[[OneGameForThePriceOfTwo A pair of games]] for the DS and the sequel to ''DigimonWorldDS'', ''Digimon World Dawn/Dusk'' puts you in the shoes of a member of the Light Fang or the Night Crow, two rival teams who raise and battle Digimon in the Digital World. The annual tournament is cut short by a mysterious viral assault, severing all contact between the two teams and leaving both Sunshine and Darkmoon City scrambling to rebuild and figure out just what caused the incident. Naturally, both sides suspect the other had a hand in it... and naturally, it falls to you to ferret out the truth.

Like ''DigimonWorld3'', there's plenty of Fanservice, with dozens of Digimon to build your dream team. And despite its [[OneGameForThePriceOfTwo nature]], there is actually a fair amount of variation between the games, with several storyline quests differing depending on which version you're playing, although, regardless of the team you're on, the dialogues are pretty much the same.

----
!!Provides examples of:
* ATasteOfPower: All four of the starter packs you can choose from at the beginning have at least one Ultimate level Digimon. Naturally, [[BroughtDownToNormal this doesn't last...]]
* AbsurdlySpaciousSewer: The Sunken Tunnel.
* AdaptationDistillation: The Digimon here don't always follow the same evolutionary lines as in the anime. For instance, Impmon's first Mega form in ''Dawn/Dusk'' is ''Lilithmon''. Yeah...
* AGodAmI: [[spoiler:Grimmon becomes this after Chrono Core merges with him.]]
* AllYourPowersCombined: DNA Digivolution.
** Also used by the BigBad, who combines its power with that of [[spoiler: Chronomon, the final boss of the previous game]].
* AwesomeButImpractical: The main story is easy enough to make most of the more powerful Megas such as [[EldritchAbomination ZeedMillenniummon]] unnecessary when compared to the amount of time required to get them. A few of them can be examples even for most of the post-story sections.
* BossRush: [[spoiler:The Legendary Tamer Quest; it also counts as a ContinuityNod.]]
* BossInMookClothing: After you defeat the Gaia origin, and talk to the tamers in your organization, you will be able to unlock Darkdramon, Anubismon and Imperialdramon Fighter Mode in Dawn and [=SaberLeomon=], Argomon (Ultimate) and Armageddemon in Dusk. All of these unlocked Digimon are extremely powerful and will require very high stats to beat even the weakest.
** To make matters worse, the game can load more than one of them to fight you.
** Justified as you will need the experience they give if you ever plan on leveling past Lv. 70. At that point you'll be praying to meet those before every battle.
* ButThouMust: This is subverted before the battle with Grandracomon. You can tell him to pay for Kowloon Co's services himself and fight him or pay him 100000 bits and get the Kowloon Blade.
* CampGay: Any Digimon can have the "Prissy" personality, which makes them talk and act like a stereotypical teenage girl...even if the Digimon is obviously male.
** Of course, Digimon have no gender (more accurately, no sexual difference between genders), so this was bound to be happen.
* CompetitiveBalance: Actually done cleverly. At the start of the game, a Dawn player has an automatic advantage over a Dusk player simply because ''Dawn'''s mascot and likely another of their Digimon has an element advantage over the ''Dusk'' version's mascot and likely other team member. This is compensated for because it's much easier (and quicker) to Digivolve the mascot of ''Dusk'', giving her an advantage over ''Dawn'' players.
* ContinuityNod: There are various oblique references to ''DigimonWorldDS'', but it's only after the final boss battle that a character namedrops [[spoiler:Chronomon]].
* CrutchCharacter: Your starting Coronamon or Lunamon are like this. After your other two starters are degenerated to level 1, those two are still at level 20 and will be stomping most opponents in the early game. However, their stat growth drops exponentially at higher evolutions, and by the endgame you will likely have switched in something else to use in battle.
* DarkIsNotEvil: In the Dusk version at least.
** It's more or less like the Digimon in the cities are normal citizens. However, all of the bosses who pose a threat to the Digital World are either Dark-type or at least look evil.
** To clarify, Darkmoon City Digimon and Night Crow are not evil no matter the version you play, [[spoiler:though like Light Fang below, they do get brainwashed into fighting you for most of the game in Dawn.]] All the other dark/virus type Digimon not associated with them are.
** Gaia Origin has several Dark Digimon in its ranks, including Apocalymon, but they aren't evil by any stretch. The aforementioned Apocalymon is one of the ''nice'' ones. So is [=ZeedMillenniummon=], whose official designation is an ''Evil God'' type and is fairly reasonable to the player.
* DefeatMeansFriendship: The standard way of convincing other Digimon to cooperate with you is to beat them in a fight.
* DistaffCounterpart / SpearCounterpart: Chief Julia to Chief Glare and [=ChaosGallantmon=] to Ophanimon. Their lieutenants also follow this.
* DreamingOfThingsToCome: It's a sort of ''game mechanic.'' If you lose a fight, you're transported back to your house, appear next to your bed, and told that you were having a bad dream. A great improvement on the last game, which simply had you teleported back to the overworld.
* DubInducedPlotHole: The HiveMind interactions between Alphamon and Omnimon are less of a BigLippedAlligatorMoment when you realise the latter is named ''Omegamon'' in the original Japan version.
** Minor, but Night Crow was supposed to be Night ''Claw'', as a counterpart to Light Fang.
* EmbarrassingRescue: In Dusk, Gutts is particularly bad about this.
* ElementalPowers: Each Digimon is assigned being resistant to one attribute and weak to another. The following elements are:
** BlowYouAway: Wind
** CastingAShadow: Dark
** DishingOutDirt: Earth
** ExtraOreDinary: Steel
** HolyHandGrenade: Holy
** MakingASplash: Water
** PlayingWithFire: Fire
** ShockAndAwe: Thunder
* ElementalRockPaperScissors: With some odd category assignments: grouping Insect and Plant Digimon together makes some degree sense, but as Lightning-elementals? The sequel did fix this by making them different species, however.
* FetchQuest: You have to take some side assignments from Digimon to unlock new plot missions; most of their requests fall into this.
* EvenEvilHasStandards / IGaveMyWord: Kowloon Co will only help you if you defeat them. After you do so, two of the members suggest bailing, but their leader invokes both these tropes, stating that while they're criminals, they never go back on their promise.
* GuideDangIt: Not just for DNA and Special Digivolving; you can't even get most of the Digimon quests without having certain Digimon with certain personalities...
** Some of the [=NPCs=] on the other areas of the digital city mention some combinations for DNA digivolution and the correct Digimon+personality needed to unlock special missions. A large portion aren't mentioned.
** The Digi-Eggs. Many of them are fairly simple; others require specific Digimon at specific levels. Fortunately, this mechanic is completely optional for completion.
* HeroicMime: Your counterpart/rival from the other team/game gets speaking lines, but not you.
* LethalJokeCharacter: Used in the battle against [[spoiler:Imperialdramon Paladin Mode. The boss is supported by Minomon and Kuramon, two Digimon of the lowest Digivolution level in the game. They both have stats to rival many Mega Digimon and a variety of amazing techniques]].
** You can invoke this yourself by raising an In-Training Digimon's Aptitude high enough and leveling them up until they learn ridiculously powerful Techniques (at around level 50-60)
* LightIsNotGood: In the Dusk version [[spoiler: Light Fang is brainwashed by the BigBad and the majority of the game is devoted to fighting them]].
* LevelGrinding: You'll have to do loads and loads of this to max out your Digimon's stats in order to stand a chance in PvP.
** From the beginning to end. Should the player not use the passwords in the Coliseum to start the game with the Legendary Sword, Legendary Armor and Legendary Ring, even the early enemies can take a while to beat. And more traditional players will be in for a surprise since the real way to enhace stats is by repeatedly degenerating the Mons so they go back to the previous evolution stage with higher stats. Should one simply level up and evolve them when it can be done, eventually the bosses will overwhelm the team.
** Ironically, beating the weakest enemy in the game in enough to raise any Digimon from Level 1 to 3. Then the experience needed start to grow exponentially. And if you're actually building a team for PvP, you'll need to level one Digimon to 70, 80 or 90 several times. [[{{SarcasmMode}} Have fun.]]
* LostForever: The Kowloon Blade... [[JokeWeapon not that it matters, due to its pitiful stats when you get it.]]
* MagikarpPower: All of the In-Training stage Digimon learn the move Rainbow Spit, which hits twice for heavy damage... at level 60. Learning it before hitting Mega level for the first time is unlikely.
* MythologyGag: Quite a lot, and mostly to the anime series in the form you get some digimon, not limiting it to just the very appearance of digimon that appeared in the series at some point:
** Apocalymon can only obtained by fusing members of the Dark Masters. The Dark Masters themselves can only be obtained in an specific order.
*** There's an slight one to Piedmon's status as the leader, The requirements to get the Dark Masters are made so Piedmon is the last one you can get. He is also the only one of the Dark Masters to not have one of his skills at level 4 and instead has all his skills at level 5.
*** Metalseadramon's status as TheLastOfTheseIsNotLikeTheOthers, in the series, Metalseadramon is the only Dark Master whose attribute is NOT virus, here, Metalseadramon is the only Dark Master whose type is not in the side of Night Claw.
** Both of Myotismon's evolutions: It can only evolve to Venommyotismon while having an ally Demidevimon, and Malomyotismon can only be evolved to while having an ally Arukenimon.
** Beelzemon Blast Mode can only be obtained by fusing it with a Bancholeomon.
** Some Digimon that were main partners in the anime series can reach their supermode from that series, even if said form is something really specific and unique to the series in which it apeared.
* NowWhereWasIGoingAgain: Partly averted; you can look up your current Quest in the menu at any time. Of course, when you don't have a quest...
** Exploring can be really tedious as you have no map and the later areas are pretty much big mazes with several dead-ends. Couple this with a extremely high random encounter ratio plus no means to repel those encounters and even the most basic missions can be a chore to do.
* NumberOfTheBeast: You need 6666+ experience from fighting ''Beast''-attribute Digimon to Digivolve [[spoiler:Myotismon to [=VenomMyotismon=]]], and at Level 66, to boot.
* OneGameForThePriceOfTwo: You can't collect all the Digimon without trading with others or fighting on Wi-Fi.
** You also need to use multiplayer modes to access the top-level Tamer challenges.
*** In an extremely odd case, almost everything can be gotten as long as you have someone to play with, even if both players are using the same game. The version exclusive mons, for example, are obtained by matching Digimon. Matching a Greymon with a Dinohumon can result in a Guilmon egg, Guilmon being a Dawn exclusive and Greymon and Dinohumon being available in both versions.
* OverlyLongName: You're only allowed eight letters to name a Digimon. This means that a vast majority of actual Digimon names won't fit at all, not even basics like "Garurumon". This is because the allotted number of characters was unchanged between Japanese and English. While Digimon names usually take far less than eight characters in Japan, well... you can see where we're going with this.
* OmnicidalManiac: [[spoiler:What Grimmon's motivation becomes after he is defeated as Chaosgrimmon and digivolves into Exogrimmon.]]
* PlotArmor: The main character is immune to the data-erasing waves used by the BigBad, meaning only he/she can stop him. The game's justification is that the attack requires a lot of power to use, and the player's character gets there after the first attack. Still doesn't explains the second and third waves, though.
** The justification for this attack's effectiveness before and during the final battle is supposed to be the PowerOfFriendship protecting the PC, but this is lost on most players, who [[TheScrappy cannot consider]] [[EmbarrassingRescue most of]] [[TheLoad the npcs]] [[FlatCharacter to be friends]].
** It does works on later encounters(like in access glacier), is just that the player character breaks through it by [[{{Determinator}} willpower alone]] and in the final battle he/she gets up because of everyone [[HeroicSecondWind cheering for him/her]] after being hit by it, furthermore, the first time, chief Julia/Glare actually stands it(and their digimon aren't degenerated) which is the reason grimmon used it more times in order to actually weaken him/her, which is the reason the effect wasn't strong enough on the player, for the chiefs to be affected they(and their digimon) had to be slowly inffected by a virus and they recovered faster than the other affected characters.
* PublicDomainSoundtrack: Johannes Brahms's Hungarian Dance No. 5 is used for some background music choices on the player character's islands.
* PurelyAestheticGender: Might be why they let you rename your Digimon whenever it digivolves; seeing [[{{Gonk}} Vilemon]] become [=LadyDevimon=] is... interesting.
** Similarly, [[OurGoblinsAreDifferent Shamamon]]'s final form is [[spoiler: [[DarkMagicalGirl Kuzuhamon]]]].
** Also, your own gender selection functions like this due to some odd translation choices, which you're likely to find out by talking to your Digimon; among other things, they'll ask your female avatar if you have a girlfriend...
*** When your gender is brought up by other characters it will be male, even if you're the girl. This is because the Japanese version only had one script, with gender-neutral pronouns, and the translators did not bother to create a new one.
* StandardStatusEffects: Mostly averts UselessUsefulSpell by attaching these to normal, damaging moves as potential side-effects.
* SuperpoweredEvilSide: [[spoiler: Ophanimon in ''Dusk'', [=ChaosGallantmon=] in ''Dawn'']].
* SuperTitle64Advance: Following suit the RunningGag of many NintendoDS games, the cities the two rival teams are stationed in are called '''D'''arkmoon and '''S'''unshine.
