maybe not worth buying. i say its more of a rent game.
then some time later i went and bought it and i wish i didnt.
anyway it is definitely worth playing and also alot better than its predecessor.
you can know master spells and upgrade them, explore the whole of the castle, ride on the broom and play quiditch in a far better way than tps.
most of the game revolves around you sneeking around the castle which i heavily dislike doing because it is depressing when theres prefects around.
the lessons and explorations are the best of the game.
the graphics are good for a 2002 game.
the music is slightly repetitive and annoying but it fits with the locations.
overall just rent it. if your a harry potter fan then buy it but other wise dont do it.
