''Digimon World'' is a ''Franchise/{{Digimon}}'' videogame for the Playstation. Released by Bandai in 1999, as a result it is based more on the Digimon Virtual Pets rather than the better-known [[Anime/DigimonAdventure anime series]].

The main character is pulled through his V Pet device into the Digital World and is then tasked by Jijimon to rescue File Island from the corruption they have encountered. The majority of the Digimon have become wild and the only city has fallen into disarray.

The majority of the game revolves around the player raising their Digimon, much like the Virtual Pets. The Digimon the player raises is also forced to fight most of the other wild Digimon in order to try and return them to the city. This leads to some massive GuideDangIt moments, or even Unwinnable situations.

Critical reception was mixed and sales weren't strong, but the game has turned into somewhat of a CultClassic. It was followed by [[DigimonWorld2 a variety]] [[DigimonWorld3 of different]] [[DigimonWorld4 sequels]], as well as a card battle spin-off. [[DigimonWorldReDigitize A sequel also came out, this one closer to the original gameplay.]]
----
!!This game has examples of the following tropes:

* HundredPercentCompletion: Hoo boy. Getting all the medals in the game is the closest it has to HundredPercentCompletion, and to get every last one of them, you have to: beat the final boss, win every single one of the arena cups at least once, play for 10 in-game years, collect all of the cards, recruit all the recruitable Digimon, [[FishingMinigame catch one hundred fish]], raise ''every single obtainable Digimon'' and [[ArsonMurderAndJaywalking get a perfect score of 10]] [[ThatOneSideQuest in curling]].
* AffablyEvil: Some of the random {{Mook}} Digimon you run into can seem like this. One [=RedVegiemon=] casually asks you "Where you from, homie?" before battling your partner to the [[NeverSayDie dea- er, "fading away".]]
* AllInARow: Partner Digimon generally follow you.
* AwesomeButImpractical: A couple of powerful finishers.
** One of them is Giromon's. It's supposedly the most powerful in the game, but the way it functions prevents it from being useful a lot of the time. Unlike most finishers, which are guaranteed to hit the enemy when successfully launched, Giromon creates and throws a bomb into the ground, and the enemy has to run into the bomb to take damage. However, due to battle mechanics, you have no control over the direction Giromon aims. Combined with the fixed range of the throw, in smaller areas Giromon is likely to throw into the scenery (or even off-screen) where the enemy can't even reach.
** Another example and candidate for strongest finisher is Digitamamon's finisher, Nightmare Syndrome. It creates a ghost that inflicts damage by contact. The problem is that it flies randomly, so it either runs out of power, hits the enemy, or hits ''your own Digimon''.
** Powerful techniques in general. Many of them take several seconds to charge, which is plenty enough time for the enemy to attack, interrupting the technique. The fact that your Digimon's MP is drained as soon as the attacking animation starts could mean that your Digimon may be out of MP ''before it has hit the enemy once''. Of course, [[WhosLaughingNow there's nothing keeping you from using this tactic against the opponent...]]
* AwesomeYetPractical: Giromon is a hilarious SlasherSmile-sporting Digimon based on a naval mine carrying a chainsaw. He is also one of the easier ultimates to obtain, with pretty low stat requirements, and the freedom to make a lot of care mistakes (in fact one of the requirements to get one is making quite a few of them). He gets access to some of the best moves in the game, including All-Range Beam, Full Potential, and Thunder Justice. The only downside is his unreliable finisher.
* BadExportForYou: Almost every PAL version of the game has a bug that prevents you from entering a dungeon in the desert, in turn blocking you from recruiting Whamon and Shellmon. This makes the game hard to win since, without Whamon (who takes you to several new areas ripe with quests and recruitable Digimon) and Shellmon (whose Bulletin Board is needed to provide updates on some quests), you miss many champion and ultimate-level Digimon. Since the final dungeon is unlocked after you gain a certain number of "points" (earned by recruiting Digimon; the higher their level, the more points you gain), you have to scrap to unlock it.
* BackTracking
* BalefulPolymorph: The Flat status affliction causes a Digimon to revert to a two-dimensional appearance reminiscent of the old Digimon virtual pets. Until they change back, they are limited to a weak attack and cannot block, though they're invincible during the change animation.
** There are some undesirable digivolutions at Champion-level. They have lower stats than their previous forms, and occur when your Rookie doesn't meet the requirements for any other Champion (Numemon), has both its happiness and discipline reach zero (Nanimon), or poops a 16th time outside of a toilet (Sukamon, and this evolution happens the 16th time your Digimon poops out of a toilet regardless of its evolutive stage). When you get a Sukamon, the King of Sukamon at Trash Mountain will change it back, though. Funnily, the other Sukamon there seem to consider ''this'' a BalefulPolymorph.
* BecomingTheCostume: This is what happens if you have a Numemon and take it to the stuffed Monzaemon toy in Toy Town. The transformation has no negative effects on your Digimon, though, in fact it turns a ([[LethalJokeCharacter usually]]) useless monster into a potential DiscOneNuke. It's virtually the only time when the game will give you an Ultimate level Digimon as a Partner for free.
* BigEater: Many Digimon, such as Numemon and Tyrannomon, tend to demand large amounts of food to stay happy. Because of this, beginners and even veterans might find it difficult to support these two in the early stages of the game, having to spend a good amount of time looking for food and training their Digimon.
* BizarreTasteInFood: You know those piles of poop that your Digimon leaves behind if you fail to take him to the bathroom in time? They make [[SarcasmMode nice]] little (or not so little) [[{{Squick}} snacks]] for Numemon and Sukamon.
* BonusDungeon: Back Dimension.
* BrainwashedAndCrazy: Many of the bosses.
* BrokenBridge: Quite literally.
* CarnivoreConfusion: Digimon, regardless of species, do not eat each other. They do eat meat, but it's grown on a farm. Literally, it grows out of the ground like a plant. Even more confusingly, the farmers growing the meat are all sentient plants.
* CherryTapping: A few moves are fast, deal little damage, and consume little MP. Spamming these is actually a viable strategy, as the attack speed will interrupt almost every attack the opponent tries to throw your way and you won't lose a lot of MP.
* ConvenientQuesting
* CosmeticAward: The medals.
* CoversAlwaysLie: The PAL cover features the main Digimon roster from Digimon Adventure, ignoring the fact that Tentomon is just a common enemy, and Gomamon is ''completely absent from the game''.
* CurbStompBattle: Given that the only indicator of a Digimon's power is where they are or what level they are at, ones like Piximon tend to tear Rookie and Champion Digimon apart if you aren't aware of what they're capable of.
* DarkIsNotEvil: Most Virus type Digimon, or Digimon that were evil in the TV show, are perfectly sociable as long as they're not BrainwashedAndCrazy. The biggest example is probably Myotismon, who loves to entertain his guests, has a rockstar-like reputation and is a bit of a ReluctantMadScientist. Then, of course, there's your partner, which can take on all kinds of demonic or monstrous shapes but will be your loyal bodyguard at all times.
* DefeatMeansFriendship: Many of the Digimon you can recruit need to be fought first. Afterwards, they'll magically regain their memories and agree to join the city.
* DialogueTree
* DigitalAvatar: ''Everything'' is digital.
* DisappearedDad: It is never informed whether or not the protagonist has a father, only his mother who writes the letter at the beginning and is seen after beating Machinedramon is present in the game.
* DiscountCard: You get a 10% discount from the city's shop if your Digimon is Fresh or In-Training.
* DoesThisRemindYouOfAnything: The Happymushroom increases your Digimon's happiness, but may make him sick. [[MushroomSamba Wonder what kind]] [[GRatedDrug of mushrooms they are.]]
* DummiedOut: Numerous Digimon which didn't make the final cut can be accessed with a device such as Action Replay, many of them fully playable.
* DynamicLoading: Every time you switch to a new area.
* ElementalPowers: Most of the techs.
** PlayingWithFire: Fire techs.
** BareFistedMonk: Battle techs, with a RockSteady tech thrown in for good measure.
** ShockAndAwe and BlowYouAway: Air techs
** [[PoisonousPerson Poisonous Digimon]], BigCreepyCrawlies, and GreenThumb: Nature techs.
** MakingASplash and [[AnIcePerson An Ice Digimon]]: Ice techs
** ExtraOreDinary and FrickingLaserBeams: Mech techs.
** ToiletHumor: Filth techs.
* EndlessGame: Probably. The 10 year Glitch sometimes makes the game unable to reload a saved game after the 10th year of gameplay.
* {{Engrish}}: One of the arena cups is described as the 'Metaric Cup'. While a quick glance might give the idea that it's simply a misspelt version of 'metric', some fans think it's an Engrish translation of 'metallic'. Bizarrely, either of them could be the correct translation, as the cup is for cyborg Digimon.
** And some of the attacks, too, like "Metal Sprinter/Splinter" which throws small computer pieces around the screen.
** For whatever reason, [[http://www.spriters-resource.com/playstation/digimonworld/sheet/32147/ the intro screens]] for the different cups were left untouched in the international versions. The result is {{Engrish}} in spades, including such gems as "WHO's A MOST COOLER ?", "COME TUGETHER !!" and " [[GettingCrapPastTheRadar "CRAPPER's" CUP]]".
* EventFlag: This can lead to some almost {{Unwinnable}} moments.
* ExtremeOmnivore: Using items on your Digimon partner is represented as it eating said item. This includes floppies, evolution items, and even the [[{{Squick}} portable potty]].
* FishingMinigame: It will make you want to gouge your eyes out with boredom, and is full of GuideDangIt moments. The rewards are worth it, though...
* FriendlyNeighbourhoodVampires: Myotismon looks like a blond Bela Lugosi-style {{Dracula}}, owns a spooky mansion with coffins as furniture and a lab, and likes discussing matters over food. Also a really nice guy.
* GameBreakingBug: Oh so many in the US version. While most of them aren't ''quite'' at the level of "game-breaking", the game is absolutely [[IncrediblyLamePun crawling]] with bugs. The most commonly cited in that version is the jukebox bug, which ''crashes your game'' if you try to play it.
** Some [=NPCs=] (especially the ones in the [[BonusDungeon bonus areas]] in end of the game) will trap you in endless loops of dialogue that you can only leave by holding your left control away from the monster and rapidly pressing X to try to skip through the dialogue. If you're trapped in a corner and can't get past then your only hope is to reset.
* GameplayAndStorySegregation: The game addresses the fact that certain Digimon are simply too big to be partner Digimon. The non-battle NPC versions of these Digimon are full-sized, while the partner and battle character versions are smaller.
* GetOnTheBoat: Or rather, Get On The Whamon...
* GlobalAirship: Birdramon's movement service.
** Important to note that it is a OneWayTrip, where you'll need to walk back or use an Auto Pilot.
* GoldfishPoopGang: Ogremon's team.
* GoneHorriblyWrong: Myotismon's experiments result in a Skull Greymon who ends up [[TurnedAgainstTheirMasters taking his creator captive]]. The skeleton dragon [[DefeatMeansFriendship mellows out a bit]] after you defeat him, though.
* GratuitousJapanese: Basically, nothing but the text was translated - every occurrence of Japanese in the graphics are left as is. This is particularly confusing when Ogremon's gang takes over Drill Tunnel, as the player character reacts angrily when he notices that the sign on which the tunnel's name reads has been altered. The problem is that the sign is just a part of the background graphics, entirely in katakana and no translation is given for what is says when Ogremon takes over, potentially leaving quite a few Western players slightly confused.
** Speaking of the player character, his few voiced lines during actual gameplay are also left undubbed, resulting in him shouting "Yatta!" after winning a battle and saying "Oyasumi" when letting his Digimon sleep even in the international versions.
* GratuitousSpanish: Some Muchomon, in their pre-battle quotes.
* GravityBarrier: Partially averted in that you have to fall to get into a certain area of the game.
* GuideDangIt: On more than one occasion and certainly in regards to attempting to get ''that'' particular monster or opponent.
** Recruiting certain monsters can be this too.
* HauntedHouse: Grey Lord's Mansion, which has spooky music music and Digimon like Bakemon hanging around it, complete with a graveyard in front of it. It is owned by Myotismon. [[spoiler: It also houses Skullgreymon, Myostismon's creation.]]
** And Grey Lord's Mansion looks suspiciously like an expy of the mansion from ResidentEvil1.
* HeelFaceTurn: It is hinted that [[spoiler: Digitamamon]] is either the son or Digitama of Machinedramon himself, hence why he is so powerful. Despite this, however, he isn't evil, and instead decides to work at the City's Restaurant.
* HitPoints
* HoistByHisOwnPetard: [[spoiler: Analogman 'dies' as a result of his own weapon]].
* HotBlooded: Our nameless hero does not have many lines, but he challenges enough powerful Digimon to a fight and rushes into so many dangerous situations that we can safely assume he sits comfortably among the other Digimon protagonists. Sometimes the game gives you the option te be more prudent, but [[StupidityIsTheOnlyOption this is usually the inferior choice]].
* HumansAreBastards: [[spoiler:There's a whole archive worth of Digimon literature relating to this]].
** [[spoiler: Not to mention the BigBad is a human and pretty much a predeccesor to [[Anime/DigimonSavers Akihiro Kurata.]]]].
* InevitableTournament: Although there are battle arenas, they're not required to recruit Digimon. Non-combat tournaments are.
* Instant180DegreeTurn
* InUniverseGameClock: Lampshaded in-game.
* ItsUpToYou
* {{Jerkass}}: The Weedmon from [[ThatOneSideQuest Monochromon's shop minigame]] are the stuff of customer service nightmares. They usually ask for meat, the cheapest thing you can sell, can ''still'' call the price too high and ask for a discount and if you fail to meet their demands, they storm out. It's a wonder Monochromon hasn't banned the things from his store yet.
* LaserGuidedAmnesia: Many of the Digimon forgot their life in the city after they left. Some even forgot how to speak.
* LimitBreak: All the "Finisher" attacks.
* LuckBasedMission: In order to recruit Monochromon, you must make about 3065 BITS worth of profit working in his shop. Failure to do so essentially results in 8 digi-hours wasted (although, you do get paid a small wage for your troubles). There is nothing you can do but hope that the customer Digimon accept higher and universally standard prices without storming out, that they ask for Medicine and don't ask for meat, and that they are not [[PrecisionFStrike goddamn]] [[{{Jerkass}} Weedmon]].
** It's not a bad idea to Sleep/Save outside of the shop so that you can reload and try again if the game decides to be a dick. Naturally, you can do this as often as you like. Naturally, it quickly becomes tedious and annoying. Not having proper control over just how high or low prices can be set doesn't help. Save states are IMMENSELY helpful, here.
* KamehameHadoken: When a humanoid Digimon, such as Meramon, fires a Prominence Beam, it looks like this.
* MegatonPunch: The second strongest Battle technique in the game.
* MindScrew: The true ending if you go through the Back Dimension. [[spoiler:It's explained in the spin-off, ''Digital Card Battle'']].
* MirrorMatch: Possible but rare; you can fight a recruitable version of your Digimon.
** Especially common with the first boss, who is an Agumon, which is one of the two starter digimon.
* MoneyForNothing: One of the Yeti-like Mojyamon in Freezeland will trade your relatively cheap recovery items and easy-to-catch fish for hugely valuable stat boosting items. These can be sold for a lot more money than the previous items cost.
* NeverSayDie: Digimon are said to 'fade away' if they're slain, although this is justified as they don't die, but rather regenerate into a weaker Digimon.
* NoCartoonFish: One of the main sources of food.
* ObstructiveForeground
* OneBulletAtATime: Only one projectile per Digimon is allowed onscreen. For example, a Digimon can't use [[ScratchDamage Spit Fire]] again until after the first one disappears.
* OpeningTheSandbox
* PaletteSwap: Many of the 'NPC' versions of playable Digimon are slightly different colors to the playable characters (the "best" example being Betamon to [=ModokiBetamon=]; the latter's colors are just a lighter, more saturated version of the former). The toy versions of Agumon come in two variants - they're not palette-swapped, but one is ''partly transparent''.
** These palette swaps actually became official Digimon, appearing in later video games, the trading card game and even in the anime.
* PintsizedPowerhouse: Piximon, Mamemon, and Metalmamemon definitely qualify. All of them are really small, but they are all Ultimates. They're also pretty tough to recruit, having to go back and forth on screens until you finally see them, and then attempting to take them on.
** Giromon is also small, but is different in the others in that he doesn't randomly appear. Despite this, he's an incredibly powerful boss, having access to DG Dimension and an ultimate that is one of the most powerful in the game, albeit hard to aim.
* PokemonSpeak: The recruitable Bakemon in Overdell Cemetery can only say slight variations of "Bake". Since you need to answer a few yes/no questions to get him to the city, you need a Bakemon of your own who will [[TranslatorBuddy translate the former's speech]]. Or you could just [[GuideDangIt look up the right answers on the Internet]] or even ''guess'' them.
* PowerUpFood: The meals you can buy at the restaurant all increase your Digimon's stats a bit. Can be abused for rather [[GameBreaker game breaking]] results thanks to a certain GoodBadBug.
* PreexistingEncounters
* RoadRunnerPC
* RunDontWalk
* SavePoint: Whenever your Digimon sleeps.
** JustifiedSavePoint: In Jijimon's house.
* SavingTheWorld: At least, the Digital one.
* ScratchDamage
* ScriptedEvent
* SequenceBreaking: Certain characters in the final few sections of the game appear regardless of whether or not you've done the quests which would presumably be required. Leomon, for example, gets a small role in the ending sequence regardless of whether or not you've spoken to him, and although the Grey Lord's Mansion quest introduces [[spoiler:Devimon]], a Digimon fought as a boss in a different part of the game, it's possible to do them the other way round.
** In addition to this, advancing the Ogremon subplot to the point where he takes over the Drill Tunnel before you recruit Meramon makes Meramon unrecruitable and the post-earthquake shortcut to Mt. Panorama permanently unavailable. Under these conditions it's still possible to beat the main storyline of the game, but you can no longer unlock all the medals and can't achieve HundredPercentCompletion.
* SideQuest: The whole game is made up of mostly optional quests, as there are only two Digimon you must recruit to get to the final main dungeon. The other numbers can be made up from any of the quests.
* SoundTest: Giromon's jukebox. However, it is rather infamous for [[GameBreakingBug crashing the game]] if one attempts to use it in the North American version of the game. [[RegionalBonus It works just fine in the PAL version, though.]]
* SpellMyNameWithAnS: [[spoiler: Analog''man'', not ''mon'']].
* StandardStatusEffects: There's your workaday poison, stunning and confusion effects, but there's also a bizarre status effect where the affected Digimon briefly turns into a flat, pixelated Virtual Pet version of itself. While in this state, it can only attack with weak but [[CursedWithAwesome occasionally disruptingly fast]] pixel attacks. While transforming in and out of this state, the monster is completely invulnerable.
* StatGrinding: The damned Gyms.
* StupidityIsTheOnlyOption: More than once, to boot. Getting insulted by a bratty Otamamon? [[DisproportionateRetribution Let him have it]]. Bringing a sick Digimon who can't stand the cold to the local SlippySlideyIceWorld? [[CrueltyIsTheOnlyOption Brilliant idea]]. Walking to a clearly unstable piece of land on the edge of a cliff? [[TooDumbToLive Even better!]]
* SuicidalOverconfidence: To the point it's annoying.
* TalkToEveryone: Almost subverted when Angemon is recruited as between him and Jijimon you can just about work out where the heck to go next via fairly obscure riddles.
* TalkativeLoon: Giromon.
* ThatOneSideQuest: Getting Monochromon to join the city is an exercise in patience.
** Recruiting Penguinmon means having to play a difficult curling mini game that means having to get a higher score than him. This can either be incredibly easy as Penguinmon has a tendency to make bad decisions, but can also be frustrating as at times, he knows exactly what he's doing. Getting a perfect score is nearly impossible.
* ThePowerOfFriendship: [[spoiler: The final battle is Analogman's attempt to prove that slave Digimon are better than friend ones.]]
* TheVoiceless: Your partner is the only Digimon who doesn't talk, although the speech bubbles expressing his various needs are implied to be speech.
* ToiletHumor: Filth-type moves, as well as Numemon and Sukamon and variations thereof.
* TrainingFromHell: In Trash Mountain, you'll find one of the little gyms scattered around the game world. This particular gym makes your Digimon ''dive into a giant pile of poop and stay there'' to somehow increase their MP.
** It's also notable as being the only training exercise that decreases your Digimon's happiness when you do it. They REALLY don't like having to wade around in poop for an hour.
* TranslatorMicrobes: Mentioned early in the game; the player's character thinks he's speaking his own language, but other characters claim he's speaking theirs.
* TunnelKing: The Drimogemon living in Drill Tunnel.
* UndergroundMonkey: Some of the [[PaletteSwap Palette Swapped]] NPC Digimon are this, for example the Snow-Agumon and Mud-Frigimon. Their recolorings and skillsets are implied to be adaptations to their environments.
* UniversalPoison: Inflicted by some Nature and Filth techs. Anything inflicted by it will take damage over time and only walk during a fight.
* {{Unwinnable}}: Whether it's by mistake or design is uncertain. It ''is'' certainly possible to get stuck if you enter Jijimon's house - on more than one occasion - because as you leave his house (usually just after saving), a powerful Digimon attacks you with no warning. You can, however, just die and wait to get to Champion level again before the opponent re-appears.
* VideoGameCaringPotential: On the long run, it pays to properly take care of your monster. Not only does it usually result in better digivolutions, but full happiness and discipline increase the Digimon's lifespan and the time it takes for it to poop once the appropriate speech bubble shows up, respectively.
* VideoGameCrueltyPotential: Basically, you can deprive your Digimon of sleep, scold them hundreds of times for no reason, and even make them crap themselves. Some of these are ''required'' at least once if you want to complete the Digivolution chart. Oh, and did we mention you can do this to the ''[[MoralEventHorizon baby]] [[KickTheDog level]]'' Digimon? Note that neither of said actions will go unpunished, but still...

* WhatTheHellHero: Frigimon calls you out on bringing a Digimon who can't stand cold to [[SlippySlideyIceWorld Freezeland]]. He refuses to come to the city until you come back with a Digimon who doesn't mind the freezing climate.
* YearInsideHourOutside: Apparently time runs more slowly in the digital world; the ending implies your character has only been there for a few real-world hours, and he theorises that that's why he doesn't have to eat or sleep in that world. Confusing this is the fact that it has its own time system, which works on a cycle of approximately half-hour days.
