* LetsPlay/PartyCrashers: In their ''VideoGame/MarioKartDoubleDash'' [[https://www.youtube.com/watch?v=Ia-trYpqY9s video]], [[ButtMonkey Nick]] ends up clipping through the ground on Yoshi Circuit, after which he respawns right in front of the finish line and [[YankTheDogsChain doesn't move on to the next lap after crossing it]].

* At one point in the LetsPlay/PartyCrashers[='=] ''VideoGame/MarioKartDoubleDash'' [[https://www.youtube.com/watch?v=Ia-trYpqY9s video]], [[ButtMonkey Nick]] ends up clipping through the ground on Yoshi Circuit, after which he respawns right in front of the finish line and [[YankTheDogsChain doesn't move on to the next lap after crossing it]].

* LetsPlay/PartyCrashers: At one point during their ''VideoGame/MarioKartDoubleDash'' [[https://www.youtube.com/watch?v=Ia-trYpqY9s video]], [[ButtMonkey Nick]] ends up clipping through the ground on Yoshi Circuit, after which he respawns right in front of the finish line and [[YankTheDogsChain doesn't move on to the next lap after crossing it]].

* The [[UsefulNotes/AdobeFlash Flash]] version of Creator/NinjaKiwi's ''Hungry Sumo!'' has a bug where the game [[UnintentionallyUnwinnable outright crashes]] if your sumo(s) hit an enemy sumo, which explains why the game cannot be played directly on the website. Even worse? The game was discontinued, destroying any chance of having the bug get fixed. But hey, at least the mobile version's fully functional.

** One especially funny (but more misread than actually bugged) example is the warblade power "Iron Heart Surge" that lets you end a negative condition. It specifically says that it ends the effect ''on you'' rather than removing the ''source'' of the effect, but the very vague wording made players think that a warblade who suffers sunstrokecould use this to ''kill the sun''. It's obvious it was meant to act as a HeroicSecondWind, but because of how actions work you can't actually use it while stunned, restrained, unconscious, etc which is the iconic time for it to kick in.

* In ''VideoGame/ClockTowerTheFirstFear'', one possible way to escape from Scissorman among others is to run into the garage and either hide in the car or climb up the ladder and onto the above shelves. The latter, however, is incredibly unpredictable. If it ''does'' work, Scissorman will walk off, and usually when it works, it can be done by simply making Jennifer hug the ladder or stay up on the shelf without doing anything else to the ladder. If it ''doesn't'', Scissorman will climb up the ladder and come after Jennifer, cornering her into a wall to kill her, the solution of which is to kick the ladder down. Unfortunately, since Jennifer has the incredible jumping skills of VideoGame/{{lemmings}} leaping from a pixel-high ledge, she can't leap down and traps herself on the shelves while Scissorman eventually crashes down to her from above and corners her until he kills her. The bug, however, is that, either by him climbing to her or her trapping herself there, a glitch can happen where the game has temporarily forgotten there was a wall at the far left corner of the shelf, so Jennifer will walk all the way to the left backwards until she walks off the screen, and Scissorman will follow her off-screen as well where she won't die but you can't do anything more than reset.

* In the Switch port of ''VideoGame/ResidentEvil0'' (and ''only'' in this port), when Billy and Rebecca split up, if the non-controlled partner dies, the game implodes on itself and just crashes or reset to the prologue cutscene if no save data is detected.

* ''LetsPlay/PartyCrashers'': At one point during their ''VideoGame/MarioKartDoubleDash'' [[https://www.youtube.com/watch?v=Ia-trYpqY9s video]], [[ButtMonkey Nick]] ends up clipping through the ground on Yoshi Circuit, after which he respawns right in front of the finish line and [[YankTheDogsChain doesn't move on to the next lap after crossing it]].

*** Version 2.0.0 gives us another bug, this time even more dangerous. The conditions to activate it are also easier, as all it involves are using the characters Duck Hunt, Mii Swordfighter, or Piranha Plant in [[MultiMookMelee All-Star Smash]]. Once you quit the match, the effects start to occur, ranging from annoyances like [[LoadsAndLoadsOfLoading increased loading times]], to your save data being cleared completely. If you bought Nintendo Switch Online, then you can thankfully use a save data backup, but if you haven't... well, hopefully you have enough time to spare to unlock everything again. This was later fixed.

*** After completing the Thunder Dragon's portion of the song during the Song of the Hero quest, if you go and talk to Golo the Goron and have not started the other two quests yet, the event triggers will not happen and the game could not be completed. In early 2012, Nintendo released a patching program on the Wii that downloads the patch and fixes save files. This glitch was completely fixed in the UpdatedReRelease Switch version.

* [[https://www.youtube.com/watch?v=8Q2P4LjuVA8 "The Glitch"]] by ''WebVideo/CorridorDigital''.

* ''VideoGame/{{Glider}} PRO'': The engine limits the number of dynamic (i.e. moving, collectable or otherwise animated) objects that can be onscreen at once. Usually this is not a problem, since the LevelEditor also limits the number of dynamic objects that can be placed in a single room. However, 9-Room Mode (strongly recommended for many houses) displays as much of the eight adjoining rooms as will fit on the monitor in its current resolution, including some (but not all) types of dynamic objects. The game does ''not'' give objects in the room currently being played priority above all others when deciding which ones to omit, which may potentially result in a vital grease can being despawned because the player's monitor resolution was too high.

** The UsefulNotes/WiiU version of ''VideoGame/BatmanArkhamCity'' has a bug, too. On the second playthrough of ''Harley Quinn's Revenge'', the autosave function will stop working and instead return the player to the menu screen, preventing them from getting past the first room.

* ''VideoGame/BubbleBobble Revolution'' for the UsefulNotes/NintendoDS had to be recalled and replaced because the boss didn't appear on level 30, meaning it was impossible to reach levels 31-100.

** For some copies of the UsefulNotes/PlayStation2 version of ''VideoGame/RatchetAndClankGoingCommando'', you'll end up at a black screen after the opening cutscene. If you get past that, you'll be at the loading screen which loops infinitely.

** The UsefulNotes/PlayStation2 ports of ''VideoGame/RatchetAndClankSizeMatters'' and ''VideoGame/SecretAgentClank'' have an unfortunate tendency to soft-lock while saving when being played on American Slim [=PS2=] models, which not only leads to a corrupted save, but also a giant circular scratch on the disc, leaving the game unplayable.

*** Due to a (highly possible) memory leak issue, playing the game for an extensive amount of time could result in a Vergil player data leaking into all of Dante's save data, corrupting them almost entirely. All of Dante's Devil Arms and Style upgrades are gone (with the game incorrectly giving him Dark Slayer Style, which is exclusive to Vergil), he is stuck T-Posing, and depending on how far you got with him on [[NewGamePlus repeat playthroughs]], then Dante's mission progress will be all messed up. The only way to counter this is to reset the game entirely in between missions if you want to continue or switch characters. Thankfully, this has been fixed for the UsefulNotes/NintendoSwitch version.
*** The UsefulNotes/PlayStation3 release of the game also has, for unknown reasons, Kalina Ann's grapple not working most of the time. The game will also randomly crash on menus and cutscenes, forcing a hard reset of the console itself.

* The UsefulNotes/GameBoyAdvance version of ''VideoGame/TheLordOfTheRingsTheFellowshipOfTheRing'' was plagued with bugs. Most of them were merely agonizing, but there was one place where, in order to progress, you needed to save the game during the FadeOut between scenes. If you time it wrong, you lose the save file.

* The "Over Achiever!" achievement in ''Franchise/{{Cars}} Race-o-Rama'' for the UsefulNotes/Xbox360 won't unlock after meeting the criteria of earning all the other achievements due to a bug.
* Demolition Racer was so notorious for its glitches when it was first released on the UsefulNotes/PlayStation, with certain models having glitchy sound after a few races or sometimes, game crashes under the same reason. The game's camera also causes problems if the player crashes into something. These problems also happen if you were playing the game on the [=PS2=], but fortunately [=PS3=] owners wouldn't have to worry about these bugs. And, given the same engine, this happens on the [=PS1=] versions of the 5th-generation ''VideoGame/TestDrive'' games.

* In ''[[VideoGame/SegaSuperstars Sonic & All-Stars Racing Transformed]]'', the first-day UsefulNotes/WiiU update prevents the Boost Challenges from loading the extra boost pads or any of the checkpoints. As the goal of the Boost Challenges is to pass through a certain number of checkpoints, they become impossible to clear. The first Boost Challenge appears near the beginning of the single-player mode as a mandatory mission, so this glitch effectively stops Wii U players from accessing much of the game. However, it is possible to skip these challenges by [[MercyMode failing three or four times on Easy difficulty.]]

* ''VideoGame/WWFNoMercy'' on the UsefulNotes/Nintendo64 will, without any explanation or warning, delete all saved data on the cartridge. This is more than a faulty battery, it's something in the game's code that causes it. Even players on emulators (where cart batteries aren't even a factor) have experienced this bug. This glitch is present on both American and European versions (with the latter receiving a revised copy).

* ''VideoGame/TheHorde'' for the [[UsefulNotes/ThreeDOInteractiveMultiplayer 3DO]] was infamous at the time for deleting all your save files of other games. A fixed version was released after great outcry. Even worse, [[http://users.polytech.unice.fr/~buffa/videogames/3do_faq2.4.html#section4 according to a 3DO FAQ]] it was originally deleting non-Horde save data ''on purpose''.

** The arcade version of ''beatmania IIDX 9th Style'' was the first to run on Windows XP-based PC hardware rather than their legacy "Twinkle" hardware (derived from the original UsefulNotes/PlayStation, similarly to Konami's ubiquitous "System 573" hardware). It was noticeably buggy: playing "Quasar" will sometimes cause the game to freeze, forcing a reboot. Additionally, "General Relativity" had a glitch causing it to use the timing windows of the last-played song. If it were played as the first song after the machine had booted, it triggers a hilarious bug in which [[https://www.youtube.com/watch?v=xpUX-Dq7K78 you cannot get any note judgments other than POOR]], making the song {{unwinnable}}. Later versions (which also changed the OS from Windows XP Professional to Windows XP Embedded; nowadays the game runs on Windows 7-based hardware) had fewer of these glitches...except for one:

* The UsefulNotes/Commodore64 port of ''VideoGame/RType'' has a bug that makes the first boss [[UnintentionallyUnwinnable unbeatable]].

* The UsefulNotes/NintendoSwitch port of ''VideoGame/TerraFlame'' had a bug where the player's [[AttackDrone Roll Units]] may disappear when losing one point of shielding, even though the player was not killed, which is supposed to be the only way to lose the Roll Units. If this happens, the player's ship becomes severely handicapped. You cannot perform {{Charged Attack}}s and the shots that would come out of the Roll Units are absent; with your DPS shot to hell as a result, good luck trying to beat bosses before their timers run out. Perhaps worst of all, the game does not properly unset the "player has Roll Units" flag: The Charge meter is still presesnt despite your inability to charge up your weapon and the game continues to prevent Roll items from appearing (which is only supposed to happen when you do have Roll Units on your ship). The only way to get out of this state is to die and respawn, assuming you have lives to spare. After this bug was brought to the developer's attention, it was fixed.

* ''Zynaps'' is unfinishable on the UsefulNotes/AmstradCPC because faulty collision detection makes a gap in the last stage too narrow to clear.

** [[PortingDisaster Especially]] on the UsefulNotes/NintendoSwitch version but potentially on any, the Enrichment Ritual -- in which all of your followers donate coins to you, with a higher amount depending on their loyalty level -- will eventually become unusable if you have enough extremely high level followers, because the game generates ''every single coin'' donated as an object in the animation. It may crash the game before the animation can even ''start''.

* In the original ''VideoGame/LifeAndDeath'' (or at least the [[UsefulNotes/AppleII Apple IIGS]] port thereof), if the player drags the drape off of the screen, the game will crash. This can happen within a minute of starting the game.

* ''VideoGame/MicrosoftFlightSimulator X'' will crash to desktop anytime the user right-clicks more than a few times if they are using Windows 7. This is made even worse by the fact that Microsoft markets the game as "Games for Windows"-their line of software explicitly said to be compatible with Windows. The only fix is replacing a hidden file with an older version. This is fixed in the {{UsefulNotes/Steam}} version of the game.

* The UsefulNotes/{{Amiga}} football game ''Kick Off 96'' suffers from an infamous bug whereby first half injury time will continue indefinitely, making each match unfinishable. The game received the lowest mark in ''Magazine/AmigaPower'''s history, with Stuart Campbell awarding it 1% in the [[http://amr.abime.net/review_1774 final issue]].

* The 1990s UsefulNotes/AppleMacintosh skiing game ''VideoGame/MacSki'' went through a spell where it was unplayable on G3 Macs such as the first-generation iMac — the skier wouldn't move an inch. This was due to said computers being so fast at the time that the frame rate algorithm was underflowing to zero.

** ''VideoGame/TonyHawksUnderground'' has a pretty nasty one in the UsefulNotes/NintendoGameCube version. If you're playing on the Sick difficulty, and if you're doing the Bowl Grind mission in the Tampa level, there's a chance that you'll miss EVERY bottle, even if you knocked them over, as it results in a failed mission. The only way to solve this bug is to play on a lower difficulty.

* ''[[http://www.intellivisionlives.com/bluesky/games/credits/intv0.shtml#wc_baseball World Championship Baseball]]'' for the UsefulNotes/{{Intellivision}} was released with a bug that occasionally causes the game to crash and display a debug screen. The original programmer had been working on fixing this bug before Mattel Electronics closed down, but their successor INTV didn't see correcting minor flaws in nearly-finished games before releasing them as worth the expense.

* The UsefulNotes/PlayStation3 remake of ''VideoGame/MetalGearSolid2SonsOfLiberty'', when played at standard definition in the European version, had a glitch which caused a conveyor belt to appear empty when it should be transporting boxes. It wasn't an issue at lower difficulties, but in Hard mode or above the player is required to disarm a bomb attached to one of these boxes, making the game impossible to complete. A patch to fix this issue was released 3 months later.

* The ''UsefulNotes/PlayStation2'' version of ''VideoGame/JustCause1'' has the game crash when loading a game for the second time, which only happens on some models.

* The UsefulNotes/{{N|intendo 64}}64 game ''VideoGame/BattleTanx'' has an infinite health cheat, but the game doesn't always let you turn it off. If you use the cheat during a bonus level, where the objective is to survive for as long as possible, you enter a situation where the bonus level will never end because you can't turn the cheat off.
* In the UsefulNotes/ThreeDOInteractiveMultiplayer port of ''VideoGame/BrainDead13'', when you chose the shave in Vivi's Funeral Salon, just when she's about to [[OffWithHisHead cut off your head]] with her SinisterScythe... all of a sudden the game turns black and you just get sent back to the Main Menu screen for no reason other than a glitch. (Nervous Nick of Website/{{ScrewAttack}} even lampshades this in his [[http://www.gametrailers.com/videos/10mj8f/screwattack-s-video-game-vault-video-game-vault--brain-dead-13 review of the 3DO port]].) Version 1.1 of the port thankfully fixes the glitch.

* In the UsefulNotes/IBMPersonalComputer version of ''VideoGame/PinballConstructionSet'', adding too many parts to the board prevents you from saving the game... or from removing parts so it ''can'' be saved.

* The creators of ''UsefulNotes/RPGMaker FES'' for the UsefulNotes/Nintendo3DS accidentally added a couple of pieces of DownloadableContent called "Dummy", one of which is free, while the others cost money. Downloading one of these will crash the game, and cause the game to crash whenever you try to access the DLC shop subsequently. Deleting all DLC data from your SD card does not fix this, and if you do this, you've just removed all DLC data and can no longer play any user-made games that require these assets.

*** Early in the game's life, many people who played as Peach in "For Glory" mode were horrified to discover being automatically kicked out of the match and banned from online play for [[LongerThanLifeSentence extreme amounts of time]]. This was because Peach's Vegetables are treated by the game as an item, and the game mistakenly detected their use as [[NoFairCheating hacking items into a mode where items are disabled]]. This was thankfully soon fixed, with the bans overturned.

*** Due to the faulty checksum in the game's PasswordSystem, it's a relatively trivial matter to get glitch items that will semi-permanently corrupt a slot in your inventory. While possible to clear up[[note]]On Halloween only, a villager may turn one of the corrupted items into candy[[/note]], it's very difficult to do so.
