* In ''[[VideoGame/FireEmblemElibe Fire Emblem: the Sword of Seals]]'', the Bonus Stage Collectables were found in the form of the eight legendary weapons. The eight legendary weapons must be obtained from completing [[BonusStage gaiden chapters]], bonus levels that could only be accessed if the previous normal chapter had all its hidden objectives fulfilled (such as completing the level before an X amount of turns have passed, keeping specific units alive, ETC) upon completion. To progress to the final arc of the campaign and gain access to the GoodEnding, you must obtain all eight of these weapons AND keep them (as well as the SwordOfPlotAdvancement and the CuteMonsterGirl's weapon) intact (they must have at least 1 charge left) before completing Chapter 22. (Obviously, said CuteMonsterGirl [[MacGuffinGirl also needs to be alive.]])

Most popular with side-scrollers on the 16-bit era, particularly on the SegaGenesis[=/=]Mega Drive which had battery save on far fewer games.

* ''{{Pickory}}'' features various "secret items" to collect, most of which are hidden in optional secret levels. They do not currently unlock anything, so it's just for the extra challenge.

* ''{{Ristar}}'' has a bonus stage in every level, each with its own treasure. There's only one chance to get each treasure (and only if the bonus stage for that level is found). More treasures reveals more secret codes at the end of the game.
* ''[[VideoGame/CoolSpot Cool Spot]]'' has [=UNCOLA=] letters. You need a certain number of [[LawOfOneHundred spots]] (depending on the difficulty) to play the bonus round after each level, and hopefully get a letter. The best outcome is to collect and keep them all, but they can be turned in for a continue each.

** SonicCD had Time Stones in the Special Stages; no Super Sonic, but getting them all and finishing the game would result in the good ending. Interestingly, there's an alternate way: if you destroy the generator found in every level's Past version, you get the good ending without needing the Time Stones.

** ''Videogame/CrashBandicoot2CortexStrikesBack'' had hidden or otherwise hard-to-get gems that would open a new ending once all of them were collected.

** ''[[VideoGame/Sonic3AndKnuckles Sonic And Knuckles]]'' had a limited number of big rings hidden throughout the game which each gave one chance at an emerald. In addition to Super abilities for Sonic & Knuckles, a final, secret stage could be unlocked if the emeralds were collected as Sonic. However, as mentioned later, locking ''Sonic 3'' onto the cartridge would allow for battery saves, and infinite shots at the challenging special stages.

** The 8-bit versions of ''Sonic 1'' and ''2'' for the Game Gear and Master System had the Chaos Emeralds hidden within certain stages. Later 8-bit Sonic games such as ''[[VideoGame/SonicTheHedgehogChaos Sonic Chaos]]'', ''[[VideoGame/SonicTheHedgehogTripleTrouble Sonic Triple Trouble]]'', and ''[[VideoGame/SonicBlast Sonic Blast]]'' required the emeralds to be obtained within special stages, much like the 16-bit Genesis/Mega Drive games. Like the 16-bit version of ''Sonic 1'', each game only has six (except for ''Sonic Blast'', which has five).

* CoolSpot has [=UNCOLA=] letters. You need a certain number of [[LawOfOneHundred spots]] (depending on the difficulty) to play the bonus round after each level, and hopefully get a letter. The best outcome is to collect and keep them all, but they can be turned in for a continue each.

* ''PrinceOfPersia: Warrior Within'' had optional, hidden life upgrades spread across the game. Finding all of them was necessary to obtain the [[InfinityPlusOneSword Water Sword]] which lead to the game's TrueEnding.

* ''Sonic 3'' (and by extension ''Sonic 3 & Knuckles''). Unlike the other old Sonic games, this one had a battery save, so getting all the emeralds is a matter of time and persistence.

** Most new Sonic games use the chaos emeralds as straight-up {{Mac Guffin}}s. ''VideoGame/SonicHeroes'' is a recent exception where they follow this trope. There are keys in cages in various... [[GuideDangIt interesting]] locations throughout the stages. A Power character breaks the cage, and once the cage was broken the key just had to be picked up like a ring or some such. Losing your rings meant losing the key (due to this, people usually use Team Rose), and getting to the end of the stage with the key got you into the special stage after it added up your score. You could only get the Chaos Emerald if you got the key in the second stage of any theme (basically, second act) - the first act just got you points and lives. Getting all the Emeralds and completing the story for every team unlocked the Last Story (TrueFinalBoss and the true ending).

** ''VideoGame/DonkeyKongCountryReturns'' repeated this with Puzzle Pieces, which are also found outside of the bonus games, and they unlock some concept art and a music test.

* The Tawna bonus rounds in the first ''CrashBandicoot'' let you save your game if you got to the end, and two special bonus rounds had a key which each open a secret level.
* ''CrashBandicoot2'' had hidden or otherwise hard-to-get gems that would open a new ending once all of them were collected.

* ''DonkeyKongCountry'' 2 and 3 have unusual examples. You get bonus coins for completing the bonus stages, and these are required to get into the [[BonusDungeon Lost World]].
** ''DonkeyKongCountryReturns'' repeated this with Puzzle Pieces, which are also found outside of the bonus games, and they unlock some concept art and a music test.

** Later Sonic games, with a few exceptions, tied the collection of Chaos Emeralds to the plot, turning them into straight {{PlotDevice}}s.

** Later Sonic games tied the collection of chaos emeralds to the plot, turning them into straight [[MacGuffin MacGuffins]], with a few exceptions.

Usually, a bonus stage can be replayed if the Chaos Emerald in it was missed the first time, but since there are limited opportunities to play the bonus stage, collecting all of the Chaos Emeralds is never a guarantee.

* In [[FireEmblemElibe Fire Emblem: the Sword of Seals]], the Chaos Emeralds were found in the form of the eight legendary weapons. The eight legendary weapons must be obtained from completing [[BonusStage gaiden chapters]], bonus levels that could only be accessed if the previous normal chapter had all its hidden objectives fulfilled (such as completing the level before an X amount of turns have passed, keeping specific units alive, ETC) upon completion. To progress to the final arc of the campaign and gain access to the GoodEnding, you must obtain all eight of these weapons AND keep them(and a freebie SwordOfPlotAdvancement) intact (they must have at least 1 charge left) before completing Chapter 22.
