Harry Potter seemed to be the perfect game for the Wii remotes abilities, sadly it just doesn't live up to expectations.
The gameplay in this game is very much the same that it has been in previous Harry Potter games. The basis is basically run around doing almost dumb tasks for extras, and gradually getting an extremely bad interpretation of the movies/books (books especially) through cut scenes and lame tasks. The fights in the game are hard, and yet easy to get through. This is based solely on the fact that the Wii remote controllers are quite useless. The controls are mainly tilt the controllers up, or revolve them, or even tilt them down. It feels nothing like a wand would actually feel, which defeats the entire purpose of having the task of waving your arms around while playing the game. You, of course, use the nunchuck attachment to control Harry, and moving in this game is something you really would like to avoid. I'm assuming they wanted movements to be "realistic" maybe, but it didn't work out, it's so hard to control Harry and get around, and to move at any reasonable speed you must press and hold a button which sometimes likes to not work. When that happens your forced to walk at speeds that will force you to pull the hair from your head. The game in the very beginning gives you a room for all of your extras, which include videos of producers and cast, and other small things. You unlock these by gaining points, these are gained by doing various chores around the castle, everything from repairing a statue to putting paintings on a wall that had fallen to the floor. You gain them, and earn levels as you progress. You will end up dreading gaining these levels because an annoying and very slow moving moaning myrtle will come down to let you know there are new extras to enjoy in the secret room! Oh joy, now let me continue with the game, and at least give the option to skip the scene. The puzzles are very easy to get through, and really offer nothing entertaining. The duels you find around the castle are of course made extremely easy by the creators due to the annoying controls which present a challenge to use.
Graphics:
The graphics are, well, really bad. The Wii of course doesn't really exist to give a great visual experience, but you have to expect more then this from next generation games. Harry's character model, from a distance, looks pretty good, but in cut scenes the characters really do hurt to look at. The castle is definitely beautiful though, absolutely gorgeous. It's very big with somewhere to always go. Overall it's not great, but not horrible.
Sound:
The game uses the soundtrack from the movies, which is stellar to say the least. There really isn't much more to say on the music, it's not that bad on the ears. It can get repetitive I suppose, but all adventure games just loop the same song over and over again, so it truly isn't anything new to have a problem with.
Value:
The game offers little to no value for most people. The reward room really isn't worth getting everything for, mainly because the rewards are pretty much a waste of time. The story of the game is not very long lived and extremely boring for most. Die hard Harry Potter fans will probably get a few good hours out of this game, but most probably will end up bored extremely fast. So I'd say it's a rental possibly if you're into Harry Potter outside of the games, but if you don't read the books or movies then you will be bored extremely quickly.
