certain directions, it's possible to break up any relationship in favor of almost any other. The characters for ''The Sims 3'' are apparently a {{prequel}} of Pleasantview, probably a wise decision to forestall any "[[BigNo Nooo]]! Cassandra belongs with Don!" moments.
* ''[=~Star Ocean: The Second Story~=]/[[VideoGameRemake Second Evolution]]'' leans toward [[TheHero Claude]]/[[HealingHands Rena]], but allows the player to skew the RelationshipValues any way they wish, rewarding them with [[MultipleEndings different endings featuring their preferred couples]]. Or solo scenes, if they weren't particularly close to anyone else.

* The ''BlissStage'' one-shot has many characters in relationships [[HilarityEnsues set to explode.]] While [[TsundereLightning This Troper]] is partial to [[MoeCouplet Sara and Josh,]] the fact of the matter is that there can be no canon of a one-shot scenario meant to be played a million different ways.
