History Main / HundredPercentCompletion

* All of the main ''VideoGame/{{Skylanders}}'' games have been designed to be played with physical buyable action figures that connect to the console and become a playable character. The thing is that certain areas can only be unlocked by a specific group of Skylanders, and the starter pack only gives you three or two of them. A level's star objective list has a specific star that's only earned once all the collectables in a level. Meaning that if you want to earn all 3 stars on a level, you're gonna need one Skylander of every element, on top of the bonus levels that some games have available for you to buy that are sometimes lumped in with the rest of the completion total. And with the later games, certain areas can only be accessed by that games main gimmick Skylanders.

** Superchargers thankfully calms things down. Now in order to get 3 stars on a level, you just need to complete each vehicle type's mission, lessening the need to buy all the toys since any Skylander can drive a vehicle. Element Gates were removed, replaced by Supercharger Gates, which any Supercharger of any element can access. And by Imaginators, the three-star goals can easily be accomplished with just one Skylander, without the need to buy any toys outside of the starter pack characters.
*** However, for true 100% completion in Imaginators, you're gonna need to buy one Sensei of each element to unlock the "Sensei Realms", short mini levels that have their own set of star objectives to complete. And the game also received a content update adding two more levels only accessed by other toys... which are now incredibly expensive due to their low print run.

* All of the ''VideoGame/{{Skylanders}}'' games have been designed to be played with physical buyable action figures that connect to the console and become a "character". The thing is that only certain characters can unlock certain doors or open certain chests and in the base game box only brings three of them. And guess what? If you don't do all of the side quests and don't receive all of the treasures and open all of the chests of each level, you can't gain the Three stars corresponding to said level. And as stars are the only thing counting on the "player's level", one cannot unlock new things until they get to certain level. Thus, making it impossible to accomplish the one-hundred-percent until you have bought at least one of each type of character [[note]]and the character stays alive long enough to get to the door or chest that only it can open, which means the player has to level-up each new character he bought, to the point it can stand a chance in the advanced levels[[/note]]. This includes characters unique of old versions of the game, as the case of "giants" for some chests, thus making it the perfect merchandising market.

* The ''VideoGame/LocoRoco'' games have a goal of obtaining 20 [=LocoRoco=] in each level (which is tougher than it sounds), as well as excessive RandomlyDrops-LevelGrinding to completely build the [=MuiMui=] house. Also, one of the [=LocoRoco=] 2 unlockable levels seems to assume that people are going for this trope, much like a Yoshi's Island GBA-exclusive level is (see its entry below). The goal is just downstream (really), while the challenge comes in WreakingHavok upon realistic JumpPhysics to obtain all 20 [=LocoRoco=].

* ''[[Franchise/{{Pokemon}} Pokédex 3D Pro]]'' has an extensive list of things to do for completion - reading every entry, seeing every AR Code, finishing the 35 main quizzes, and remembering all but two of the Pokémon in one form or another in the quizzes. However, finishing the 35 quizzes unlocks another 34 to beat, each Pokémon has 4 aspects about it that can be remembered (appearance, entry text, cry, and type) with points for each, and how many quizzes you got perfect. In Japan, there are also passwords that can be used to unlock a few other things, including one of the two missing entries.

** Nippon Ichi is notorious with this for every strategy game they make. ''VideoGame/PhantomBrave'', ''VideoGame/LaPucelle'', ''VideoGame/MakaiKingdom'', they all have the same inherent problem with finishing off all of the content. What makes ''Disgaea'' worse is that it's NIS's longest running franchise and thus has the most callbacks and extra characters, but no matter what strategy game with the NIS/NISA logo you're playing, you're in for an RNG hellscape.

** It takes hours of searching to 100% complete ''VideoGame/KirbyAndTheAmazingMirror'', even with the Master power.

* Achieving 100% item completion in the Franchise/{{Disgaea}} games put you at the mercy of the RandomNumberGod, since a large number of drops can only be gained by either earning them through bonuses (whose availability is limited to certain tiers of the Item World) or stealing them from enemies (who spawn with any number of random equipment). VideoGame/DisgaeaD2 makes this marginally easier by increasing the rarity value of any (non-Legendary) item once you've completed all of the floors of its respective Item World, but with many items still remain unavailable for purchase it's still a toss-up whether you'll be able to get a significant percentage of them.

* VideoGame/StarCraft2 has an achievement system, with every stage in each campaign having three objectives. The first is often just beating the stage, the second is usually some simply challenge, and the third is a harder challenge that often requires you play on higher difficulties. In addition to this you also have class XP which can be gained in any multiplayer map and rewards you with new portraits and dance commands for units as joke. You can also clear some multiplayer challenges such as winning a certain number of matches or getting a specific victory against AI. The Co-op mode also has individual challenges for each commander that reward portraits, each character can be leveled up to level 15 with new abilities unlocking as you go, Class Mastery for all classes which can go up to Level 90, and Ascension levels with go up to 1000 and are entirely cosmetic outside of showing off how much you play.

** 100% in ''[[VideoGame/KirbysAdventure Kirby: Nightmare in Dream Land]]'' allows you to play through again, but this time as series badass Meta Knight. [[CheckPointStarvation You can't save, though]]. In the original NES game, 100% completion will unlock [[NintendoHard Extra Mode]], which disables saving and cuts Kirby's maximum health in half.

* The Trophy system for UsefulNotes/PlayStation3 and UsefulNotes/PlayStation4 games has a tier called Platinum trophies. Every game that has it awards the Platinum trophy for the same thing: collect every other trophy in the game. Thus, earning a game's Platinum Trophy is synonymous to getting Hundred Percent Completion on it.

** ''VideoGame/TheLegendOfZeldaPhantomHourglass'' and ''VideoGame/TheLegendOfZeldaSpiritTracks'' have the ship/train parts collection, which are infamously obtained through random loot renewed daily. Some of these are at the very bottom of the Temple of the Ocean King and the Lost at Sea Station respectively, meaning you'll visit these dungeons again and again and again, every day, if you want to completely fill your collection. It's pretty telling that ''Spirit Tracks''[='s=] [[https://www.speedrun.com/lozst/full_game#100 100% speedrun category]] does not include train parts.

* In both ''VideoGame/CastlevaniaChroniclesOfSorrow'' games, ''Aria of Sorrow'' and ''Dawn of Sorrow'', Soma not only has 100% map completion to look forward to, but 100% soul collection as well. Every non-human enemy in the game, save for their respective final bosses, has a soul that will randomly drop when Soma kills it, giving him a new power to play around with. Obtaining the soul of every enemy in the game will give him access to the infinite-MP [[GameBreaker Chaos Ring]]. Needless to say, this is extraordinarily difficult, with some souls refusing to drop until you slaughter the enemy 100 times or more.

* In ''VideoGame/{{Bayonetta}}'', the achievements/trophies are actually a part of the game in the form of "Umbran tears of blood". Getting the 51 achievements ''and'' catching the 51 crows hidden throughout the game (both required to beat the hardest difficulty setting) will give you the [[BraggingRightsReward Climax Bracelet]], a GameBreaker item. And if you are really hardcore, you can collect 10 million halos to fight a NintendoHard BonusBoss − for which the aformentioned Climax Bracelet will actually be useful − who will reward you with a secret weapon. Which you can use in the BonusLevelOfHell Angel Slayer, to unlock a new character named [[OneHitPointWonder Little King Zero]]. And if you ''still'' don't have enough, try and get platinum awards in every chapter on Normal to unlock Jeanne as a playable character. Pfiou!

** ''VideoGame/{{NieR}}'' (which takes place in the future of the fifth ending) uses the same formula for getting all the endings, but the weapons are infinitely easier to get. Unlike ''Drakengard'', however, the endings are more climactic and all {{Tearjerker}}s.

** In ''VideoGame/KingdomHeartsI'', you have to lock all the worlds, rescue all the Dalmatians, and beat the Hades Cup to get an extra bonus movie after the credits. A later release of the game requires you to do all the Trinities and beat Kurt Ziza as well, but gives you a longer movie. ''Final Mix'' ups the ante some: to get the extra long secret movie, you have to rescue all 101 Dalmations, find every Trinity mark, play every minigame at least once, and beat every single enemy in the game, which includes the [[BonusBoss Bonus Bosses]]. Unless you play on Proud Mode, in which case you merely have to lock all worlds and beat the Hades Cup.

** The ''Octo Expansion'' DLC doesn't require you to beat every level ([[NintendoHard mercifully]]), but you'll need to aim for 100% completion if you wish to see the bonus chatlog, get all of the available gear, and [[spoiler:fight the BonusBoss.]] Go even beyond that to get 1000% completion by beating every level with every weapon and [[spoiler:beating the Inner Agent 3 boss battle]], and the game will acknowledge your efforts with a nice Kamabo Co.-themed flair on Agent 8's CQ-80 menu, with the text "COMPLETE" in Inkling.

* ''VideoGame/XenobladeChroniclesX'' has enough sidequests to take well over two-hundred hours to complete. The main quest with an actual 100% tally is uncovering the entire map, which is divided into hexagons, and complete one specific task per hexagon. They are either killing a [[BonusBoss Tyrant]], opening a treasure box, or completing a story mission. There are hundreds of hexagons.

* In ''VideoGame/BanjoKazooie'', collecting 100 Jiggies will extend the ending, where Mumbo shows you three secrets and talks about ''Banjo-Tooie''. In the latter game, collecting 90 Jiggies unlocks the Character Parade in Replay Mode. ''Nuts & Bolts'' gives you an achievement and a gamerpic if you get all 131 Jiggies.

* ''VideoGame/DeBlob'' is a HUGE PAIN to get 100%; not only is there a time limit, but each level takes more than 15 minutes to complete and when you finish it, the level saves your scores and resets, meaning if you go back to it it's completely unfinished and you have to do EVERYTHING over again.
** Specifically, for each stage, you have to:
*** Paint every significant object (mainly buildings), as well as all trees, billboards, landmarks, Raydians, and a blimp
*** Slam into every transformer
*** Complete every challenge, including the aforementioned landmarks
*** Find every style collectible
*** Achieve a gold medal for score, as well as one each for two sub-levels
*** And finally, complete each level in a certain amount of time

* In ''VideoGame/TheGodfather'', reaching 100% completion allows unlocks the ending where [[PlayerCharacter Aldo]] [[OriginalGeneration Trapani]] becomes the [[TakeOverTheCity Don of NYC]].

* Getting every emblem in ''VideoGame/SonicAdventure2 Battle'' unlocks a 3D version of GreenHillZone. Unfortunately, that means completing every mission with an A rank (some of which are nigh impossible, such as getting 100 rings in a set amount of time when there are only 114 rings in the level), surviving three boss rushes, one racing mini game, and beating all the races and all the levels of karate with your Chao.
** The first ''VideoGame/SonicAdventure'' did not feature the ranking system, but still had plenty of Emblems that were collected by either completing missions, finding them in the hub world, or through beating minigames. Once you had all the Emblems you had completed everything there is to do in the game, and were promptly awarded with... absolutely nothing. Sonic Team stepped up their game with ''UsefulNotes/NintendoGamecube'' rerelease by having fully playable ''UsefulNotes/GameGear'' Sonic games get unlocked as you get more and more Emblems, and once the game is 100% you unlock [[spoiler: Metal Sonic as a playable character]]. They also made it harder to 100% with a new Mission Mode that added 60 more challenges that had to be completed before reaching 100%.

* Franchise/SuperMarioBros:

* ''VideoGame/TwinRobots'': Collecting the battery, and all of the energy tiles, in each level us how you get this in the game.

* ''VideoGame/StellaGlow'': On the first playthrough, completing the game 100% is impossible due to time constraints. You'd need to reach maximum affinity with all characters, including the one with whom you can prceed to unlock the GoldenEnding, since each character has also their own epilogue which is only viewable after the credits if your bond with them is optimal. There's also the need to maximize the side jobs. All of these activities spend Free Time, of which you're only given three turns per period. Therefore, it's more ideal to wait until the NewGamePlus, where each period of Free Time grants ''nine'' turns, so you can reach maximum affinity with everyone, complete the side jobs in all their levels, and still have lots of time left to do free exploration to find goodies in the open field. Then there's the optional objectives in the main quests' missions, whose completion grants unique gear and weapons, and some of them are pretty tricky to complete unless you know what you're doing.

** ''VideoGame/TheLegendOfZeldaPhantomHourglass'' and ''VideoGame/TheLegendOfZeldaSpiritTracks'' had the ship/train parts collection, which were infamously obtained through random loot renewed daily. Some of these are at the very bottom of the Temple of the Ocean King and the Lost at Sea Station respectively, meaning you'll visit these dungeons again and again and again, every day, if you want to completely fill your collection. It's pretty telling that ''Spirit Tracks''[='s=] [[https://www.speedrun.com/lozst/full_game#100 100% speedrun category]] does not include train parts.

*** In ''LEGO Star Wars: The Skywalker Saga'', getting 100% requires you to collect '''''1166''''' Kyber Bricks, 225 minikits, 380 characters, 69 starships, 5 capital ships, 45 micro ships, and 19 datacards, unlock all 24 planets and the 19 extras tied to the datacards, complete all 9 episodes, 135 level challenges, 45 True Jedi meters, 140 side missions, 731 puzzles, 38 trials, and 10 challenges, and fully upgrade all the core abilities and all 9 character classes. Chances are by the time you finished the entire story mode, you’ll won’t even have collected a quarter of the Kyber Bricks.

* Several of the ''VideoGame/TombRaider'' games have secrets (via items or just hidden rooms) which usually contain extra health and ammo. While some of the games' secrets are nothing but bragging rights when you get 100%, the 3rd game unlocks a bonus level for you to explore and beating that gets you [[InfinityPlusOneSword all guns with infinite ammo for any level you play over]].

* ''VideoGame/Splatoon2'' silently tracks your completion of the single player "Hero Mode" campaign. Beating every level nets you 100% completion, while beating every level with every weapon nets you [[Over100PercentCompletion 1000% completion]]. You can only see your completion percentage with the [=SplatNet2=] companion phone app, though.
** The ''Octo Expansion'' DLC ([[NintendoHard mercifully]]) doesn't require beating every level with every weapon, but it does require to beat every level if you want to see the bonus chatlog, get all of the available gear, and [[spoiler:fight the BonusBoss.]] However, it is acknowledged in-game if you did beat every level with every weapon and [[spoiler:beat the Inner Agent 3 boss battle]], as you'll garner a nice Kamabo Co.-themed flair on Agent 8's CQ-80 menu, with the text "COMPLETE" in Inkling.

** 100% in ''[[VideoGame/KirbysAdventure Kirby: Nightmare in Dream Land]]'' allows you to play through again, but this time as series badass Meta Knight. [[CheckPointStarvation You can't save, though]]. In the original NES game, 100% completion will unlock [[NintendoHard Extra Mode]], which disables saving and cuts Kirby's maximum health in half. Completing Extra Mode 100% will unlock BossRush mode.

*** ''LEGO Star Wars: The Skywalker Saga'' takes it UpToEleven compared to previous ''LEGO'' games: getting 100% requires you to collect '''''1166''''' Kyber Bricks, 225 minikits, 380 characters, 69 starships, 5 capital ships, 45 micro ships, and 19 datacards, unlock all 24 planets and the 19 extras tied to the datacards, complete all 9 episodes, 135 level challenges, 45 True Jedi meters, 140 side missions, 731 puzzles, 38 trials, and 10 challenges, and fully upgrade all the core abilities and all 9 character classes. Chances are by the time you finished the entire story mode, you’ll won’t even have collected a quarter of the Kyber Bricks.

** In ''[[UpdatedRerelease Rebirth]]'', Platinum God is just defeating both end-game bosses, but True Platinum God is reserved for collecting every secrets and items, a much harder task compared to the original. The achievement for doing the same with the Afterbirth DLC gives you the [[UpToEleven 1001%]] achievement, which calls you a "Nerd x 1000000" for your time.

* The reward for Hundred Percent Completion in ''[[VideoGame/BackyardSports Backyard Skateboarding]]'' is...a board.

* The player's Guild Card in each ''VideoGame/EtrianOdyssey'' game keeps track on the achievements you meet through your adventure (they're retained in the NewGamePlus). Some of them will come to you with normal progress (complete a certain stratum, for example), but for others you have to collect all treasures from chests or defeat all bosses on the highest difficulty level available, for example (which is easier said than done, due to the series' NintendoHard nature).

* In all of the ''VideoGame/{{Suikoden}}'' games, you get the [[MultipleEndings true ending]] only if you have all 108 Stars of Destiny in your party.
** Except ''[[VideoGame/SuikodenIII III]]'', in which all you get is the ability to play through the game as the antagonist, though part of the WhereAreTheyNowEpilogue changes.
* Like most ''Tales'' games, ''VideoGame/TalesOfSymphonia'' has an item completion book which records all the items that come into your inventory. It takes two whole playthroughs and going through another 85% of the game before you complete the listing. And that was only if you were very careful in manipulating relationships between characters.
** In addition, there's also the "Monster Book", which records every monster you encounter. Since there is one point where depending on which choice you made at an earlier time the boss is different it will take at least 2 playthroughs to record every enemy. The one good thing is that, contrary to popular belief, you don't need to record all the stats (which requires you to have a certain character use a certain item on each enemy). Your reward? A title for one character.
** The more recent ''VideoGame/TalesOfTheAbyss'' has something similar. The reward for completing the item list? A title for a single character that comes with a small stat boost and access to a special store.

** Item collection fully displaces time regarding true completion in the 3D games (''VideoGame/MetroidPrimeTrilogy'' and ''VideoGame/MetroidOtherM'') for technical reasons. Completing each ''Prime'' game at 75% gets you a [[SamusIsAGirl face reveal]] during the ending, while 100% nets you a [[SequelHook foreboding]] PostCreditsScene. Note that the ''Prime'' games also have a separate percentage for the logbook scans, for which there's unlockable material for completion as well. Players of the ''Trilogy'' compilation itself can get a whopping 300% completion, or 100% per game. In the case of ''Other M'', collecting all items will unlock the path to a BonusBoss ([[spoiler:Phantoon, of ''Super Metroid'' fame]]), and defeating it plus doing the traditional escape sequence will unlock the true ending; note that Hard Mode removes all pickups, and the game ends after the traditional FinalBoss is defeated.

* In all ''VideoGame/ProfessorLayton'' games, completing all puzzles available on the base content (for which, in turn, you must have completed all stages of the special minigames, since that's the only way to unlock 15 puzzles normally inaccessible within the story mode) will also complete the ConceptArtGallery unveiled when the game is completed once. You can also unlock [[ReplayMode all story cutscenes]] and [[SoundTest music tracks]] by gathering a minimum required total of Picarats by solving puzzles. There are also collectible treasures, but they don't unlock anything.

* Going so Over the Top in this regard it's not funny, ''VideoGame/NoMoreHeroes'' for the Wii features a set of "trading cards" that the player can collect. There are 50 cards on the first run through of the game, each bearing the picture of a wrestler's mask. There are in reality a total of 150 cards in the game, ''which must be replayed a minimum of three times from clear files'' to achieve this. This fits in with the game's over-the-top nature, as the "hero" is an obsessive ''otaku''.
