I had someone say I was the "best guitarist" they'd seen on rock band for awhile, after on band quickplay I got something like 90% on one of the Green Grass & High Tides guitar solos on expert. That was pretty sweet. I play against this mate of mine who is amazing on rock band and completed Guitar hero 3 on expert (even I can't do that) and when I beat him, oh man it's so great. I was also majorly complimented when he said that, out of all the people he plays against, I'm the only one he has to try to beat. I was like !
