I had my friends over on Sunday for our usual RB get together (every Sunday we play since RB was originally released). My main instrument is drums (since I play them in real life), but we usually alternate at some point since drumming for too long can be exhausting and hard on my back.
So...my victory for the week was playing our entire gaming session on drums, which turned out to be about 5 hours of almost non-stop drumming. I was having a ton of fun...though my back thanked me for it later! :)
