I have, just this evening, completed Guitar Hero on the expert difficulty. Here, lookit:
Not the best of pictures, but you can definatley make out the important bits. My legendary show will be talked about for years.
So yay - mostly because now I can focus my attention on Kingdom Hearts II which I preordered so I could play it as soon as it came out, and yet for some reason I was completely distracted by the fact that I was yet to master Guitar Hero. Oh well - consider itself mastered.
w00t! I am a GUITAR LEGEND!!!
