Well for Christmas, along with the Wii, I got Pokemon Battle Revolution and Super Mario Galaxy. Yesterday I bought Metroid Prime 3 and Excite Truck. I might get Twilight Princess, I have been thinking about it.
Yeah it's too difficult. Daniel has the guitar flat on his knees and plays it like a keyboard (style probably has a name that I don't know). He's been playing the piano/keyboard since before I met him when I was 11, so it's naturally easy for him.
