dont get too excited folks. yes it LOOKS amaizing, and even i spazed out when i first saw it. but i did some research and all you do is shake the remote to the music you 'read'.
if it was more challanging and you pushed the buttons on the remote like you do a real instrument, then i might be interested.
i suggest you rent it forst if you have a Wii, then get it if you really like it. just dont go out and waist your money because it 'looks so awsome zomg!!1!'
Okay, let me clear up a few things for all of you, having owned the game myself.
1) It = Epicness.
2) Yes, you do press the buttons, move the remotes in fashion and play along in time to the music, plus it also allows you amazing freedom to do whatever you like.
3) There are several "styles" of playing, that is, Piano, Guitar, Trumpet, Violin and Percussion. Each of these have several different instruments within it (except violin... it only has violin so far for me. -_-" Double Bass falls under guitar controls.)
4) The game progresses, you unlock different styles and the like, and many other things.
5) It has minigames you can play with your friends.
It is a really well done game, though sometimes the timing of it is annoying in Lessons, but still, fun indeed. I seriously recommend it.
