Until Hagrid, a giant man from Hogwarts School found him and introduced him to the wizarding world. Harry became a famous student at Hogwarts and got to be the youngest seeker in a century. Harry, Ron and Hermione found out about a three headed dog guarding a trap door on the third floor and began suspecting Professor Snape who had been interrogating their D. A. D. A. teacher Professor Quirell.

The first four versions of the game were released in 2001 by EA for the PC, MAC, Game Boy Colour, Game Boy Advance, and the PlayStation. The PC version was ported to the Mac by Aspyr in 2002. Another version, for GameCube, PlayStation 2, and Xbox, was released in 2003.
Debug mode can be accessed in the PC/MAC version of the game as it is built on the Unreal Engine. It includes things like ghost mode, fly mode, and others.
In the various versions of the game Save Game books appear throughout the game at various places such as the Forbidden Forest, Hogwarts Castle Hagrid's Hut etc. They help the player to save the progress so that the player won't have to restart the game from the beginning.
Controlling of game
In the PS1 version of the game various manuals appear throughout the game on how to control the game, in the shape of blue books.
- Peeves does not appear in the film, but is battled on a regular basis in this game. In the GameCube, Xbox, and PS2 versions he only appears in a cutscene, but is never battled.
- In the PC/MAC version, the Forbidden Forest part is not included.
- In the film and book, Harry's broomstick is jinxed in the first Quidditch match. In the PC/MAC and PS1 version, both Quidditch matches have no Jinxed brooms or accidents. In the PS2/Gamecube/Xbox version, the Slytherin match is played on a jinxed broom.
- In the book, Quirrell summons ropes to tie Harry by snapping his fingers. In the film, Quirrell snaps his fingers to make fire surround the area. In the PC/MAC version, Quirrell moves his hands to conjure fire around the area. But in the PS1 version, Quirrell does not make fire surround the area, but green ropes do tie themselves around Harry at times. And in all the video games, Voldemort is the final boss.
- In the PC and PlayStation versions of the game, Norbert seems to appear early in the game, unlike in the book and movie where he appears nearly at the end of the story.
- Norbert is omitted in the PlayStation 2, Xbox, Nintendo Gamecube and Game Boy Advanced versions of the game.
- Originally Reparo, Verdimillious and an unnamed spell were to appear in the PC/MAC Version of the game. Also Incendio and Wingardium Leviosa were to have more uses.
- The Dursleys were to appear in the PC/MAC Version of the game because they have their model files still in the game.
- Harry constantly fights Draco on a daily basis. Though, in the book and movie, Harry doesn't fight Draco at all until Year 2.
- In the GBA version of the game, Harry gets caught by Professor Snape instead of Filch, and Harry's detention in the forest isn't the same as the book or movie.
- In the GBA version of the game, Harry uses Flipendo on the Troll and it falls in a hole in the girls bathroom. In the book and Movie, Ron used the Levitation Charm on the troll's club to bash the troll's head with it.
- However, in later parts of the game during the detention in the forest, it's possible to use the said charm on the trolls despite there being no gaps to push them in (using it on them causes them to smack their own heads and if cast on them five times they will fall over and remain out cold).
- In the PlayStation 2 and Xbox versions of the game the Quidditch Match against Slytherin is at the last match of the year rather than the first.
- In the PC, PS1 and PlayStation version of the game, Harry gets trapped in the dungeons during Potions class.
- In the PlayStation 2, Xbox, Gamecube versions of the game, Harry goes alone in the Forbidden Forest.
- The GBC Version of the game has a glitch during the part where you need to find ingredients for Snape. One of them is supposed to be found by examining a tapestry in Snape's office. However, if you get the other ingredient first, the one in Snape's office will never appear and you will be forced to restart the game.
- In the beginning of the PC/MAC Version of the game, Dumbledore, when greeting Harry Potter in the beginning of the game, tells him about a story about finding a room with a lot of toilet pots, and the next time he found lots of fire tortoises. This was actually taken from a brief conversation Dumbledore had with one of the ministry officials during the Yule Ball in Harry Potter and the Goblet of Fire.
- The GBA version of the game is one of the few sprite-based games to have non-ambidextrous sprites for one of its characters; Harry himself has a separate set of left and right sprites to show that he always holds his wand in his right hand.
