Continuity mistake: If you go into the Hyperbolic Time Chamber and Buu comes in count how many people are in there. Three, but in "The Legicay of Goku II" Mr. Pope Says only TWO can go in.
Factual error: During this game, your mech is carried around from world to world by a Titan class DropShip. Titans are strictly aerospace fighter carriers.
Other mistake: The Prince's Sand Power Meter replenishes over time, no matter what the Prince is doing (Unless of course he is using Sand Powers to deplete it). However, after cutscenes, the Prince's Sand Power Meter is always empty.
Factual error: When you hit an enemy plane with your gun, you can sometimes hear the enemy pilot say: "Damn! My plane's been Swiss-cheesed!" In the Strangereal world (the world where the Ace Combat Series takes place) there is no country of Switzerland.
Plot hole: In the level A Show of Force, Bond has to drive the Q-Bike. It seems that this bike came from nowhere, as it wasn't there the first time he went to the safe house, and 003 was already captured. No one could have put it there.
Continuity mistake: After defeating Blane, Bill will appear and ask you to go to the Sevii Islands. Answer no. He'll then go to the Cinnabar's Pokemon Center and will wait for you there. However, if you fly to his house in Route 25, he'll also be there. He's in two places at the same time.
Factual error: When you reach the champion in Pokemon Gold, you have to defeat his Pokemon. His 4th one, Aerodactyl, knows the move Rock Slide. Aerodactyl cannot learn this move, and it does not appear as a TM in this generation.
Bug: There are two ways to perform this glitch. When the glitch is performed, the game can't progress, regardless of the fact all windows on the current floor have been fixed. Ralph will continue to throw bricks and Felix can still be moved, but the game will stay on the current floor. One way of performing this glitch is to 'die' just as the last window on the floor is fixed. The second way to perform the glitch is to press the fix button on a window and have Ralph destroy the window whilst it's being fixed.
Other mistake: When entering Final Fortress as Team Sonic, Sonic will say "This must be Eggman's headquarters!" however the subtitles make a typing error and leave out the 'be,' reading "This must Eggman's headquarters!"
Revealing mistake: When Clayface disguised as Joker is holding Talia hostage in the movie theater, they are both standing on stage in front of the screen with a movie playing. However, they are not casting shadows on the screen. Also, no shadow appears on the screen when Clayface takes on his true form.
Audio problem: In 'Fleeing the Complex', there is an ending called 'Presumed Dead'. Towards the end of this route, Henry is told that he is the first person to have escaped The Wall. As he is told this however, the person speaking is not moving his mouth.
Suggested correction: Dimitri's mouth was deliberately concealed at that shot, due to him being too small on the screen at that time for the animators to consider adding details. Now, it wouldn't have looked as good if it weren't for his beard.
Then that's also a deliberate mistake.
Bug: Bot Boneyard: Pac-Man lands in the pit and he takes a look around. The shot cuts to what Pac-Man can see. As the shot pans around, the black paint on the walls disappears from shot.
Continuity mistake: When going to the Gotham City Bank, the clock tower bell will begin to ring. Alfred then contacts Batman and says that it's now 12:00 AM and wishes him a merry Christmas. If you look at the clock tower, however, the clock says that it's only 9 o'clock.
Other mistake: In the Big section of the Special Book, the first clue to find Big spells "pillar" "pilalr".
Factual error: Poison's "Nothin' but a good time" is labeled "Ain't Nothin but a good time".
Factual error: Whenever you fly a damaged helicopter where the tail is bent, you can fly just fine. This is impossible, in a real helicopter, when this happened the helicopter would spin out of control and eventually crash.
Deliberate mistake: When players die, the screen of the tablet used in emergency meetings is badly cracked for the rest of the game. Messages sent by other players, when shown, appear unaffected over the cracks to make said messages still readable.
Bug: Return Of The King, Level 4: The Battle Of Pelennor Fields - The orc army is approaching Minas Tirith at the start of the level clip. But as the "camera" pans around, half of the orcs literally disappear.
Continuity mistake: Smithers is shown in Bart's Nightmare with green hair, instead of the grey hair he is usually seen with in the show.
Character mistake: During matches involving Triple H, one of the random tidbits Jerry "The King" Lawler can mention is the match Hunter had on Wrestlemania 2000, where he bested in a fatal four-way "Mick Foley, the Rock and Mankind." Mick Foley IS Mankind, the fourth person in the main event was The Big Show.
