Video Game: Digimon World Dawn Dusk aka: Digimon Worlddawn Dusk
A pair of games for the DS and the sequel to Digimon World DS, 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 Digimon World 3, there's plenty of Fanservice, with dozens of Digimon to build your dream team. And despite its 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.
Also used by the Big Bad, who combines its power with that of Chronomon, the final boss of the previous game.
Awesome but Impractical: The main story is easy enough to make most of the more powerful Megas such as 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.
Boss in Mook Clothing: 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.
But Thou Must: 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.
Camp Gay: 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.
Competitive Balance: 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.
Continuity Nod: There are various oblique references to Digimon World DS, but it's only after the final boss battle that a character namedrops Chronomon.
Crutch Character: 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.
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, 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.
Defeat Means Friendship: The standard way of convincing other Digimon to cooperate with you is to beat them in a fight.
Elemental Rock-Paper-Scissors: 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.
Fetch Quest: You have to take some side assignments from Digimon to unlock new plot missions; most of their requests fall into this.
Even Evil Has Standards / I Gave My Word: 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.
Guide Dang It: 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.
Heroic Mime: Your counterpart/rival from the other team/game gets speaking lines, but not you.
Lethal Joke Character: Used in the battle against 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)
Light Is Not Good: In the Dusk version Light Fang is brainwashed by the Big Bad and the majority of the game is devoted to fighting them.
Level Grinding: 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. Have fun.
Magikarp Power: 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.
Now, Where Was I Going Again?: 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.
Number of the Beast: You need 6666+ experience from fighting Beast-attribute Digimon to Digivolve Myotismon to VenomMyotismon, and at Level 66, to boot.
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.
Overly-Long Name: 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.
Omnicidal Maniac: What Grimmon's motivation becomes after he is defeated as Chaosgrimmon and digivolves into Exogrimmon.
Plot Armor: The main character is immune to the data-erasing waves used by the Big Bad, 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.
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.
