Well, I've played a lot of World Tour and Rock Band lately, so I'll run down what I've done.

I beat theGH:WT guitarcareer on expert(yes, even Satch Boogie)
I FC'ed(and Re-FC'ed with a better path) Everlong on expert guitar in World Tour
I GS'ed Welcome Home on Voxtar in Rock Band 1
I GS'ed GGAHT on guitar in Rock Band 1(took me long enough)
I FC'ed Living on a Prayer in World Tour(good song, but I HATE the solo in the World Tour version)
I thrashed Scream Aim Fire on expert drums in World Tour(for Wii with the World Tour drumset. I was at a friends house when this happened)
I GS'ed Highway Star on guitar in Rock Band 1
I 5 starred RttH on guitar in Rock Band 1

I've done more, but that's all I wanna list. Peace.
