The Sorcerer's Stone follows the prodigious wizard through his first year at Hogwarts, where he is joined by characters such as Ron Weasley, Hermione Granger, and even Draco Malfoy. He can explore the grounds at Hogwarts, spend time with Hagrid, or even hop on a broomstick for a quick game of quidditch. However, Harry's special gifts are noticed not only by his friends and instructors, but by darker forces as well, and players may even come facetoface with "YouKnowWho" himself before this adventure is over.

Assuming the title role in Harry Potter and the Chamber of Secrets, players explore a 3D Hogwarts, Diagon Alley, and Forbidden Forest from a thirdperson perspective. They must attend classes so they can learn a variety of spells. Some spells may used on enemies, but if they are not cast correctly, a comical or hazardous misfire can result. In addition to the main adventure, players can participate in a number of minigames.

Inspired by the Quidditch segment in Harry Potter and the Chamber of Secrets, Quidditch World Cup features a choice of four Hogwarts Houses (Gryffindor, Slytherin, Ravenclaw, and Hufflepuff), each fielding a team of seven players. Rules follow those outlined in J.K. Rowling's books, with players flying on brooms and representing four positions: the Keeper (goalie), Beaters (defensemen), Chasers (offense), and the Seeker.
