So far I have all of them except the fifth one.

It took me three months to find the Sorceror's Stone for Playstation. It was like it didn't exist. I also have the Quidditch game (*grumbles* but a friend is borrowing it at the moment - I made him swear on his life that he wouldn't let anything happen to it)

I absolutely love the Quidditch game. I can actually play Quidditch on it, rather than on the normal games.
