FutureGamez: Is it a book? Is it a game? Is it a spell manual? After playing this game for several hours now I'm not really sure I can say which one of those is true - it's a blend of all three really as Wonderbook: Book of Spells is an interactive story book set in the Harry Potter universe - and yes, even J.K. Rowling has had an input into this title. That's certain to gain interest from millions of fans worldwide.
