I have it on pc and it is hell fun and I want to try it on my wii!
It is the best on wii cause when you duel your remote is your wand, when you play quidditch your remote is the brooourstick and when your making potions it is so messy!
I have completed the whole game about 15 times, found all the hogwarts crests (150/150) I got, done all the potions, quidditch and duelling clubs! I had finished the game in less than a day (I am just a natural with video games)
It is easy for me! (But at the beginning I struggle a bit but got the hang of it)
Good luck to everyone who has enter!
Have fun with the game!
