Cult Classic

See Category:Cult Classic for the description that used to be here.

Anime and Manga

 * The medium as a whole everywhere except Japan (especially in North America).
 * Akira, a.k.a. THE definitive cult anime in the English-speaking world. Released in Japan to relatively little fanfare in 1988, it gradually began to pick up popularity in the US and UK during the 90s as the dubbed VHS tapes were circulated among schoolboys, students, sci-fi and animation fans, until by 2001 it was such an underground phenomenon that the US distributor reportedly spent over $1 million on a film restoration and new dub for its DVD release, and recent months have seen large portions of the Internet (even outside the anime fan community) in an uproar over a controversial proposed Hollywood adaptation. It is often credited with single-handedly creating the overseas market for adult-targeted anime and paving the way for other international hits like Ghost in the Shell.
 * Early Anime:
 * Astro Boy
 * Battle of the Planets
 * Speed Racer
 * Star Blazers
 * The works of Satoshi Kon
 * Perfect Blue
 * Millennium Actress
 * Paprika
 * Neon Genesis Evangelion (about as mainstream as anime can get in Japan, but a cult phenomenon in the West, even among anime fans)
 * Berserk Is very well known in the manga fandom for it's high quality, but it still defines this trope because of it's ultra violent, semi pornographic and all out grimdark nature that keeps it from ever becoming mainstream.
 * The Canadians and a fair amount of Americans love Spider Riders.
 * In the United States, practically every well-respected anime that aired on Adult Swim last decade has developed a cult following as a result. Many of these have eventually become mainstream, as have many of Toonami's (see below) anime programs.
 * Cowboy Bebop
 * Samurai Champloo
 * Trigun
 * Wolf's Rain
 * FLCL
 * Crayon Shin-chan
 * The Big O
 * Outlaw Star
 * Inuyasha
 * Ghost in the Shell: Stand Alone Complex
 * Eureka Seven
 * Lupin III
 * Paranoia Agent
 * Detective Conan (AKA Case Closed)
 * Blue Gender
 * Bleach
 * Code Geass
 * Death Note
 * Neon Genesis Evangelion, already a cult phenomenon since the 90s, experienced a resurgence in popularity after being aired on the network.
 * And the mother of all anime cults: Fullmetal Alchemist.
 * Before Adult Swim, there was Toonami, which (aside from mainstream hits like Dragon Ball and Naruto) also created a devoted cult following for the likes of:
 * Tenchi Muyo!
 * Mobile Suit Gundam
 * Yu Yu Hakusho
 * Rurouni Kenshin
 * The Ringing Bell Of Chirin (a dark film about a Chibi little lamb)
 * Excel Saga
 * |Ghost in The Shell (anime films)
 * Giant Robo
 * Ginga: Nagareboshi Gin and
 * Ginga Densetsu Weed'
 * Hyakko
 * Kurau Phantom Memory
 * Legend of the Galactic Heroes, a.k.a. "the greatest anime that will never leave Japan".
 * My-HiME
 * Guyver
 * Nekojiru Sou, being also Widget Series.
 * SD Gundam Force
 * Revolutionary Girl Utena
 * Utena's professed spiritual successor Star Driver is shaping up to be this as well.
 * Among American audiences, Teknoman (the English adaptation of Tekkaman Blade). Despite its questionable quality, fans loved it to the point that Tekkaman Blade II was frowned on despite staying more faithful to the source material.
 * Tengen Toppa Gurren Lagann
 * Wandering Son. Even despite the anime and its intentional reaction, it has changed little in popularity.
 * RahXephon
 * One Piece for America. After 4Kids' Cut and Paste Translation drew away most of its potential audience, Funimation's significantly more faithful dub has been working to gradually win them back. A rare case in that it's not as lesser known in most other countries (especially not Japan).
 * The Bowdlerized 4Kids dub itself is probably more of your standard Camp Classic since its compellingly awful quality makes for good entertainment. See the comparison.


 * Slayers was once very, very popular when it was released in America in the late 90's. Due to its fourth and fifth seasons being held off for an unGodly long time, the fanbase shrunk, and now it's more or less this trope, but fans old and new still love it.
 * Gunslinger Girl, a cult series even within anime fandom.
 * Baccano!
 * The Animatrix, an anime Adaptation Expansion of The Matrix series, is fairly little-known in most circles but has a devoted following of sci-fi and animation fans, many of whom consider it to be better than the film that inspired it (or at least its sequels).
 * Monster Rancher, an underrated gem among Mons series.
 * Anime movies as a whole tend to be this. Arashi no Yoru ni, 5 Centimeters Per Second, Tekkon Kinkreet, Akira..
 * Pokémon manga as a total, even Pokémon Special.
 * Afganisu-tan
 * Sailor Moon
 * Dash! Yonkuro! and Bakusou Kyoudai Let's and Go didn't get an exported to America, and they were forgotten after the shows ended, though there are still group of people in Europe and Asia who read/watch these anime and play their mini-4wds, which is what these series encouraged them to in the first place.
 * The Mysterious Cities of Gold was popular in France and the UK, but it has a cult following around the world, primarily in the US and Japan (the latter of which it was made in and bombed with audiences, preventing the creation of later seasons).
 * Wild Knights Gulkeeva
 * The Toei season of Yu-Gi-Oh!, erroneously referred to by fans as "Season/Series Zero."
 * Axis Powers Hetalia tends to be seen as this in certain parts of the world.
 * Some light novels later adapted to manga and anime, such as Gate and Shimoneta: A Boring World Where the Concept of Dirty Jokes Doesn't Exist have become this.
 * Legend of Galactic Heroes, both for the original novels and their myriad adaptations.

Tabletop Games
Many tabletop RPGs are a cult within a cult following, including;
 * Bunnies and Burrows
 * Call of Cthulhu
 * Deadlands
 * In Nomine
 * Pinball in general.
 * Traveller
 * Dungeons & Dragons has been the go-to RPG for decades, and has served as the Trope Codifier for most modern Fantasy and RPG games and media ever since.

Theatre

 * 13
 * Greater Tuna
 * Jesus Christ Superstar
 * Hair
 * Little Shop of Horrors (the off-Broadway production)
 * Despite Andrew Lloyd Webber's attempts to disown Starlight Express, the musical has attracted a small but extremely dedicated fanbase, many members of which dress up as the characters a la The Rocky Horror Picture Show, interact with the actors backstage, and travel to cities and overseas to attend as many productions as possible.
 * The Revels productions
 * Sweeney Todd: The Demon Barber of Fleet Street
 * Repo! The Genetic Opera
 * Rent You know. Rent-heads, and all.
 * Spring Awakening has a following who call themselves "The Guilty Ones".

Theme Parks

 * The Pirates of the Caribbean ride on which the film franchise is based is so cult, it attracted a fandom backlash before the movie was released over Johnny Depp and his gold teeth. The resulting kerfuffle only helped sell the film, of course.
 * Although it was closed after eight years of operation for scaring the pants off of too many little children, the Extraterrorestrial Alien Encounter at Walt Disney World has a loyal following who admire the attraction for its dark humor and rich atmosphere.
 * Mr. Toad's Wild Ride is a bit cult, to the point where Disney made a film based on the ride instead of the book (The Wind In The Willows). There are shrines to the attraction years after it closed down.
 * Disney's film The Wind in the Willows was based on...the book. It came out in 1949, while the ride (and Disneyland itself) are from six years later. The 1996 adaptation of Kenneth Grahame's book was then titled Mr. Toad's Wild Ride in the US, presumably so people would make a connection to the Disney ride.
 * The Great Movie Ride.
 * Drachen Fire was a steel roller coaster at Busch Gardens in Williamsburg, Virginia. The ride was infamous for being very rough and encountered many problems during its lifetime. It opened in 1992 and closed in 1998; the park attempted to re-open the coaster in 2002 but failed and ended up demolishing it. Despite the ride's many problems, it had/still has a cult following by coaster enthusiasts and fans of the park.

 * Fur Fighters

 * Revelations: The Demon Slayer
 * Most of the other old Shin Megami Tensei games would fall under this as well.
 * And most Atlus games in general.
 * Sky Gunner anyone?
 * Same applies to Princess Crown.
 * Or any other game made by Vanillaware.
 * Rise of the Triad
 * River City Ransom
 * Riviera: The Promised Land
 * Rocket Jockey
 * Terra Nova Strike Force Centauri
 * The Room the Game (not to be confused with Silent Hill 4 or those "trapped in a room" games)
 * Sam and Max Hit The Road (too soon to say for the Telltale games?)
 * Settlers
 * Shadow Hearts
 * Shadow of the Colossus
 * Shantae
 * Shin Megami Tensei series and spinoffs over here at least. In Japan it's up there with Final Fantasy and Dragon Quest.
 * Sid Meier's Alpha Centauri

 * Star Control
 * Star Control II
 * Star FOX
 * StarTropics
 * Starsiege: Tribes
 * And Starsiege itself is already Earthsiege in the future!
 * Steel Battalion
 * Strider (both the NES and arcade version, as well as Strider 2)
 * Osman, its Spiritual Successor, is on its way to attaining this status.
 * Suikoden II
 * Actually, comparing to other Eastern RPG series, the whole Suikoden series is pretty much a cult classic.
 * Syndicate
 * System Shock and especially its sequel.
 * Ogre Battle and Tactics Ogre
 * The Tale of Alltynex trilogy.
 * The Tales (series) has had a couple commercially successful installments in America, to varying extents, but the series overall outside Japan is very much a dedicated niche. Not helped by how many of the games don't leave Japan to begin with.
 * Tales of Symphonia
 * Tales of the Abyss
 * Tales of Vesperia
 * Tecmo Bowl (NES) and Tecmo Super Bowl
 * Thief
 * Time Splitters (It did sell pretty good, but it was never a huge hit. Nevertheless, it still has a very devoted fan base to this day.)

 * Tumblepop
 * Ultima (also a Long Runner)
 * An Untitled Story
 * Vagrant Story
 * Valkyria Chronicles
 * Valkyrie Profile
 * Viewtiful Joe
 * Wild ARMs
 * The World Ends With You
 * X-COM
 * Xenogears
 * Xenosaga
 * Xexex, obscure, but well loved by those who have played it.
 * XIII, the video game adaptation at least
 * Yume Nikki; a strange, little freeware game by un unheard of Japanese creator, too large to be browser-based, and only distributed by the fans. Yet it has created no less than two dozen fangames (all of which can be seen here), massive amounts of Wild Mass Guessing, and an incredible amount of Memetic Mutation. And the game's only been released as Version 0.1.
 * Zak McKracken and the Alien Mindbenders
 * Zone of the Enders
 * Zork
 * Interactive Fiction in general is a cult genre comparable to CB radio.
 * Same with Multi User Dungeons.
 * Anything by CAVE.
 * Anything by Clover Studios.
 * By proxy, the same could be said of most of Platinum Games' work.
 * Anything by Humongous Entertainment.
 * Anything by Nippon Ichi, though Disgaea is the company's most famous work.
 * Anything by Suda 51.
 * Anything by Treasure.
 * Anything by Vanillaware. Their ranks are comprised of the same former Atlus members that worked on the aforementioned Princess Crown (in fact, Odin Sphere and Muramasa: The Demon Blade are Spiritual Successors to Princess Crown).
 * Japanese Visual Novels in general, i.e, the good ones.
 * Then there are the cult classics among this already niche genre, namely Brass Restoration, Narcissu, True Remembrance...mostly doujin stuff.
 * Shmups in general, at least in modern gaming (back in the Golden Age, they enjoyed mainstream popularity).
 * Fighter's History
 * In the same vein, Visco's Breakers. Ironically, while Fighter's History was known as the SFII copycat (to the point that Capcom filled a lawsuit against them), it was Breakers that had a larger number of Captain Ersatzes on the roster. Regardless, both titles were good enough to receive sequels (Fighter's History Dynamite and Breakers Revenge) and possess dedicated followings despite having fallen into obscurity.
 * All of the titles made by Ukrainian developer Deep Shadows count.
 * Boiling Point: Road to Hell
 * White Gold: War in Paradise and
 * The Precursors (The last two only released in Eastern Europe, though fan translations are available)
 * The Great Giana Sisters and its DS remake.

 * ThunderCats

U-Z

 * Undergrads
 * Watership Down (US-only. It was quite popular in its native UK.)

Entire Media

 * Tokusatsu
 * Video Games used to fall under this, being seen as the exclusive domain of children and nerds. In the last decade, however, the success of products like the Nintendo Wii and iPhone App Store, as well as franchises like Halo, Grand Theft Auto, Madden NFL, Call of Duty and World of Warcraft, have made video games a much more commonplace and socially acceptable pastime. Still, most games apart from big-name franchises remain relatively obscure in mainstream popular culture.
 * Gamebooks have a small, but incredibly devoted following of readers, authors, bloggers, and programmers who kept the medium alive and thriving to this day.
