Harry Potter and the Philosopher's Stone is an action-adventure video game based on the 2001 film of the same name. Philosopher's Stone was initially released for Microsoft Windows and the PlayStation in November 2001. A different game bearing the same name was made two years later for the GameCube, PlayStation 2, and Xbox in December 2003. The versions on different platforms differ greatly from each other and do not follow the same level structures or gameplay, with somewhat varying stories as well.
