I decided to play a few songs in Guitar Hero II today to increase my sanity. I haven't played since around Christmas, and I haven't played seriously for longer than that. To warm up, I tried to five star "Crazy on You" on hard. It starts with a complicated into... which I played almost flawlessly... while not concentrating on the screen...
So for a couple of months, I have had the instructions for how to play the intro to "Crazy on You" in Guitar Hero stored perfectly in my long term memory. I hope I'm not forgetting anything useful by using so much brain storage for rhythm games :P
