''Over the Edge'' is a tabletop roleplaying game by ''Jonathan Tweet,'' made in collaboration (to a certain extent) with Creator/RobinLaws and [[XtremeKoolLetterz Mark Rein·Hagen]]. [[note]] That's a large part of the team responsible for ''[[TabletopGame/VampireTheMasquerade Vampire: The Masqerade]]'' and ''TabletopGame/ArsMagica'', if those names mean nothing to you [[/note]]. If ''TabletopGame/UnknownArmies'' is the roleplaying game for the works of Creator/TimPowers and ''TabletopGame/{{Kult}}'' is the roleplaying game for the books of Creator/CliveBarker, then ''Over the Edge'' is the roleplaying game version of ''Literature/NakedLunch''. It also had a short-lived trading card game incarnation under the title ''On The Edge''.

The game is set on the mysterious Mediterranian island of Al Amarja, which is ruled by Monique D'Aubainne and various members of her extended family. The D'Aubainnes have most of the standard U.S. laws on the statute-books but basically only enforce them if you attempt to mess with the status quo, making Al Amarja effectively a Libertarian despotism. As a result, Al Amarja is home to every conspiracy imaginable (no, seriously, one splat-book has a table to determine [[spoiler:whether any given housecat is an alien and part of the huge Conspiracy of Cats]]) as well as a haven to all sorts of freaks and malcontents.

The native Al Amarjians ("'Marjians" or "Martians" in local slang) are a mongrel and polyglot population, much given to self-expression largely (but not exclusively) in the form of drinking, drugs, public weirdness and violence. And they wear nooses instead of neckties.

!! This roleplaying game provides examples of:

* AlienGeometries: The Terminal, Al Amarja's major airport. It's shaped like a step pyramid. An ''upside-down'' step pyramid. Try not to get lost.
* AllMythsAreTrue: At least, a good portion of them. And there's kitset rules for making up the rest of them.
* AncientConspiracy: Several.
* CityOfAdventure: The Edge, so much...
* CityOfSpies: [[spoiler:Pretty much every secret service has a branch on Al Amarja]].
* ConspiracyKitchenSink: [[spoiler:See above]].
* DoomsdayDevice
* ElvisLives
* EvenEvilHasStandards: Even other drug dealers think the Sandmen are freaks.
* [[EverythingsBetterWithMonkeys Everything's Worse With Baboons]]: The Dog Faces are a gang comprised of one old lady, her freaky radio technology and a ''horde of intelligent baboons''. They're dangerous, to say the least.
* EvilTwin: The Andalusia Dog's half brother, Rex.
* {{Expy}}: Al Amarja for [[Literature/NakedLunch Interzone]].
* FantasticDrug: Lots of them. And then subverted with Wings, which is ''sold'' as if it has the same weird psychic effects as the fringe-tech drugs, but is actually just LSD.
* GranolaGirl: The girls in Alpha Rho Tau.
* HighTimesFuture: Not only are drugs legal in Al Amarja, but there are some gloriously weird examples of Fantastic Drug too.
* {{Mad Scientist}}s : They're called "Oppenheimers".
* MilkmanConspiracy: These are also numerous.
* OmnicidalManiac: [[spoiler: Mr. [=LeThuy=], an unassuming Vietnamese man.]] He's also a dangerous nihilist who wants to destroy the universe.
* PuppeteerParasite: [[spoiler: The Kergillians]]
* RealityWarper: [[spoiler: The Cut-Ups Machine, and by extension the people in the Cut-Ups Project,]] will change reality if any organisation gets too close to running the world. The Throckmorton Machine is also a reality warper, only in the opposite direction and much more slow-acting.
* Really700YearsOld: according to one supplement, medieval alchemist Nicholas Flamel and his wife now reside on the island.
* SeriousBusiness: The Sommerites are a religion worshipping the rock vocalist Karla Sommers. They throw good parties.
* ShoutOut: Al Amarja is basically [[Literature/NakedLunch Interzone]] on even more drugs.
** One of the cards in ''On The Edge'' is The Centipede, a shout out to the film version of the ''Film/TheMask'' (which took place in 'Edge City').
** Assorted members of the Cut Ups are shout outs: [[Series/DoctorWho Doctor What]], [[Film/UnChienAndalou the Andalusia Dog]], Creator/TerryGilliam and real life rpg designer Doc Cross.
* ThoseWackyNazis: Monique D'Aubainne bought the island off them during UsefulNotes/WorldWarTwo.
* TomatoInTheMirror: [[spoiler: The glugs are the real humans. The rest of the human race are mutants bred to destroy them.]]
* ViceCity: The Edge.
* WretchedHive: Al Amarja.
