Controller malfunctioning

A controller being malfunctioning is a symptom that it causes the controller's buttons to respond itself without pressing or worse, not work propely which makes the game even more harder much to frustrate players to the point it makes the game unbeatable until the player buys a new brand controller.

Causes

 * 1) It turns to a game that as smooth and responsible controls to very clunky and unresponsive controls whenever the buttons respond itself which causes the player to suffer from cheap deaths, car crashes (even worse in games that uses crash cams like the Burnout series), etc: making the games severely harder even in games that are not hard enough to the point it makes the game unbeatable until the player buys a new brand controller.
 * 2) *Additionaly if a game has clunky controls like Bubsy 3D, Superman 64 or Dick Tracy it makes it even more clunkier and unresponsive than usual and gets far more worse in games that are hard enough to frustrate the player such as mh:awesomegames:Dark Souls, mh:awesomegames:Cuphead, mh:awesomegames:Super Meat Boy, etc:
 * 3) *It also makes the annoying and difficult missions/sidequests unbeatable due to it's clunky controls such as the Demolition Man from mh:awesomegames:Grand Theft Auto: Vice City, Supply Lines... from mh:awesomegames:Grand Theft Auto: San Andreas, the Guido Kart Races from mh:awesomegames:Cars: Race-O-Rama or the Driving Mission No.34 from mh:awesomegames:Gran Turismo 4 and the Plant a Bug from mh:awesomegames:Sleeping Dogs to name a few.
 * 4) If the main button for jumping/choosing a menu/accelerating a car (only in games from early consoles like the PlayStation 1 or the original Xbox with some exceptions like recent Gran Turismo games) presses itself, this produces cheap deaths, car crashes as well as accidentally pressing unnecesary menus or spending money in useless things. if this button doesn't work, the controller will be unusable after that.
 * 5) If the main button of canceling the menu presses itself (Triangle/Y in the earlier consoles and Circle/B in the later consoles), the menus will close without any warning. If those buttons won't work, the player can't exit those menus as well make the controller unusable.
 * 6) The Triangle/Y button is mainly used to enter/exit vehicles in the Grand Theft Auto games as well as the clones such as Saints Row or Mafia. The player unaware of this, enter or exit the vehicle itself which sometimes it causes to cheap mission fails. If the button won't work propely, the player can't enter or exit vehicles which can be problematic whenever the player's vehicle catches fire to the point it explodes causing the player to get killed.
 * 7) Some games whenever the player must do actions in order to progress the mission has different buttons. for example in Saints Row: The Third and Saints Row IV, requires the use of the Triangle/Y button while in Watch Dogs requires the Square/X button to hack stuff. If those buttons won't work, basically it makes the game unbeatable.
 * 8) If the analog stick buttons works itself, it makes moving the character, sterring a vehicle, or aiming really tedious to the point it makes the game even more hard enough to frustrate so much especially in games that are really hard enough like the aforementioned Dark Souls, Cuphead or Bloodborne to name a few. Also if the analog sticks are stuck to the point that never stand still, it makes it even more difficult to do the aforementioned things. Same applies whenever the D-Pad buttons work itself. Also this can be a very problematic if a game the player can't use the D-pad buttons at all like Grand Theft Auto: San Andreas or mh:awesomegames:True Crime: Streets of LA as well the majority of games released in PlayStation 3 and onwards, forcing the player to either play the game with the badly damaged analog stick or buy a new brand controller. If those buttons won't work, the controller will be unusable after that.
 * 9) If during playing any Mortal Kombat game, if the buttons presses itself during the fatality segment, it makes doing the sequence to perform a fatality very difficult.
 * 10) If a button that requires to press during QTE segments won't work propely, it makes this segment unbeatable.
 * 11) In driving/racing games if the button used to look back presses itself, the player can crash into obstacles without aware of it and makes the game unplayable because the player requires to look whenever the player drives.
 * 12) In games in where the player can't configure the controller scheme at all, if any important button won't work or responds itself, the game became unplayable after that.

Reasons

 * 1) There are games that where the player must mash consistently the buttons especially in fighting games such as Mortal Kombat or Street Fighter which sometimes doing so it damages the buttons and even the analog sticks.
 * 2) Some games like Bigfoot (NES) and My Name is Mayo requires to smash the same button all over again much to damage the buttons especially the mashed button.
 * 3) Ragequitting is common. Whenever the player loses in harder games like Dark Souls, Cuphead. Super Meat Boy, Bloodborne or Battletoads (especially the third level Turbo Tunnel) or also get plagued by trolls/tryhards/griefers (especially in Grand Theft Auto Online in where introduced the infamous hoverbike named the Oppressor MKII which is the main vehicle used by a lot of griefers to kill players) he/she fits into a rage to the point it causes their controllers to break as seen in most of ragequit videos.
 * 4) Also in some games forces the player to rotate the analog sticks constantly to beat the mission/sidequest which sometimes it damages the analog sticks. Examples are the pit-stop minigame in mh:awesomegames:Cars: The Video Game and the infamous and controversial mission "By The Book" from mh:awesomegames:Grand Theft Auto V in where the player during in the torture section with Trevor and Mr. K, the player must rotate the analog stick to pull one of Mr. K's teeths which is required for the gold medal.

How to prevent this

 * Its VERY IMPORTANT to not mash the controller buttons too much especially whenever you play fighting games. In fact if you have a controller with turbo function you can hold pressed which simulates mashing.
 * Also if you're playing My Name is Mayo let the controller take a break or else you severely damage the X button unless if you hold the button if you're using a controller with turbo function.
 * NEVER bite the analog sticks.
 * If you lose in any game, do not ragequit too much. However if you're playing harder games like Dark Souls, Cuphead, Bloodborne etc; simply do not play those games and play games that are not too hard enough.
 * Same applies with the missions/sidequests that are harder like Supply Lines... from Grand Theft Auto: San Andreas or Five Finger Fillet from Red Dead Redemption and 2.
 * In addition of difficulty you can check the difficulty rating in a game in the GameFAQs website. Games with "Just-Right" rating are games that are not too easy and not too hard while in games with "Tough-Unforgiving" or "Unforgiving" those games are not for you if you're unskilled enough. Unfortunately there are games that has "Just-Right" rating but the games are incredibly difficult much to ragequit such as Test Drive Unlimited 2 especially in A5-A4, A3-A2 and A1 licenses from Asphalt license and Sleeping Dogs especially the story missions in where you must plant a bug. However games that are incredibly easy such as Ninjabread Man, SpongeBob HeroPants or Little Britain: The Video Game can make you feel very boring after beating the storyline.
 * Additionally if a game has a difficulty section, you can set the difficulty to "Easy". However this is not always the case because some segments of the game are harder even in the easy difficulty like Shao Khan and Goro in the Mortal Kombat series or the mh:atrociousgameplay:RubberBand A.I. during racing games. Also some games has a achievement/trophy that requires to beat the game in the hardest difficulty.
 * Make sure that you have a backup of a controller in case said controller is broken.
