* ''VideoGame/TheEvilWithin2'': Photo slides. Spread around town, are small slides Sebastian can collect; gathering all 10 of them unlocks an 11th one that gives a SequelHook to the game.

* ''VideoGame/DeathsDoor'': Shiny Things. Over the course of the game, the player can find random collectibles, which can give hints about the world and the lore of the world, but they're usually hidden away and require investigating. Only one of them is necessary to complete the main story, but three of them are necessary for the post-game: Old Photograph, used to solve a puzzle and find the secret garden; Rusty Belltower Key, to access the belltower; and the Mysterious Locket, which unlocks a BonusBoss fight necessary for the SecretEnding.

** ''[[VideoGame/TheLegendOfZeldaTearsOfTheKingdom Tears of the Kingdom]]'' returns with Korok Seeds and replaces Spirit Orbs with Lights of Blessing, both of which have seen an increase in number. There's also Sage's WIlls to increase the power of the Sage's Avatar that follows you around, Bubbul Gems which can be traded to an NPC for monster parts and monster gear, Poes for rare items at specific statues, and Crystaline Charges which can increase your battery meter.

** Statues won out of a machine in ''[[VideoGame/TheLegendOfZeldaTheMinishCap The Minish Cap]]''.

* Every ''VideoGame/PajamaSam'' game had something new you had to find (socks in the first game, cookie tops in the third game).

** Secret Seashells in ''[[VideoGame/TheLegendOfZeldaLinksAwakening Link's Awakening]]''.

** ''VideoGame/KingdomHeartsII'': The ''Final Mix'' version adds 144 puzzle pieces to grab throughout the worlds, which are then used to piece together 6 images. Once you complete an image, you are rewarded with a rare or one-of-a-kind item.

Many games (especially [=RPGs=]) have some kind of optional collectible hidden throughout the game, usually to have [[TwentyBearAsses no purpose]] but to be required for HundredPercentCompletion. But there are frequently rewards for getting certain numbers of them, and [[GottaCatchThemAll collecting them all]] often gives you a powerful ([[BraggingRightsReward but frequently unneeded]]) item, or unlocks a super-hard BonusBoss.

* Red jewels in ''VideoGame/IllusionOfGaia'' are found throughout the game, with a grand total of fifty of them. Collecting them and talking to the Jeweler gives Will various upgrades, including longer health bars and bonuses to special attacks. The trouble is that most of these jewels are {{Permanently Missable|Content}} after completing certain dungeons since [[PointOfNoReturn leaving a continent means you can never return to it]]. The red jewels [[PixelHunt are found in very obscure places]], and the game gives you no hints whatsoever about where they might be located. Managing to find all fifty is difficult, but doing so provides access to the BonusBoss. The original SNES release was also nice enough to include the locations of all fifty red jewels in its instruction booklet, just because they were so hard to find.

* ''Videogame/TalesOfSymphonia'' has the Devil's Arms, which are weapons which grow more powerful the more enemies you beat with that character, making them potential GameBreaker equipment. Collecting them all gives you access to a BonusBoss.

Many games (especially [=RPGs=]) have some kind of optional collectible hidden throughout the game, usually to have [[TwentyBearAsses no purpose]] but to be required for HundredPercentCompletion. But there are frequently rewards for getting certain numbers of them, and [[GottaCatchEmAll collecting them all]] often gives you a powerful ([[BraggingRightsReward but frequently unneeded]]) item, or unlocks a super-hard BonusBoss.

** Catching all Pokémon. Despite early games even having the tagline of "GottaCatchEmAll" in Western markets, no game in the series actually ''requires'' you to do this outside ''VideoGame/PokemonLegendsArceus''[[note]](and even then, that's just for the TrueFinalBoss; you can beat the main game by only catching a mere ten Pokémon if you know what you're doing)[[/note]]. Your reward for doing so is [[BraggingRightsReward a diploma]], with Gens III through VI giving you separate ones for the Regional Pokédex and the National Pokédex. Completing the National Dex in Gens V through VI, and the Regional Dex from Gen VII onward, also nets you the Shiny Charm, an item that increases your chances of finding Shiny Pokémon. And none of these rewards require you to get any Mythical Pokémon, due to those being TemporaryOnlineContent.

* The ''{{VideoGame/Bayonetta}}'' series has the Umbran Tears Of Blood, half of which are collected through an AchievementSystem and the other half through [[GottaCatchThemAll collecting small crows scattered through the various levels]]. The first game featured a whopping 101 Umbran tears (50 Achievements/51 Crows), and the [[{{VideoGame/Bayonetta 2}} sequel]] had just 50 (30 Achievements/20 Crows). In both games they unlock the same accessories, Eternal Testimony (automatically replenishes 2 Magic Orbs when empty) for collecting half the Tears, and the [[GameBreaker Climax Bracer]] (endless [[SuperMode Serious Mode]] in the first game, endless magic in the second) for getting all of them. There's also the many Journals that can be collected throughout the levels, but beyond getting all of them being a requirement for getting one of the Umbran Tears, all they do is [[StoryBreadcrumbs give backstory for characters, history, and locations in the game]].

* In the ''Franchise/SpyroTheDragon'' series, you have to find all of the gems and all of the eggs for 100% completion.

* The ''Mystery Trackers'' series have an achievement that involves finding all the frogs in a particular game, while several other hidden object games have one for "void objects", which shift from one object to another and then back again.

** Golden Skulltula tokens in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]''. Also in ''VideoGame/HyruleWarriors''.
** Masks in ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]''. There are also collection quests in specific areas, such as Skulltula Tokens (in Skulltula Houses) and Stray Fairies (dungeons).

** A variety of collectibles in ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'', such as Treasure Charts, enemy drops, and delivery items.

** The Poe Souls and golden bugs in ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]''.
** Treasure Charts and Spirit Gems in ''[[VideoGame/TheLegendOfZeldaPhantomHourglass Phantom Hourglass]]''.
** Train parts, Rabbits, and stamps for the stamp book in ''[[VideoGame/TheLegendOfZeldaSpiritTracks Spirit Tracks]]''.

** ''VideoGame/NoMoreHeroesIII'': There are many collectibles and similar quantifiable features that are tied to sidequests, and can be found as Travis explores Santa Destroy and the other playable cities: Scorpions that Travis has to grab carefully and deliver to a Sushi kiosk close to the No More Heroes motel, Moai statues Travis is tasked to destroy, soils where he is tasked to plant magical seeds so they grow into WESN-generating trees, spots where Travis has to spot a doppelganger of his, clothes he can earn from friendly aliens by meeting specific conditions, and stickers he can deliver to Bishop. There are also gacha figurines he can earn from dispensers in a room within the motel.

* ''VideoGame/NoMoreHeroes'' features this in the form of collectible cards. You must beat the game ''twice'' minimum if you fail to acquire one of the cards on a playthrough. The second playthrough allows you to collect a new, different, second set of cards. Other collectibles include Lovikov Balls (which are used to earn new skills) and unique T-shirts hidden in the city of Santa Destroy.

* ''VideoGame/{{Splatoon}}'' has the Sunken Scrolls. One is hidden in every single player level, and each of them [[StoryBreadcrumbs reveals different details about the world of the game]], from about the Inklings, Octarians, and various other creatures that inhabit it, to its backstory.

* ''VideoGame/MarioParty4'': There's a total of 60 birthday presents to collect in the game, and getting them all is a tall order: For each playable character, there are six presents that can be earned in Story Mode by becoming the Party Star of their respective boards (defeating the hosts in minigames is also required); since there are eight playable characters in the game, this means Story Mode has to be played at least eight times (once with each character) in order to gather 48 presents from that mode alone. Then there are 11 additional presents based on the boards' hosts, acquired by breaking records in certain minigames, and finally an extra present given when all others were earned.
