"Lego Creator" was first introduced in 1998, then came "Lego Creator: Knights Kingdom" in 2000, and then "LEGO Creator: Harry Potter" in 2001. This game was considered to be related to the film version of "Harry Potter and the Philosopher's Stone" and allowed you to play as the different characters and go into four general areas, plus 5 extra areas. The area of Inside Hogwarts school has four place-able extra rooms to reach other areas including the Potions Class and the Forbidden Corridor. You can place minifigures on broomsticks and then fly them around. You can also drive the Hogwarts Express. You can change the weather from rain to snow to night to day and also make it foggy. You can cast a few spells like ones that make fireworks. Also you can make your own minifigures and models with classical and Harry Potter style Lego faces, bodies, cloaks and even wands, while the workshop contains castle pieces, to extras, to standard pieces.
LEGO Creator: Harry Potter and the Chamber of Secrets is a game in the Harry Potter Lego Creator series specifically focusing on the second book and movie.
The world is customisable to an extent. For example, the player can only have a certain number of characters. In addition, the player can only have a few minifigures or animals walking around. However, by clicking on such objects, the player assumes control of them. Certain people or animals can reach certain areas. The player must also complete simple tasks to unlock new areas. These tasks are tutorials, which show the user all the features of the program.
