* In ''Literature/HarryPotterAndTheHalfBloodPrince'', R.A.B stole the horcrux locket by drinking the poison surrounding it. Years later, the poison is back for Dumbledore.

* ''VideoGame/GoldenSun'' is {{egregious}} because in the second game, Alex discusses how poorly first-game antagonists Saturos and Menardi were at solving the puzzles, and they were so terrible, that they accidently [[spoiler:caused the incident that happened at the very beginning from the first game]].

** [[FridgeLogic So why couldn't Hermione just wait for it to refill after Harry used it?]]
** Mayby it was nearly empty because Quirrel had already been drinking from it?
** Similarly, in ''Literature/HarryPotterAndTheHalfBloodPrince'', R.A.B who stole the horcrux locket by drinking the poison surrounding it. Years later, the poison is back for Dumbledore.

* In ''[[JakAndDaxter Jak 3]]'', just how the bloody hell did [[KnightTemplar Veger]] get through the [[TempleOfDoom Precursor Temple]] and the [[DeathCourse destroyed palace]] crawling with [[EldritchAbomination Dark Makers]] before Jak? [[BadassLongcoat His coat]], that's how!

* In ''VideoGame/{{Half-Life 2}}'', you follow the refugees' route out of the city. This route is filled with headcrabs, zombies, elaborate physics puzzles, and various and sundry obstacles to overcome. How did anybody not named Gordon Freeman get through there alive? And why weren't the physics problems already solved by the time you got there? At least it's heavily implied that the zombies and headcrabs are new, as a result of the Combine strike against the railway as you make your way down. More than once you see headcrab shells land, as well. This is mentioned in the webcomic ''Concerned''. [[http://www.screencuisine.net/hlcomic/?date=2005-09-14]]

* Very annoying in ''VideoGame/EpicMickey'' where restoring your surroundings and making everything bright and colorful with ink or destroying them with thinner to make them drab and depressing determines the type of ending you get at the end of the game. All the effort spent thinning or inking specific locations disappear if you move into another area and come back again. This was the result of casual gamers in testing not understanding and grasping the idea of choice and consequence games and is set to be averted in the sequel.

* The NES game ''TombsAndTreasure'' actually lampshades this in the beginning of the game, where the guide José tells the player that the monsters inside the ruins have rearranged everything to how it was before Professor Imes and his team stepped in and investigated.

* [[AvertedTrope Averted]] in the ''DiabloII'' expansion Lord of Destruction, where the titular character is trying to corrupt the World Stone. Said stone is guarded by three incredibly powerful Barbarian warriors. How does Baal get past them? By bribing a Barbarian elder to give him an artifact that lets him stroll right by the guardians. [[ThatOneBoss The player character isn't so lucky.]]

** Justified in ''VideoGame/TheLegendOfZeldaPhantomHourglass'': the Temple of the Ocean King is controlled by an EldritchAbomination and his Phantom guards, and a skeleton outside of the Temple even tells you that the traps activate again after you leave.
*** There's also a chest that Linebeck plundered on the first floor of the Temple, but he was kind enough to close the lid so it seemed like there was still loot.
** Apparently in ''VideoGame/TheLegendOfZeldaSkywardSword'' Zelda has been moving through each dungeon ahead of Link, despite all the enemies, traps, and locked doors. She has Impa helping her for part of this, but that still doesn't explain how the traps were reset, why the doors are still locked, and how they got past the boss. Humorously, Impa berates Link for being too slow to catch up to them.
*** In the game, it's hinted that the Goddesses (Din, Farore, and Nayru) are resetting the traps, so as to test if Link is worthy [[spoiler:of wielding the Triforce]].

* As you progress through ''VideoGame/{{Portal}}'', you leave behind boxes resting on top of buttons, destroyed glass barriers, a lot of dead or disabled turrets, and various other markers of your presence. Some of these obviously can be reset by [=GLaDOS=]; others, less so. So who went through the testing chambers [[spoiler:(and even the behind-the-scenes areas of the game)]] cleaning up after [[spoiler:the person who went through before you]]? Extra points for asking how directional arrows and stuff, drawn on walls that are pretty impossible to reach, got there.
** And then ''VideoGame/{{Portal 2}}'' [[http://www.youtube.com/watch?v=tax4e4hBBZc explains it all]] by stating that [[spoiler:yes, literally everything can be reset]].
* In ''VideoGame/{{Half-Life 2}}'', you follow the refugees' route out of the city. This route is filled with headcrabs, zombies, elaborate physics puzzles, and various and sundry obstacles to overcome. How did anybody not named Gordon Freeman get through there alive? And why weren't the physics problems already solved by the time you got there?

* In ''VideoGame/{{Hexen}} II'', the player comes across many messages left behind by a previous adventurer named Tyranith, who, like the PlayerCharacter, is trying to kill [[BigBad Eidolon]] and [[HorsemenOfTheApocalypse his generals]]. But then, when you start killing those generals yourself, the notes keep coming, implying that Tyranith had already killed them. Turns out, [[BadAss he did indeed kill all four generals singlehandedly]] and was on his way to deal with Eidolon, but then [[spoiler:you find his last note]]. It explains that Eidolon's [[spoiler:power source, the Chaos Sphere,]] has revived the generals (which is why you had to kill them all again), and [[spoiler:that he expects another battle or two will result in his death. A few rooms later, you find his corpse.]]

* In ''VideoGame/{{Warcraft}} 3: The Frozen Throne'', after Illidan proceeds through the Tomb of Sargeras to get the Eye of Sargeras, there are still a lot of monsters left for your pursuing group to fight. Probably justified since he's a half-demon and could hypnotize them or something.

* The ''VideoGame/{{Myst}}'' series of games do a good job of providing a setting in which you are following in the footsteps of people who had been there before you. But most of the levers and buttons have been left in positions that leave the machinery in the least useful configuration. This is justified in ''VideoGame/MystIIIExile'', as the puzzles have been deliberately set up by the BigBad. But in game 1, did Sirrus and Achenar go around resetting everything on the various worlds just for the fun of it before getting trapped in the prison books? In game 2, who left all of the bridges and doors in their locked positions, if some of them could not have possibly been closed from the other side?

** But {{averted|Trope}} in the [[VideoGame/GoldenSunDarkDawn third game]] with the Konpa Ruins. A path is clearly shown for Noelle, a competent water adept, and Kraden to quickly travel to the center of the ruins (much faster than your path, anyway) where you meet with them. [[spoiler: [[PointOfNoReturn You'll never get to use it yourself, though, because you don't have a water adept and you can't go back to that area without the use of a glitch]].]]

* Drinno, the dungeon under the druid school on Gratogel in ''{{Albion}}''. Okay, so it's somehow full of deathtraps from a war between the druids and the Kenget Kamulos (a civil war so internal they fought it within one building, I guess), but how can there be a million puzzles and traps blocking your way when you're looking for someone who went through the whole thing not long ago?

* In ''VideoGame/{{La-Mulana}}'', [[spoiler:Lemeza's father, Shorn,]] is implied to have gone through the ruins first, but there are no traps sprung, items taken or bosses defeated. This was [[LampshadeHanging lampshaded]] on the official blog, then summarily forgotten.

* ''VideoGame/RadiantHistoria'''s dungeon under the Granorg royal palace is the pathway to a ritual chamber all the royals go to once a generation to SaveTheWorld. When you go in there to stop the BigBad from killing the MacGuffinSuperPerson, who both went in there not five minutes before you did, it's filled with block puzzles and PreExistingEncounters. Putting aside [[MalevolentArchitecture why such a vital place of power even has these things]], why are they still active? While the BigBad has an excuse for being able to pass them unmolested -- he's literally superhuman -- the lone MacGuffinGirl has no such excuse.

* ''VideoGame/GodOfWar'' features this in spades. When Kratos traverses the dungeons to get to [[MacGuffin Pandora's Box/The Sisters of Fate]], he finds that hundreds of adventurers have died trying to get the treasure as well. (Their bodies are lying all over the place, and you even fight a few others en route in the second game.) This is all very well and good, except that not only do many of the doors require all manner of oddly shaped keys to open (from a ram's horn to ''specific human skulls'') but also in order to progress it is often necessary for Kratos to smash through walls and on occasion destroy entire buildings. Apparently the temples rebuild themselves every time someone eats it on the way there.

** Sometimes, the puzzles aren't reset to their ''very'' beginning, leaving Kratos to finish a puzzle that a now dead guy started. For instance, in God of War 2, Kratos finds the Hail of Boreas [[spoiler:in the hands of a Spartan who got killed when trying to navigate a spiked floor puzzle. So some Spartan found the Hail of Boreas, possibly killing whatever was likely guarding it, and took it with him all the way down to a lower level of the island.]]

A path is clearly shown for Noelle, a competent water adept, and Kraden to quickly travel to the center of the ruins (much faster than your path, anyway) where you meet with them. [[spoiler: [[PointOfNoReturn You'll never get to use it yourself, though, because you don't have a water adept and you can't go back to that area.]] [[DevelopersForesight Using the glitch near the end of the game that allows you to go anywhere in the map without a cheating device, though, it's revealed that it's not even coded to respond to the appropriate Psyenergy.]]]]

** Averted and played with at Macalrina Temple. Yuna and Seymoer have already gone ahead, and to get to the waiting area outside the chamber of the faith you simply need to walk down an ice filled hallway. Upon the plot-twists and turns therein, on your way out the puzzle's reset (presumably as a trap) and you have to solve them to leave.

* ''{{Uncharted}}: Drake's Fortune'' is also full of this: whenever you open a secret entrance via instructions apparently only found in Francis Drake's journal, many of which require moving heavy objects or activating switches, chances are there are a bunch of heavily armed mercenaries down there waiting for you for no explained reason.
