Probably the best in the series.
Quidditch is pretty fun, though I would of liked a bit more control over flying, sometimes I feel I could just let go of the controller and it would do it all itself! Lol.
Gamespot's review seems to keep comparing it to the book, but from what I can tell, the games are more based off from the movies. And in the movie, there wasn't much of anything else but making potions in Slughorn's class and playing quidditch.
While it's short, it has replayability in my opinion. I'm definitely going to play it all over again. It's a must grab for any HP fan, and at least a rent for anyone else.
