A magical game to start off with, then you soon see that they don't make the game like the movies and books...
Duelling is OK, the controls for it are fairly simple but you may have a bit more fun fighting friends rather than the computer, because all you have to do is run, spell, run, spell... No skill.
Overall, it is disappointing, I bought this game with the release of the film because I just wanted as much HP as possible, I wanted to feel like I was actually there too. Then this game hits you and reminds you that there is no wizarding world (Unless J.K Rowling is a witch and wanted to give us a clue :P) and that this is the closest you will ever have to an experience in the magical world. Lets hope the new games are better.
