The game is Ambitious yet unfinished. It could have made a great game with a big more difficulty.
The way you play makes it fun to impovise but there is no real difficulty, Its just a large sandbox. Chosing to play with freinds makes it so much more fun though. The abbility to save and send video's is a nice touch.
The Graphics are the normal Nintendo, Clean and Colourfull. You miss out on the Drums if you don't have a Wii Ballance board, If you do have a Ballance board you get to have a very nice complete tutorial on how to play.
All this game needs is a bigger range of game modes and the abillity to download more songs, There should also be more too unlock too, and if there is more to unlock it shouldn't be unlocked so easily by completing tutorials but instead for game accuracy.
