Believe me, I've had my fair share of frustrating experiences!

One of those was that time when I was playing Section Z. I was determined to beat it, and I was very far as well. I was on the second last boss, when I got a Game Over again. This isn't so frustrating on its own, but you know, you get a countdown of 10 seconds every time you get a Game Over. I was a little distracted by a friend of mine, and I forgot to press 'start'... So I lost all my progress. I was more than a little upset after that. I spent a whole evening getting so far on Section Z, you know... :'(

In Pokémon fire red when the last Pokémon of the champion had the life bar in red, he use and attack, is super effective and critical, so I lost

My worst moment was during the classic game of bubble bobble. For a year I have tried to get to the final stage and I made it. That last boss was terrible, I have tried to beat him 1,036 times in a single day but still no dice.

 worst moment in pokemon ruby on the last gym could not solve the last puzzle

My most frustrating video game moments is when I was playing Pokémon Silver and I spend 2 hours hunting down Entei (one of the 3 legendary dogs) and when I finally got him to appear I killed it, so I had to turn off the game and restart looking for him all over again. 

Every part of Dragon ball Z:Legend of the super saiyan,just...every bit...especially the saiyan saga.

One of the most frustrating moments are in Capcom Vs Snk 2. The frustrating part of it are the 2 final bosses God rugal and Shin Akuma. I have never had to see the Game Over screen so many times

IN a level is super Mario world where you have to fly it was hard to beat but I finally made it to the flag poll and right before I touched it like 1 frame away from winning I died oh yeah and on star fox 64 I could never beat star wolf to go to the other world oh yeah and at the water temple I died at the boss I was playing the 5 days straight master quest (what was I thinking) and he had one hit left and he grabbed me and I died I then realized I never saved! Also in paper Mario and the thousand year door ugh I cant beat grodus but more specifically that one time he had 1 health point and I die from poison! And my life mushrooms were gone ugh and on the shadow queen sae thing happened except I was on full health points and then bam! My game cube over heats and turns on fire! Ugh and every moment of sonic 1 also on sonic 2 I had no Idea how to kill the boss I died so much and Having to redo those platforms ugh It was so annoying and I would go on but I would rather put it on another post tomorrow my life sucks. This has been a Message from Paper Luigi.

itsme9988 : I don't know why you posted all that scripture before your actual response to the thread .. 

Anyways, HELLO! & How are you? .. I'm great.

Ugh. The most frustrating moment in gaming history for me was Pokémon Fire Red. I was challenging the Elite Four with my team, as you do. The final guy, the champion's Pokémon were so difficult! I couldn't win .. He kept using the same constant move which was super effective towards my last two Pokémon. I was sitting there, I took his health down to 2 HP and he uses Full Restore... I had no PP left on either of my Pokémon... except quick attack, and that done no damage what so ever.

As you can tell, I lost. 

When I fail at fatalities on mortal kombat...

on legend of the dragoon on playstation. when u couldnt hit x fast enough on the combos and the other guy counters.......

My most frustrating video game moment is when I was battling one of the bosses (I forget which one it was) in Mario and Luigi: Superstar Saga and I was trying for at least 5 minutes and right before I was almost done beating him both Mario & Luigi got K.O.'d by the boss and it was a game over.

Falling off a cliff for the thousandth time in Darksiders. I swear for one of the Four Horsemen War sure has a tendency to fall off of stuff.

Of course having the floor go out from under you in the second one because you can't see it due to the camera angle, and therefore didn't see the giant pit before you, isn't much better.

Sorry Death, I guess it doesn't take that much to kill one of the Horsemen after all. Oops.

(Same goes for almost beating one of your opponents only to have them wipe you out. Ha. Oops again.)

The most frustrating game moment ever was in pokemon. I had been playing for hours and had got an awesome team and I had just started a new game. I finally beat the 3rd gym feeling like im forgetting something and I turned off the game shrugging that feeling.
I forgot to save and I remembered to then Cry !

Sonic Generations was a very enjoyable and slightly underrated game, but it had this ONE UNBELIEVABLY F****** OBNOXIOUS SIDE MISSION where you have to play TENNIS with Vector using Modern Sonic's Homing Attack. The camera angles are ungodly terrible, trying to get the Homing Attack to work properly can be frustrating as all hell, and, sometimes, trying to memorize his pattern just feels like trial-and-error, especially when his shots start to fly really fast. You HAVE to hit the musical note that he sends flying at you using your Homing Attack, and if it touches the ground, YOU LOSE; which means that you basically have to start the whole mission all over agaain from the beginning. When I finally completed that f****** mission, I got a D rank, and I currently am not sure how to boost my rank on that stupid mission.
