LEGO Harry Potter: Years 1-4



Lego Harry Potter: Years 1-4 is a video game based on the first four installments of the Harry Potter series in LEGO form. The game was released on June 25, 2010. It was developed by Traveller's Tales, which have also made several other LEGO games, and published by Warner Bros. Interactive Entertainment.

A special Collector's Edition version of the game will be released containing a Behind the scenes look at the game, a free set of avatar clothes, if the game is for Xbox 360, an exclusive set of House crest magnets, and an interview on the making of Deathly Hallows.

Gameplay
The game is based on the first four books and films of the Harry Potter series: Philosopher's Stone, Chamber of Secrets, Prisoner of Azkaban and Goblet of Fire. The main playable characters are Harry, Ron and Hermione. The game features a total of 167 characters who can be unlocked by finding the special tokens hidden around the Hogwarts secret places and level missions, and then buying them at Madam Malkin's. The sub-missions include seeking for Red Bricks, the Golden Bricks, the mentioned Character Tokens, saving Hogwarts students and the True Wizard achievements. Harry and his friends will learn in the Hogwarts castle how to use spells, charms, jinxes, and preparing potions, as well they will visit a lot of familiar places like Hogwarts Castle, Diagon Alley, the Forbidden Forest or Hogsmeade.

Harry Potter and the Philosopher's Stone

 * Albus Dumbledore does not use the Deluminator to put out all the lights out on Privet Drive.
 * The cat at Privet Drive is not the Animagus form of Minerva McGonagall but just a normal black tabby.
 * Vernon Dursley's hair and moustache colour are brown, but in the book he is blond.
 * When Hagrid arrives at Privet Drive he crashes the flying motorcycle into the flower beds.
 * Dudley's birthday is skipped, and Piers Polkiss is absent.
 * The letters from Hogwarts come from more places in the Dursley home, such as the toaster, the washing machine, and in between the windshield-wipers of their car while driving to the Hut-on-the-Rock.
 * In the book and movie Vernon tries to shoot Hagrid with a Double Barrel Shot-gun, but in the game Hagrid simply scares the Dursleys by barging through the back, scaring them and causing them to break. Also, Hagrid does not give Dudley a pigs-tail, or give Harry a birthday cake.
 * The goblin that Hagrid showed Harry's keys to, appeared to have been taking notes. But when the goblin goes to fetch Griphook, Hagrid caught a glimpse of the paper, revealing it to simply have been a child's drawing of a house.
 * At the Leaky Cauldron, the customers aren't in shock when they see Harry.
 * In the game Griphook opens Vault 712 which had goblins discoing to the Harry Potter theme.
 * Hermione doesn't meet Harry and Ron on the Hogwart's Express; they met each other on Platform 9 & 3/4. Also, Ron tries fixing Harry's glasses with reparo, but fails and turns a wizard's hat into a frog.
 * Pansy Parkinson is absent.
 * Lee Jordan does not have dreadlocks.
 * In the book and film, Hermione hides in the bathroom because Ron made fun of her. In the game, she cries because Malfoy threw a brownie at her face before dinner.
 * It takes much longer for Ron and Hermione to catch Snape's clothes on fire. Also, Quirrell is seen jinxing the broom at the same time.
 * In the movie Ron, Harry and Hermione are scared of Fluffy. In the game Ron pulls out a Trumpet and plays "Hedwig's Theme" (albeit very badly).
 * Ron searches with Harry in the Restricted Section.
 * Snape and Quirrell do not have a confrontation during Harry's search in the Restricted Section.
 * Marcus Flint is the Slytherin Quidditch team's seeker.
 * In the book and film, Ron sees himself in the Mirror of Erised as head boy, Quidditch captain, and winner of the Quidditch Cup. In the game, he sees himself in a Quidditch uniform, and Hermione appears to kiss him on the cheek.
 * The Norbert part is only available in a time-turner mission where you have to help Hagrid to heat Norbert's egg.
 * There are some differences in the unicorn part:
 * 1) There's a sick unicorn at Hagrid's Hut. Malfoy unintentionally scares the unicorn, and it runs off into the Forbidden Forest.
 * 2) Hagrid treats his sick unicorn like a child, cradling it in a blanket, taking its temprature, and making it lay in bed.
 * 3) Harry, Ron, Hermione, Hagrid, Fang and Malfoy go into the forbidden forest to find the unicorn.
 * 4) Voldemort simply creeps up on the unicorn, and attempts to eat it, using a fork and knife, but never killed it.
 * 5) Voldemort attempts to kill the unicorn after Firenze scares him.
 * Snape doesn't get bitten by Fluffy.
 * Harry, Ron & Hermione see Quirrell walking up the stairs to the forbidden corridor, and they are seen by Quirrell when they enter Fluffy's room. In the film and book they don't know who wants to steal the Stone until the last room, though they believe it to be Snape.
 * The Trio tricks Fluffy with a rubber duck toy, in order to distract him so that they can fix the broken Harp.
 * Ron doesn't fall unconscious during the chess-game. Instead, he falls over the chess sword while following Harry & Hermione to the last room.
 * Harry and Hermione have to fight Voldemort/Quirrell, instead of just Harry. This was probably changed to make it more co-op friendly. In the movie, Hermione goes and gets Dumbledore.
 * Voldemort spins Quirrell's head to see his face and fight Harry and Hermione.
 * When Harry touches Voldemort in the face, his parents applaud for him in the Mirror of Erised. When Harry is knocked unconscious by Voldemort, Harry's parents laugh at Voldemort.
 * In the book and film, Quirrell dies from touching Harry. In the game, Harry fights Quirrell, he pulls Quirrell's arms off and Quirrell survives, but is seen in the Hospital wing heavily bandaged.

Harry Potter and the Chamber of Secrets

 * The Dursleys have a sign in their room which is supposed to mean: "No wands used in this house!" or "No magic in this house!".
 * The Dursleys are not wearing formal clothing during their meeting with the Masons.
 * When Harry enters his room at Privet Drive, Dobby is throwing his books in the bin because he doesn't want Harry to go back to Hogwarts.
 * When Mrs. Mason is hit by the pudding, Dudley starts to eat the pudding from off her head.
 * The Dursleys install a security fence in their backyard, in addition to the bars on Harry's window.
 * Fred and George do not come to rescue Harry, instead it is just Ron, but in the novel and movie they do.
 * The garden gnomes are featured in the Burrow's garden, unlike the film.
 * Molly Weasley does not send a howler to Ron for stealing the car.
 * Ron's broken wand is only shown to malfunction twice, during an optional scene in Hagrid's garden where Ron spits up slugs, and when Lockhart attempts to use it to erase Harry and Ron's memories.
 * Lavender Brown is absent.
 * Gilderoy Lockhart's wand does not get thrown out the window or taken away during the DADA class that he sets Pixies free. Also, Immobulus first immobilizes the pixies, then a second shot kills them.
 * During the Quidditch match, Hermione notices Dobby cursing the Bludger. In the book and movie, Harry finds out after he is in the Hospital wing.
 * The Polyjuice potion does not take a month to brew, although this is deliberately done to save time.
 * Ron and Harry do not facially transform into Crabbe and Goyle, respectively. They merely wear their robes and hairstyles like a hat.
 * Hermone does not notice that she is turned into Millicent's cat until Harry and Ron point it out.
 * Armando Dippet is absent.
 * In the novel and the film, after the Flying Ford Anglia saved Harry and Ron from Aragog, they have to get in. But in the game, the Flying Ford Anglia includes a light-blue flying scooter that Harry rides to escape from Aragog and get out of the Forbidden Forest with Ron in the car but they did this to make it more co-op friendly.
 * Aragog chases Ron and Harry along with his children, but in the book and the film it is just Aragog's family who chases them.
 * Hermione's note about the Chamber of Secrets is just a picture of a basilisk and a pipe.
 * When Gildery lost his memory, he starts making tea.
 * Harry and Ginny fight Slytherin's basilisk together, because Ginny is awake and playable in the Chamber of Secrets, instead of unconscious and being drained of her life force, as in the movie and the book, Ginny wakes up only after Harry defeats the Basilisk alone. This is done to make it more co-op friendly. When the fight starts the Basilisk goes after Harry not Ginny because Riddle needs to drain her life force to become alive again.
 * Salazar Slytherin's Basilisk has a scarlet plume on his head (meaning it is a male, instead of female as in the novel).
 * The basilisk notices Harry when Ginny screams at one of his disembodied eyes.
 * Harry's arm is not pierced by the basilisk fang, Instead he takes it out of the dead basilisk's mouth.

Harry Potter and the Prisoner of Azkaban

 * Bill Weasley and Charlie Weasley are absent, probably because the Weasley family's trip to Egypt is ommited.
 * Aunt Marge starts to mention Harry's parents after she finds a picture of them.
 * In the book and film the black dog appears in front of Harry out from behind the bushes but in the game he is seen on a playground roundabout.
 * Stan Shunpike does not appear as the Knight Bus conductor, but he is a playable character.
 * When the Knight Bus passes between two London Buses it does not squeeze itself as well as everything in it like in the film. Instead it stretches itself upwards allowing the bus to make itself thinner brick-by-brick.
 * The Knight Bus doesn't stop to let an elder lady cross the street.
 * Cornelius Fudge does not talk to Harry when he arrives at the Leaky Cauldron.
 * Buckbeak does not appear to break Malfoy's arm, since he is able to use it to point at Hagrid without effort.
 * Unlike the film, Harry is seen going through the passage to Honeydukes. Also, Fred and George acompany him through the passage.
 * Kellah and Bem are absent.
 * Harry does not have to wear his Invisibility Cloak unlike in the Book or the Film; Draco does not run to tell on Harry, unlike the events in the Book, because that would cause confusion.
 * In the film, Harry throws snowballs from under the Invisibility Cloak at Draco for calling Hermione a mudblood. In the game Draco makes an igloo and uses it like a tank to shoot snowballs back.
 * When Harry and Hermione are trying to warn Hagrid and the trio that Dumbledore, Fudge, and Macnair are coming, they throw more than just a pebble. They also throw a spoon and many other objects.
 * When Hagrid peaks out of the window, you see Harry dressed as a scarecrow.
 * When Harry and Hermione lure Lupin to them, they play a werewolf howl on record recorder, and Lupin walks over with hearts around his head.
 * When Harry casts Expecto Patronum on dementors, they instantly vanish, instead of being repelled away like in the book and film (although in the cutscenes they are simply repelled).
 * In the film, Harry defeats all of the dementors at one time, but he has to defeat them individually in the game.
 * Harry and Hermione only ride Buckbeak up to a tower near were Sirius was being held, not the full way there.
 * In the final boss battle, you have to battle Dementors. In the film, Harry and Hermione just save Sirius without a battle.
 * Lord Voldemort's boggart isn't his own dead body, but it's Harry alive and well. Plus, Molly Weasley's is Lord Voldemort, not the dead bodies of her family.

Harry Potter and the Goblet of Fire

 * Frank Bryce is absent, and is replaced by a milkman.
 * The Quidditch World Cup match between Ireland and Bulgaria is skipped. Instead it starts out with the Death Eaters' attack on the camp.
 * Barty Crouch Sr and Amos Diggory's hair color is gray, however, in the films they are black.
 * Viktor Krum's hair has a flat top, but in the film his hair is shaved off.
 * Nigel Wespurt is absent.
 * Ludovic Bagman is absent.
 * Igor Karkaroff's aide is absent.
 * Harry's argument with Ron is omitted.
 * Charlie Weasley seems to be omitted but it is possible that the Dragon keeper who appears represents Charlie.
 * Harry does not use his Invisibility Cloak to get a sneak peek at the dragons.
 * In the First Task Harry and Hermione fall into the arena, so they are both running from the dragon. It chases Harry and Hermione inside the Hogwarts Castle as well, but this is only done to make it more co-op friendly.
 * The Golden Egg is floating over fire.
 * The Pensieve scene where Harry finds out about Barty Crouch Jr. is omitted.
 * The death of Barty Crouch, Sr. is omitted.
 * The Yule Ball has been omitted, but you are able to purchase certain characters in their formal wear.
 * The Cho Chang meeting in the Owlery is also absent. Though the Owlery is were you unlock her character.
 * Cedric Diggory teams up with Harry during the second and third tasks, but this is only a feature to make it more co-op friendly.
 * When Harry takes a bath he wears underwear while in the book and movies he is completely naked.
 * In the Third task there is a giant living sphinx statue and the riddle of the acromantula written on a wall of the labyrinth as well as an acromantula itself. The sphinx and the acromantula part is not featured in the film, but they are in the book.
 * Harry and Cedric fight Voldemort together so this is yet another feature to make it more co-op friendly.
 * Cedric Diggory does get killed by Voldemort, while in the graveyard, however Dumbledore shows Amos Diggory instructions on how to re-build his son, so Cedric does not actually die in the game.
 * Peter Pettigrew uses Harry's glasses instead of his blood to revive Voldemort. This is probably to make it more kid friendly. Also when Voldemort comes out he is shown with Harry's glasses, and then tosses them back to Harry.
 * Nott is absent, but Crabbe and Goyle are featured in the portable versions.
 * Lord Voldemort allows his Death Eaters to attack Harry although in the book and film he orders them to stand down because he wanted to be the one to kill Harry.
 * The real Moody wears ordinary clothes instead of a white jumpsuit. He also appears to be happy as he waved happily at Dumbledore and Harry when they opened the trunk.
