[[TabletopGames Tabletop RPG]] first produced by Game Designers' Workshop in 1984 set in the aftermath of World War Three (which took place in the late 1990s in that universe) and popular during the 1980s. Still played today, though- RPOL has a number of games in the setting.

The game centered around military characters, with the set-up in the first boxed set involving the last survivors of a US military division in Poland. The first few published adventures let the players journey through Poland and finally to the U.S., where they become involved with a conflict between the military and civilian governments of the shattered U.S. and the fanatical New America group. Supplements were also provided for playing in the Middle East or Britain. A popular trilogy of adventures also involved the last few nuclear submarines.

Suffered massively from TheGreatPoliticsMessUp, with the end of the UsefulNotes/ColdWar invalidating the time line. The second edition released in 1990 featured [[AlternateTimeline a new timeline]]. The new timeline didn't prove popular, especially in Germany, since whereas NATO launching a land invasion of Poland made some kind of sense when the latter was part of CommieLand, [[DoesThisRemindYouOfAnything the new timeline basically had Germany starting WWIII by invading Poland.]] This led some players to [[FanonDisContinuity disregard it]] and use the original timeline, treating the whole thing as an exercise in AlternateHistory.

A science-fiction RPG also from [=GDW=] and featuring many of the same writers and designers but not the same rules set advanced the first-edition timeline three hundred years and moved the action [[RecycledINSPACE into Earth-colonized space]]. Originally called ''Traveller: 2300'', the name was soon changed to ''TabletopGame/TwentyThreeHundredAD'' since it had nothing to do with any flavor of the ''TabletopGame/{{Traveller}}'' RPG. See that page for details.

The first scenarios were set in Poland, which [[CulturalCrossReference surprised some of the Polish roleplayers]], and they featured horribly mangled [[GratuitousForeignLanguage Gratuitous Polish]].

In addition to the main game, GDW released two alternative settings for the second edition of the rules:
* ''Merc 2000'', a game involving mercenaries (duh!) in another 2000 where the Twilight War didn't happen and a general global economic collapse leads to increased use of mercenary forces... the Germans and Poles still have a war, but it's a short one.
* ''Cadillacs and Dinosaurs'' set in the universe of ''ComicBook/XenozoicTales''

The second edition of the game also became [=GDW's=] in-house rules set, and was re-used with some modifications for the ''New Era'' edition of ''{{Traveller}}'' and the ''DarkConspiracy'' game.

A SpiritualSuccessor, ''Twilight 2013'' which featured yet another rules set and a very different timeline was released in late 2009 by 93 Games Studios, but they went out of business in 2010 with little more than the core rulebook having been released.

[[IThoughtThatWas Not be confused]] with ''Literature/{{Twilight}}'', with which it probably doesn't have a large crossover demographic. Though a crossover fic between the two would be [[CrowningMomentOfFunny hilarious]], confusing the two is one of the Blog/ThingsMrWelchIsNoLongerAllowedToDoInAnRPG.

!!Provides examples of:

* AcronymAndAbbreviationOverload: In keeping with the game's military tone, there are a lot of abbreviations used in the rules.
** Along with abbreviations for attributes, which is normal for a tabletop [=RPG=], all of the skills ''also'' have a two or three letter abbreviation.
** The vehicle damage location lists are full of abbreviations used in describing exactly what happens when it is shot at. So you get a dozen lines like R: LH(200),G(1000),HB(80) D,R,G,E,F for the M1 Abrams tank.
* AfterTheEnd: Kind of the point of the game, and played deadly straight.
* TheAllegedCar: There are at least ''four'' different elements that can turn any vehicle into one of those:
** The Wear Condition of a vehicle governs how badly damaged it is in ''general'' and how easily it can break down. Combat is the quickest way to increase the vehicle's wear condition, and of course characters in [=RPGs=] tend to get in a lot of combat. In combat each received hit can permanently increase the condition, turning a CoolCar into a piece of junk that requires constant maintenance in no time. When it has 10 breakdowns at Wear Condition 10, a vehicle becomes permanently useless except as scrap.
** The maintenance value determines how many hours per week must be spent on the vehicle to keep it in top condition. Combined with an unfavourable Wear Condition, it can turn any vehicle into CoolButInefficient.
** Fuel efficiency and type of fuel used. The most useful vehicles can run on alcohol, making them much easier to fill up. Others burn through their full tank in less than 200 kilometers.
** Transport capacity. It might not sound that important, but when you have to haul all your gear with you vehicles like tanks or small recon vehicles aren't exactly useful.
* AlternateTimeline: More recent versions of the game explicitly said that [[WorldWarThree the Twilight War]] and the events leading up to it are this.
* AntiAir: Aircraft became very scarce after 1998 or so, when most of the world's refineries were destroyed and aviation fuel became scarce. Anti-air units that were still functional have almost all been re-purposed as AntiInfantry units as a result.
* AntiArmor: By 2000, anti-armor missiles are more common than the tanks they were made to target.
* ArmyOfThievesAndWhores: By the end of the war, most armies were taking anyone they could draft, even conscripting locals. Many regular military units have also turned to banditry and pillage in Europe, becoming this.
* AsskickingEqualsAuthority: Military Experience and Time In Combat translate to the military rank a character has at the game's start. The way the character generation rules are structured, however, also means that characters with low combat experience have higher attributes and vice versa.
* BadassBookworm:
** Having a high Education can make a character into an NCO or even an officer by default, which will greatly influence their gear budget. It is also provides additional points for non-combat skills, and those are essential for survival, even more so than combat prowness.
** Being a member of the Support Services is probably the most valuable speciality any character can have, as they purchase mechanical skills for half price.
* {{BFG}}: It's entirely possible to start the game with a towed or even self-propelled artillery piece. As long as it has shells the party can easily blow through most opposition.
* BlindIdiotTranslation: The quality of the small bits of Polish included in the scenarios is just plain horrible.
* BoringButPractical:
** Preventive maintaince. Having a semi-competent mechanic with a well-stocked toolbox in the group is more essential than having a few highly trained Rangers and a doctor. Unless characters want to fight with just knives, maintaince is what they will be busy doing most of the time, both during play and in the meantime.
** Hand grenades and by extension, grenade launchers of all types and kinds. Fortified position? Cluster of enemies? Lightly-armoured vehicle carrying some {{BFG}}? Throw a grenade. Even if it won't kill or destroy everything, everyone in the realistically large radius of explosion will at least be in shock.
* CheeseEatingSurrenderMonkeys: Invoked and defied. France balked out from NATO and declared full neutrality [[KnowWhenToFoldEm before things went really bad]], but this is portrayed as a ''good thing'', since the country is left almost unharmed after the [[WorldWarIII Twilight War]], while everyone else is left in ruins. By TabletopGame/TwentyThreeHundredAD, France is the leading power in the world, precisely because they didn't have to rebuild after the war.
* ChunkySalsaRule: Any critical hit to the head is instant death; in the first edition getting damage more than four times your hit capacity to the chest and abdomen also counts (in the second, it's death within 10 minutes unless the bleeding is stopped).
* CommonTongue: In the European scenarios Russian is by far the most useful language. It's far from being "common" in the traditional sense, but most of people from the Eastern Block countries will know enough of it to communicate.
* CoolButInefficient: High Maintaince value combined with bad fuel efficiency can render even the best combat vehicle useless for the basic purpose of traveling.
* CripplingOverspecialization: The game subverts ElitesAreMoreGlamorous, since all sorts of elite soldiers are really good at fighting... ''and nothing else''. Unless the group contains a field medic, a mechanic and a [[TheScrounger scrounger]], the party can forget about making it through even the introductory adventure. The trope also applies to vehicles, as those best suited for heavy combat are just as badly suited for anything else, including moving between places.
* DespairEventHorizon: The game starts its players right next to the horizon, and it's up to them to find a way to avoid crossing it.
* DividedStatesOfAmerica: The prewar United States government has actually split into 'Civgov' (the old civilian federal government apparatus, led by Congress, the Supreme Court, and the President) and 'Milgov' (the United States military ruling its territory as a totalitarian dictatorship, led by the Joint Chiefs of Staff). Confusingly, Civgov has its own military consisting of units which have defected from Milgov and units mustered after the end of the war, meaning that for the duration of the setting there are actually two Armies, two Navies, etc. Taken together, the two control about a quarter of the old United States, with the rest ruled by a wide variety of different tribal warlords, local powers, foreign invaders, and the neo-Nazi 'New America' movement.
* EarlyGameHell: ZigZagged. Starting with a new squad is probably the easiest part, since charactrs are healthy, without any wounds, and well-rested. Most importantly their first aid kits and all of their initial weapons and vehicles start with full ammunition and gas tanks. This initial bonanza usually lasts for less than two full scenarios, after which ScavengerHunt becomes the norm.
* FallenStatesOfAmerica: Several of the sourcebooks, written as historical texts on past events, reveal that this is what eventually happens to the United States after the time in which the setting takes place. The nuclear autumn combined with the ongoing civil war results in a nation that doesn't have enough arable cropland to feed its population, in addition to all the other problems that come with the apocalypse. The different factions are eventually forced to call off the civil war and peacefully reintegrate in a desperate effort to save what little remains of the country.
* GreaseMonkey: With TheScrounger they make the essential duo for the survival of entire group. Every edition of the game makes it crystal clear that not having such a character in the party is simply suicidal.
* GreatOffscreenWar: WorldWarIII is actually pretty much over in 2000 when the first adventure is set, with the players as survivors of one of the last major battles. Everybody lost.
* TheGreatPoliticsMessUp: A major impact on the game, forcing the major timeline revisions between editions. It also impacted ''Merc 2000'', released as TheGulfWar was going on.
** Interestingly, stuff predicted by the timelines included Germany reunifying (first edition has it as the trigger for the war), the split of Czechoslovakia (''Merc 2000'', although it involves a civil war) and Kosovo's independence.
* HopelessWar: Nothing has really been solved by the war. The setting is more about survival and going home than accomplishing any of the war's original objectives.
* IWillFightSomeMoreForever: The [[TheEndOfTheWorldAsWeKnowIt destruction of civilization]] happens pretty much because the world's militaries [[KnowWhenToFoldEm didn't know how to stop fighting]], and they kept throwing good resources after bad until there was nothing left to fight with and the infrastructure that kept civilization going had been destroyed.
* {{Irony}}: The game by default starts in Poland, right next to Kalisz. Twilight 2000 never had a Polish translation or any publication at all in Poland. It is virtually unknown there outside a literal handful of players.
* LanguageBarrier: Intentionally imposed as one of the core rules, to strengthen the feel of isolation. Anything other than your native language costs skill points to buy. And using points to learn some foreign language to useful extent is not only costly, but also means said points weren't spent on ''other'', usually much more vital skills.
* LifeWillKillYou: Neglect food quality and variety or ignore things like oncoming winter and it will kill you. It's easier and more common to die from natural causes - and trivial ones to boot - than in actual combat. Also, staying around irradiated areas is a ''really'' bad idea, even if the party carries NBC suits.
* LoweredRecruitingStandards: By 1998 the U.S. Army in Europe was taking anyone they could get, even recruiting deserters from the other side and locals.
* MexicoCalledTheyWantTexasBack: Mexico invaded the US in 1998, with the help of the Soviet "Division Cuba", nominally to protect refuges that had fled from Mexico in prior years. As ''TabletopGame/TwentyThreeHundredAD'' shows, some parts of the former US remained in Mexican control for at least the next 300 years, though not Texas itself.
* MilitaryCoup: The heads of the military in the US refused to recognize the civilian government that was elected in the aftermath of nuclear strikes on Washington, so they effectively headed a coup.
* MilitaryScienceFiction: when it was produced it was of the TwentyMinutesIntoTheFuture variety, with only a few extrapolations in military hardware from the then-present, like an M1 tank variant with an un-manned turret.
* {{Minimalism}}: Not counting the cover art, all three editions were printed in a style echoing military guides. Internal illustrations are a "pencil sketch" style that might have been made by the characters.
* ModernBattlefieldWeapons: Modern at the time, anyway. Some of the slightly more futuristic stuff, like the German army issuing the G11 as a standard weapon, never happened in reality.
* NoBikesInTheApocalypse: Averted. Bicycles are considered much better than walking on foot. They by default multiply daily travel range by four, their maintaince is close to non-existent, and they don't require fuel other than eating roughtly 200 calories more per day of travel. They are also obviously unsuitable for combat and - depending on the edition - don't increase transport capacity or affect it only by a marginal value. With proper engineering and enough parts, it's possible to assemble a bike-powered cart, but again, it's only good for travelling and light transportation.
* NervesOfSteel: Coolness Under Fire is probably the most important factor for characters in combat. It determines a character's susceptibility to hesitation and panic. It doesn't matter how good you are at shooting if you can't keep your head clear and stay focused. Team weapons allow you to use the highest value of all people operating the gun, while having a co-driver with higher CUF provides the driver with a hefty bonus.
* OldSoldier: Military rank and combat experience are directly related with time the character already spent in combat before the game start. Age is a factor in this calculation, making soldiers in their early 40s best suited for actual combat. They make great non-combat specialists in their late 40s[=/=] or early 50s. [[RealityEnsues Just remember their age will affect their stamina too]].
* RagtagBunchOfMisfits: What any player group in this game is. By the year 2000 US Army units included lots and lots of personnel who were hardly regular army: other NATO military personnel from defunct units, deserters from the other side, and even local recruits. The 1st edition rulebook recommends that at least half of the group be American.
* ResourcesManagementGameplay: One of the core elements of the game is constant care for starting resources and the search for replacement parts, fuel, and ammunition, with half of all the rules dedicated to this. The game can turn lethal within single scenario if players aren't careful about their resources.
* RockBeatsLaser: {{Molotov Cocktail}}s are the bane of anyone using an armored vehicle. They don't kill the vehicle immediately, but If you ignore a hit by one your vehicle is on fire and will suffer increased Wear Condition or can even eventually be destroyed completely, killing the crew. If you get out to put the fire out you will probably end up killed by a waiting sniper or enemy crossfire... and the vehicle will still be burning.
* ScavengerWorld: With the nuking of most major cities and [[ThePlague the plagues]] and starvation that followed, the world has become this.
* ScavengerHunt: This is what characters will be doing for most of their spare time, or what's left of it after performing maintaince.
* TheScrounger: Having those in the party makes a difference between relatively easy passage to West German harbours and quick but agonizing death. Your party is as good as the guy(s) responsible for gathering supplies.
* ShoutOut: A subtle one in the 'Boomer' adventure. The Soviet Typhoon-class submarine 'Barrikada' is stuck in the polar ice pack. In the mission briefing, it's mentioned that the Barrikada is named after one of two famous factory complexes in Stalingrad. The other? [[Literature/TheHuntForRedOctober Red October]].
** The name of the supplement detailing the situation at New York City (which is overrun with criminal gangs)? ''[[Film/TheWarriors "Armies Of The Night"]].''
* ShownTheirWork: The first edition was clearly made by people who knew not only a lot about army operations and military gear, but also the then-recent political situation and cultural quirks, with meticulous details put into everything. And while the quality of the Polish is just cringe-worthy, the game had ''extremely'' detailed tactical maps of different parts of Poland, even including the layout of real streets.
* TankGoodness: "Lucky" player groups could start out with a main battle tank, but it's usually more trouble than it's worth, since fuel and munitions for it are extremely scarce. That makes them AwesomeButImpractical.
* TooAwesomeToUse: If a starting vehicle is something used by NATO with a gun mounted on it, getting new ammunition will be close to impossible. Meaning the 20-30 shells in it are all that the party will ever have. If the party is really unlucky, they might start with some recon vehicle carrying less than 10 rounds.
* TrappedBehindEnemyLines: The introductory adventure features this for the players.
* UrbanWarfare: This happens quite often in the game, though the biggest cities are usually radioactive craters.
* VehicularTurnabout: With working vehicles as rare as they are in 2000 this happens all the time.
* ViciousCycle: Depending on your group's starting vehicle and its condition, the game can quickly evolve into a loop of the same events: the vehicle needs a specific part to be replaced, the characters eventually end up fighting for it, in the process another part of the vehicle gets damaged and will require new spare parts soon or the characters will have to walk and abandon most of their gear. It's common enough to reach the status of MemeticMutation.
* WarIsHell: Amen.
* AWorldHalfFull: Countries who didn't participate in the war were left relatively unharmed. For example, while most of central and eastern Europe is an irradiated wasteland full of marauders that will kill you for a tube of toothpaste, France has martial law imposed and its untouched military guards the borders, but life continues much as ever.
* WorldWarIII: A limited nuclear exchange with a lot of conventional ground fighting mixed in.
* ZeppelinsFromAnotherWorld: One published adventure ("''Airlords Of The Ozarks''") pits the Player Characters against a neo-fascist warlord that has managed to obtain [[CoolAirship several commercial zeppelins]] (plus the means to create more) and plans to use them to provide air support to his growing army as [[ExactlyWhatItSaysOnTheTin they take over the Ozarks]].
