Big game for the wrong reasons. It's a good RPG, not a good HP game, and it being connected to Harry Potter may as well be coincidental. It really has nothing of the magic of the series, and all Hogwarts is is unfortunately just a nice tour.
They spent so much on details in Hogwarts, which is cool, but they kinda forgot all the activities you're supposed to do there. Like not even a game of wizard chess, like the 5th game.
