Harry Potter 6 follows the story of JK. Rowling's sixth book, and also adds some good elements to the story.
This game is GREAT for Harry Potter fans because you can walk all over the school and it's fantastic.
The quidditch flying is good, a new addition to the game, also.
The poition-making is fun,but it is boring after a while.
Some "missions" on the story are difficult and tricky to do. You have to read and hear very good in order to get what you have to do.
The graphics could be better. I know that the Wii is not a high-definition gaming system, but the graphics are a little tacky.
Try it, maybe it won't dissappoint you.
